Replacing the brake fluid Chevrolet Lacetti. Replacing brake fluid Chevrolet Lacetti What brake fluid to choose for Chevrolet Lacetti
Hydraulic driving brake system Chevrolet Lacetti. It has two contours, including with the ABS system. Each of these contours of the car provides the operation of braking wheels of two mechanisms located on the machine in diagonally.
The car also has one tank that is responsible for the supply of the working fluid, both for the clutch system and for the vehicle. The correct performance of the brakes is maintained not only to changing the pads, but also to replace brake fluid (TZh), according to Lacetti Regulations. How to do it - see pictures.
According to the application for use operational liquids For Chevrolet Lacetti into the brake hydraulic system and clutch system should be poured 0.5 liters Brake fluid.
The manufacturer allows brake fluid that meets the requirements of the specification FMVSS116 and DOT4 Standard.
In some manuals, the use of Dot5 on the Chevrolet Lacetti car. It should be mentioned that in the same instructions it is indicated which the TJ should be used, the name of which is indicated on the tank of the main brake cylinder (GTC). Secondly, the DOT5 brake fluid is not compatible with the DOT3, nor from Dot4 +, nor from Dot4 and besides in cars having aBS system not used.
The original GENERAL MOTORS brake fluid has an article 93160363. A similar replacement will be brake fluid "Brake Fluid" from Opel, catalogue number - 1942421, manufactured by Gmotors for Opel cars. Price of this working fluid 450 rubles.
Also available is a wide range of TJ from other manufacturers of Fenox "Sbrake" SBF4005, Miles "Brake Fluid" EBF455, Hella-Pagid "Brake Fluid" 8DF355360011, Miles "Brake Fluid" EBF910. The price of liquid data varies from 100 to 200 rubles.
Prices are relevant for the fall of 2017 for Moscow and the region.
How to change the brake fluid on Chevrolet Lacetti
For this you have to pump out old liquid From the tank, pour fresh, create pressure in the system (shocked a pedal or special device), put on a hose on the fitting (one end of which will be in a transparent bottle with liquid), unscrew the bleeding fitting on the wheel caliper, wait until the fresh brake fluid is without air. It is very important to observe the pumping scheme.
The air from the system is removed with a muffled motor, from the beginning from one contour, and then from the other to which the sequence of pumping of the brakes: the right rear wheel; left front wheel; left rear wheel; right front wheel.
Instructions for replacement DIY DIY:
- We unscrew the cover of the GTC reservoir.
- With the help of a syringe, pump the working fluid from the tank.
- We lay a new TJ to the bottom crown in the tank neck.
It is important to prevent the penetration of air into the hydraulic system of the car. To do this, it is necessary to ensure that its level in the tank fell below the MIN mark.
- Pumping the brakes must be carried out with the subband. Sulling out of the pollution of the brake cylinder of the wheel and remove the protective cap.
- Using the key "On 10" weakening the tightening of the pumping fitting.
- We put on the vinyl hose for one end, and the other omit in the bottle, half filled with brake fluid.
- The subband must squeeze the pedal 4-5 times, having rolling the TJ and keep it in the lower position.
- We continue to unscrew the socket on the ½-¾ turnover. At the same time, old TJ and bubbles of air should go out of the end of the tube, and in the meantime the pedal lives until it stops.
- As soon as the TJ stops flowing, wrapping the fitting and let go of the pedal.
- We carry out the above actions as long as the hose does not fly a new brazersushka. At the same time, the pedal move should not exceed half the distance to the floor.
- We carry out similar actions on another wheel of the same contour (according to the scheme).
- In the same way, we pump the brake mechanisms of wheels of another contour (according to the scheme).
The following is necessary for work:
- assistant;
- transparent tube with a diameter of 4-5 mm;
- transparent bottle;
- special sleep "10 mm";
- tara for draining DH;
- syringe;
- new brake fluid class Dot4.
We produce the brake fluid replacement in the Chevrolet Lacetti car.
We unscrew the brake fluid tank cover.
Pump the syringe brake fluid, but not all, it is desirable to leave a little on the bottom so as not to bring the system.
Take new liquid And fill up to the MAX mark.
Go down and remove the wheel.
We remove the rubber protective case. We dress up a hose for the brake fluid plum fitting.
What are Lycetti liquids apply? Quite often you have to answer questions about liquids and lubricants used in Lacetti. What braking fluid is applied and how much it is necessary, what a coolant and which is its compound volume and the like.

Chevrolet Lacetti. Diagnostics of malfunctions of the crank-connecting rod mechanism
The working qualities of the crank-connecting mechanism can be estimated by measuring oil pressure, determining the characteristics of the dishes and measure the gaps in certain pairing of the crankshaft.
Measuring oil pressure
Oil pressure is checked using a device consisting of a pressure gauge, a junction sleeve with a cape nut and a nipple and a damper that smoothes the oil ripple during pressure measurement. To remove pressure tests in the main line, the device is connected to the housing oil filterBy disconnecting it, pre-with a tube of a regular pressure gauge. To test the pressure, the following operations follows:
Connect the measuring device to the oil filter housing;
run and warm the engine to a standard thermal state;
fix the pressure of the oil in the main highway with idling, at the time of the steady and nominally frequency rotation of the crankshaft.
Listening to the knocks in the pair of crankshaft
The knocks in KSM are listened to certain pairing using an electronic motorcycle. This method of diagnosis of KSM requires a discharge into an overportable space of sparse pressure by means of a special compressive vacuum installation. It is required to listen to the pairing between the piston finger and the piston body, also between the connecting rod mechanism and the neck of the crankshaft, and then between the sleeve sleeve of the rod and piston finger.
In the case when the reduced oil pressure and the knocks in the crankshaft were recorded, the gaps in the above pairing and replacing the oil pressure sensor will be required. If the oil pressure is lowered, but there are no knocks, then the drain valve of the lubricant system should be adjusted. In the event that the actions made will not lead to normalization of pressure, then the diagnostics of the lubricant system will be checked.
Diagnosis of CSM in the width of the gaps in its pairs
The condition of the crank-connecting mechanism is also determined by the magnitude of the gaps in its conjugates. They are measured using a special device and following the following scheme:
Install the cylinder piston in the compressed state;
stupid crankshaft;
Instead of a nozzle, fasten the device in the cylinder head, weaken the locking screw, and then lift the guide up;
turn on the device and bring the pressure to the discharged state;
achieve stable indicators of the indicator by the method of two- or three-time feed cycle;
Fix the gap in the connection between the top head of the connecting rod and the piston finger, and then the total gap between the connecting rod bearing and the top head of the connecting rod.
All gaps in KSM are measured three times and take the average arithmetic value. In the case when the gaps of one of any connecting rod are more permissible values, the engine repair is required.
The malfunction of the crank-connecting mechanism includes a decrease in compression in the cylinders and engine power, an increase in fuel consumption and oil, smoking, uncharacteristic to operate the engine and noise, oils and coolant.
Compression in the cylinder is measured on a heated engine with a compressometer
Before measuring compression, spark plugs are twisted, the rubber tip of the instrument is inserted into the candle hole and turn the crankshaft with a starter at fully open throttle and air dampers for 5-6 s. At the compressometer, the maximum pressure of the end of the compression tact in the cylinder is removed on the pressure gauge scale, and the compressorrograph has a pressure value on a paper form. Measures repeat 2-3 times in each cylinder and determine the average value. The pressure difference in the cylinders should not exceed 0.1 MPa.
Reducing compression in individual cylinders can occur due to the cause or breakage of the piston rings, damage to the cylinder head laying, disorders of adjustment of gaps in the valve mechanism or valve extensions. Cocking the piston rings in the grooves of the piston contributes to the intensive breakthrough of gases in the Carter, which can lead to an increase in the pressure of crankcase gases and computing the oil through the hole for the oil. In this case, each cylinder is poured by 20-25 cm3 motor oil and repeat compression measurements. The increase in pressure indicates a looseness in the cylindrophone group.
Malfunction of block head gasket and tightness disruption in the valve mechanism can be detected using a pneumatic air, passing compressed air through the cylinder hole. Air leakage into the adjacent cylinder indicates damage to the laying of the head of the block or the attenuation of nuts or the cylinder head fastening bolts. The cylinder head laying fault can also be detected by the coolant in the pallet. This will be observed a constant decrease in the level of coolant in expansion tank or radiator and simultaneous increase in the oil level in the pallet. The oil takes the color from gray to milk-white. Air leakage through the carburetor indicates a malfunction of the intake valve, and through the silencer - the exhaust. Detected faults eliminate.
The reason for the reduction of compression in the engine cylinders with good laying of the block head and valves is the wear of the cylindroport group. The degree of wear of the cylindrophone group, which means its technical condition, is determined without disassembly of the engine with devices and a pneummexter. The principle of operation of the instruments is based on the measurement of air leakage supplied to the engine cylinder. Verification is performed on a warm engine. Candles tweaked, set the piston of the first cylinder into the upper dead point of the end of the compression tact. The crankshaft slow down from turning, turning on the transmission and installing the car on parking brake. Press the test tip of the device to the candle hole of the first cylinder, the air supply valve is open and the pressure leakage is determined by the air leakage of the pressure gauge on the instrument. Turning the crankshaft, similarly check other cylinders in accordance with the order of their work. Air leakage should not exceed 28% with serviceable valves and laying the block head.
If the engine of the knocks and noise is uncharacteristic, the engine is listened to the engine with a membrane or electronic stethoscope. The rod of the stethoscope is mounted perpendicular to the surface of the engine in the place where knocks and noises listened.
The state of the piston and the piston finger is determined by a sharp change in the rotation frequency of the crankshaft, listening to the walls of the cylinder block along the piston movement line in places corresponding to its extreme positions. The head of the piston finger is distinct and sharp and disappears when the cylinder is turned off from work. When wearing conjugation piston ring - The piston ganker listens to the mesmer knocker in the bottom of the ground point in the middle speed of the crankshaft. Worn pistons publish when working with a cold engine, clicking a rattling cut-off sound, decreasing as heated.
The wear of the native bearings and an increase in the gap between the crankshaft crankshafts and the liners are accompanied by a deaf metal sound of low tone with a frequency increasing with an increase in the rotational speed of the crankshaft. The knock is listed at the bottom of the cylinder block along the crankshaft axis with a sharp opening of the throttle. The reason for this knock may also be too early ignition. The large axial clearance of the crankshaft contributes to the appearance of a knocking of a sharper tone with uneven intervals, especially noticeable when a smooth increase and decrease in the rotational speed of the crankshaft. The tone of this sound changes depending on whether the clutch pedal is pressed. The size of the axial gap is determined by disabled Engine By moving the front end of the crankshaft when pressed and released the clutch pedal and compare with data from the table.
The connecting rod bearings with wear create a knock as well in the zone of the crankshaft axis, but below or higher by the radius of the crank and when the piston is position in the upper or lower dead points. At the same time, the knock is listening to a sharper and ringing, less power in relation to the knocking of indigenous bearings. The knock disappears in each of the cylinders when it is turned off from the work of the corresponding spark plug.
The sign of the wear of indigenous and connecting rod bearings is also a drop in oil pressure in the engine lubricant system below. Oil pressure is tested by a control manometer with a division price of not more than 0.05 MPa.
Engines with listed faults are directed to the repair.
Brake fluid, like others lubricantsrequires periodic replacement. This is due to loss of qualities, during operation is lost. Thus, the process of replacing the brake fluid on Chevrolet Lacetti is quite simple.
Videos
The video will tell how to quickly and correctly change the brake fluid in the car, and also tells about the nuances and tricks of the process
Replacement process
The process of changing the brake fluid in the brake system is quite simple. For work, another pair of legs will be required, the key on 10 and pear syringe. The fluid change in all four cylinders can take from 30 minutes to 1 hour, depending on how much car enthusiast is realized in the technique of conducting these works.
We produce the brake fluid replacement in the Chevrolet Lacetti car.
So, the change of fluid also provides for pumping brake system, so we will consider two questions at once in one topic. The sequence of actions aimed at replacing the brake fluid in Chevrolet Lacetti regardless of the year of release and body model:
- For any "fireman", it is recommended to dismantle a minus terminal from the battery.
We unscrew the brake fluid tank cover.
- With the help of pears, we pump out the old liquid from the tank.
Pump the syringe brake fluid, but not all, it is desirable to leave a little on the bottom so as not to bring the system.
- After that, we pour a new liquid into the tank, and proceed to pumping the brake system.
We take a new liquid and pour to the MAX mark.
- Since the contours of the brake system are diagonally, the pumping scheme is as follows:
Go down and remove the wheel.
- Rear left.
- Front right.
- Rear right.
- Front left.
- Now, it is necessary to clean the fitting for pumping the brake system from dirt and other unwanted items. And then, dismantle the rubber protective cap of the fitting.
We remove the rubber protective case. We dress up a hose for the brake fluid plum fitting.
- Attention! Do not clean the fitting with a metal brush or similar objects so as not to damage the cap. It is best to use a wet cloth.
- Take the key to 10 and weaken the tightening of the fitting.
- We put on the fitting the tube, and the other end we send to the container where the old brake fluid will flow.
We drain the liquid together with air bubbles in the pre-prepared container and tighten the bleeding fitting.
- Swing the brake pedal 3-4 times with an interval of 1-2 seconds. At the same time, the air can go with the liquid. After pumping, we drag the fitting and then let go. We do so several times until the old liquid comes out from the contour.
During the drain of the liquid, we pay attention to the color and descend until the net brake fluid goes. Thus, pump all the wheels. Then remove the hose, install the wheel back.
- Important! In the process, it is necessary to monitor the level of the brake fluid in the tank. If the liquid is dropped, below the minimum mark, there is a chance to "deliver" the system.
Then check the level of brake fluid in the tank, if necessary, we fill up to the MAX mark. And proceed to another wheel, according to the pumping scheme.
- We carry out such a procedure with each cylinder.
Having done the pumping procedure and topping the DVG on all wheels, once again check the level in the tank (if you need to pour). Then we twist the cover on the brake fluid tank. Replacement is completed.
After the work, it is necessary to spin the fitting and put on the rubber protective cap.
Liquid selection
In addition to the original brake fluid, also in Chevrolet Lacetti, you can pour domestic Dotros-4. It has a lower cost and in composition is a little worse, but on that mileage on which, it is recommended to fill it, for the brake system - it is demolished.
According to the manual for the operation and repair of Chevrolet Lacetti issued by the manufacturer, the shift of the brake fluid is worth spending every 30,000 km of run. If the car is operated in the period of frost or rain, the replacement of the fluid should be carried out every 20,000 km of run.
There are many disputes on how much fluid is necessary for full replacement in the brake system. According to the manuals of the GM plant in both contours, 0.5 liters of brake fluid are closed. When replacing part of the lubricant is lost, so it is recommended to take 1 liter to make sure.
Output
Replace the brake fluid in Chevrolet Lacetti on one side simply, especially those who have already conducted such a process. A newcomer This procedure may seem quite complicated for understanding, and even more so for execution, so in this case it is recommended to contact the car service.
Attention! When operating a car with a trailer and frequent trips to mountain roads Brake fluid must be replaced every 15,000 km of mileage.
Work performed on the viewing ditch or overpass.
Pump the old tank liquid with a syringe or rubber pear.
Pour a new liquid into the tank.
It is necessary to pump the hydraulic drivers of the brake system and the clutch until the new liquid (brighter than the old one) fails to leave the bumps of pumping of all workers cylinders.
Replacing the brake hydraulic fluid
Pumping for the replacement of fluid, we carry out when the engine is not working first on one contour, and then on the other in the following sequence:
- brake mechanism of the right rear wheel
- brake mechanism of the left front wheel
- brake mechanism of the left rear wheel
- brake mechanism of the right front wheel.
Pumping brakes spend with an assistant.
Cleaning from mud shocking the brake mechanism of the right rear wheel.
Remove the protective cap from the fitting.
The assistant should vigorously press the brake pedal until it stops 1-2 times and keep it pressed.
The keyproof key "on 10" turns out the compartment fitting by 1/2-3 / 4 turns.
At the same time, liquid will flow out of the hose, and the brake pedal should be harvested until it stops.
As soon as the liquid stops flowing out of the hose, wrap the fitting, and only after that the assistant can let go of the pedal.
We repeat this operation until a new brake fluid comes from the fitting (brighter than old).
We remove the hose, wipe the bleeding fitting and put on it a protective cap.
Remove the protective cap from the bleeding mechanism of the left front wheel.
I wear a hose on the fitting, and its free end is immersed in the container, partially filled working fluid.
Pouring, as described above, the brake mechanism of the left front wheel, turning the pumping fitting with the "10" key.
Similarly, pump the brake mechanisms of another contour.
When pumping, you need to follow the level of fluid in the tank and add liquid.
Replacing the fluid of hydraulic clutch
We carry out work with the assistant.
Before pumping, check the fluid level in the tank on the main brake cylinder. If necessary, plunge the working fluid.
Remove the protective cap from the pumping fitting.
The key "On 10" weakened the tightening of the pumping fitting, holding the tube adapter with the "19" key.
We put on a transparent hose on the fitting, the other end of the hose is lowered into the container, partially filled with the working fluid, so that the free end of the hose is immersed in the liquid.
Capacity is desirable to set below the level of the fitting.
The assistant presses several times on the clutch pedal and holds it down.
When the clutch pedal is pressed, we turn into 1/2-3 / 4 turnover of the pumping fitting. In this case, the liquid is displaced into the container. Holding the pedal pressed, wrap the fitting and repeat this operation until the new brake fluid go out of the fitting (brighter than old).
Remove the hose and put on the fitting the protective cap.
After pumping the hydraulic drives of the brakes and the clutch, bring the fluid level in the tank to normal.
There is an even simpler version of the brake fluid replacement. This method does not require the presence of an assistant. In this method, some brake fluid supply is desirable (at least 1 liter).
We establish a car on the viewing ditch or the overpass and provide a free passage between the tank with the brake fluid in the pumproom space and brake cylinders of all wheels.
Pump a rubber pear or a syringe brake fluid from the tank. Take a new liquid to the upper edge. To accelerate the process (in order to produce liquid from all cylinders at once), it is desirable to choose four cuts of tubes that wear all cylinder pumps tightly. The free ends of the tubes are lowered into transparent bottles of a small container.
We turn out the fittings of all brake cylinders. We are convinced that the liquid flowed over all four tubes. Control the decrease in the liquid from the tank located on the brake cylinder, and immediately replenish the tank. We observe the rise of the level of liquid in bottles located near the wheel brake cylinders.
It is necessary to move several times from the position of the observation of the fluid from the brake cylinder fittings to the position when you can check and replenish the fluid level in the tank located on the brake cylinder to prevent the tank drainage.
Usually the fastest level increases in the bottle, which is lowered the hose coming from the front left wheel brake cylinder. As soon as in the bottle of the front left wheel, about 200 ml of fluid will turn out, we wrap and tighten the fitting of this cylinder. Next, we wait for the same result at the front right wheel cylinder and also wrapping his pumping fitting. You can complete the process after a 200-250 ml of liquid will be released through the fitting of each rear wheel.
We are convinced of a hermetic tightening of all fittings. Wear protective caps. We specify the level of fluid in the tank of the main brake cylinder.
