How to replace the rear brake cylinder of Wuling car

lz, looking for 4S points, it's only been a year. lz, there are a lot of car maintenance articles on the Internet, the basic maintenance methods are almost the same, copy a better car maintenance article on the car maintenance network for your reference, there are other car details of the maintenance article, if lz needs to see, I will not copy. 1. Check the engine oil level

Park your vehicle on a level pavement. Pull out the vernier ruler to check the oil quantity to ensure that the oil quantity is within the normal range of the two reticle lines (f) and (l). 2. Check the engine coolant level

When the engine is in a hot state, never open the radiator cover. After the engine cools down, check that the liquid level of the coolant should be between full and low, otherwise distilled or purified water should be added (mineral water cannot be added) or refrigerant liquid. If you notice that the coolant decreases quickly in a short period of time, you should check the cooling system for leaks or go to the repair station to check it.

3. Check the brake fluid level: If the brake fluid is close to the lower limit or lower than the lower limit, it means that there may be leakage in the system or excessive wear of the brake shoes, and you should go to the maintenance station for maintenance in time. When adding brake fluid, pay attention to adding the same type of brake fluid to prevent damage to the leather bowl, and pay attention to protecting the paint to prevent corrosion.

4. Check the liquid level of the clutch master pump: the liquid level of the clutch is normal between the high and low liquid levels. If it is difficult or impossible to gear in the engine running state, please overhaul it immediately.

5. Check the tires: check the tire pressure at room temperature every month, and if it is lower than the normal standard, the tire pressure should be replenished in time. Check the cracks of the tires, and replace the tires in time when there are potential safety hazards.

When choosing tires, they should be of the same type. 6. Check the belt: it needs to be adjusted according to the normal standard.

If the belt is aged, it needs to be replaced. 7. Check the air filter: If there is less dust and the blockage is light, you can use high-pressure air to blow it from the inside to the outside and continue to use it.

Dirty air filters should be replaced in a timely manner. 8. Check the spark plug: if any abnormality is found, the gap needs to be adjusted or the spark plug should be replaced.

9. Check the gasoline filter: If the oil supply is found to be poor, check whether the gasoline filter is blocked, and replace it in time if the foreign matter is blocked.

The maintenance problem is very technical, you need to remove the wheel brake drum, and you have to pay attention to adding brake fluid when replacing, etc., it is strongly recommended to go to the maintenance station to replace, and it is a great safety risk if you have not replaced it.

The brake master cylinder of Wuling Pure Light is connected to the brake fluid.

The tube is also connected to the brake to make the Yefeng car oil reservoir, and both of these need to be removed to remove the brake master cylinder, and the specific operation steps are as follows

1. Extract the brake fluid from the brake master cylinder reservoir.

2. Disconnect the oil pipe joint on the outside of the brake master cylinder.

3. There is also a tubing joint at the root.

4. Remove the fixing screws connecting the brake master cylinder and the vacuum booster.

5. There is another one on the other side.

6. Pull outward to remove it.

7. Install the new master pump in reverse order.

8. The installation of restored parts is completed.

To change the brake master cylinder of Wuling Light, one person opens the oil outlet pipe on the master cylinder, and the other person steps on the brake, like a normal four-wheel brake oil, and then drains back to the oil pipe when it is almost discharged, and then the four-wheel one can be discharged.

The specific steps are as follows:

1. Wuling light lamp opens the door of the cab.

2. Step on the Wuling light brake pedal and prepare to start the engine.

3. Press the one-key start button of Wuling lamp.

4. All the instrument lights of Wuling Light are on to prove that the engine has started.

5. Remove the nut at the top of the Wuling Light brake master cylinder.

6. Press the brake pedal to the end, lift it up again, and repeat this action more than 10 times to discharge the air from the Wuling Light brake master cylinder.

In the case of ensuring the normal operation of the brake pump and the exhaustion of the air in the pipeline, the first is to check that there must be a gap of 1 mm between the ejector rod of the vacuum booster and the brake master cylinder. The second is to check the working condition of the rear wheel brake self-adjusting mechanism, when the work is out of balance, there will be this phenomenon.

There is also a car with a proportional distribution valve, when the air is exhausted, pull the handbrake and reload the car or open the proportional valve, which has achieved the best effect.

That's a hassle.

It's better to find a maintenance worker.

Under the steering wheel, you need to lower the steering wheel and lift the instrument panel.

If the car brake cylinder is hydraulic, it cannot be adjusted.

The main function of the automobile brake cylinder is to push the brake pads (rubbing against each other with the brake drum), so as to have the effect of braking. If the sub-pump is broken, it will naturally have a great impact. Although there are no lights on to indicate whether there is damage, you can judge whether there is damage through the feedback effect when braking.

When the brake is pressed, if you feel that the texture of the brake is obviously soft, and the stability of the continuous brake pressing is reduced, it may be that the piston seal of the brake master cylinder and sub-cylinder is poor, or the brake line is ruptured somewhere, resulting in oil leakage. At this time, it is necessary to observe whether there are traces of brake fluid.

Look at whether the sub pump is pneumatic or hydraulic. Air brakes are OK, but hydraulic brakes are not.

The usual structure of air pressure is relatively simple, and the common faults are leakage of leather bowls, weak or broken springs, etc., which are convenient for inspection, adjustment and maintenance;

The brake structure of hydraulic pressure should be complex, the precision requirements of the components are also high, and it is difficult to adjust the sub-cylinder itself, mainly for maintenance, such as cleaning, grinding the piston, replacing the sealing ring, etc., plus cleaning or replacing the brake oil pipe and replacing the brake oil, so as to restore the function and requirements of the brake sub-cylinder.

However, in practice, 4S will not provide a repair kit for the sub-pump (usually a pair of repair kits is only a dozen or tens of yuan), and if there is a problem with the sub-pump, it will be replaced entirely.

The brake cylinder can be repaired or replaced, and now there are cylinder repair kits for sale (the physical store may be because of the profit problem, only selling the pump assembly, not selling the repair kit, but there are repair kits sold online, **only about 30 yuan).

No. You can check to see if there are other problems.

1. Remove the half-shaft bolts, take off the half-shaft, support the wheels, remove the liquid and hollow shaft filial piety bolts, and take off the half-side bearings and wheels together.

2. Remove the brake pads, remove the oil pipe of the brake cylinder, and remove the brake pump.

3. Install the brake pump, install the brake pads and wheels (pay attention to the installation of the piston rods at both ends of the cylinder, install the half shaft, loosen the deflating screw, repeatedly press the brake pedal to deflat, tighten the deflation screw, and rotate the wheel to debug the brake. Until appropriate.

Replacing the brake master cylinder of Wuling Light requires certain skills and experience, if you do not have relevant experience, please go to a regular car repair shop for replacement.

The following are the general steps to replace the liquid lead envy of the Wuling Light brake master cylinder:

Material: New brake master cylinder.

Brake fluid. Steps:

1.Stop and hang the car, open the hood, and locate the original master cylinder, noting that the fluid level is lower than the upper edge of the master cylinder.

2.Remove the original brake master cylinder and turn off the switch.

3.Disassemble the original master pump from the pipe and wire connection, and there are many ways to connect the external connection compacted, pay attention not to let the pipe and wiring fall to the ground after loosening, which is easy to affect the suspension height.

4.Remove both screws, taking care not to damage the spacer with the mounting port. Remove the original master cylinder and place it aside.

5.Install a new brake master cylinder.

6.Connect the pipe and wire, pay attention to eliminate the alarm bubbles, pay attention to do not try to step on the brake for a short time when the brake fluid flows into the main pump, and pinch the orifice of the pump body first. The hydraulic fluid is written to have a default tightening torque. Please use a torque converter for installation.

7.If there are still air bubbles after replacement, you need to vent it. Method:

Find the exhaust hole, connect with the booster pipe, put brake fluid in the gas cup and open the mouth slightly, gently press the brake pedal several times, and release the valve until no bubbles spray out before the foot is completely released each time, and then ** full of oil. The exhaust hole of some models is more biased, easy to block, and it is necessary to insist on slowly emptying, if it cannot be discharged, it is necessary to adjust the angle or put a longer brake to connect the pipe to the inside of the pump body.

8.The owner can open the engine cover to observe whether the replaced master pump has ratchet implementation, ball number and other data are consistent, and then close the hood. Restart the vehicle and test if the brakes are working.

Dear Kiss is very happy to serve you Wuling Rongguang rear brake cylinder after the replacement of the leakage is mostly caused by the oil pipe is not installed properly caused by the oil leakage, remove it and reinstall it to solve the oil leakage. The brake cylinder is an indispensable part of the braking system, its main role is to push the brake pads, and the brake pads rub the brake drum to reduce the speed of the vehicle and stop the combustion. After the brake is pressed, the master cylinder generates a thrust to press the hydraulic oil to the cylinder, and the piston inside the cylinder begins to move under hydraulic pressure to push the brake pads.

The oil brake is made up of a brake master cylinder and a brake fluid reservoir. They have a brake pedal attached to one end and a brake oil leather trouser tube at the other. The brake master cylinder is stored with brake fluid, and there are oil outlets and oil inlets.

When the brakes are applied, the oil outlet opens and the oil inlet closes. Under the pressure of the piston of the pump body, the brake oil pipe is squeezed out of the oil pipe and flows to each brake cylinder for braking function. When the brake plate is released.

The oil outlet in the brake master cylinder will be closed, and the oil inlet will be opened, so that the brake fluid will flow back from each brake cylinder to the brake master cylinder and return to the original state. Withstanding.

1. Depending on whether the sub-pump is pneumatic or hydraulic, the air brake can be adjusted, but the hydraulic one cannot be adjusted;

2. The usual structure of pneumatic fiber is relatively simple, and the common faults are leakage of leather bowls, weak or broken springs, etc., which are more convenient for inspection, adjustment and maintenance;

3. The hydraulic brake structure should be complex, the precision requirements of the components are also high, and it is difficult to adjust the sub-cylinder itself, mainly for maintenance, such as cleaning, grinding the piston, replacing the sealing ring, etc., plus cleaning or replacing the brake oil pipe and replacing the brake oil, so as to restore the functions and requirements of the brake sub-cylinder.
