How to replace the rear brake cylinder of Lechi, the brake becomes soft after changing the brake cyl

Remove the half-shaft bolts, take down the half-shaft, support the wheels, remove the hollow shaft 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.

The reasons may be: there is air in the pipeline, free travel of the pedal or the brake clearance is too large, if the brake is soft, it is recommended to go to the 4S shop to check the specific reason, brake to drain the air, it is best to use a computer detector to discharge the brake air.

The brake master cylinder is also known as the brake master oil (gas), and its main function is to push the brake fluid (or gas) to be transmitted to each brake cylinder to push the piston.

The brake master cylinder is a one-way acting piston hydraulic cylinder, which converts the mechanical energy input by the pedal mechanism into hydraulic energy. There are two types of brake master cylinders, single chamber and double chamber, which are used for single circuit and double circuit hydraulic braking systems respectively.

In order to improve the driving safety of automobiles, according to the requirements of traffic regulations, the service braking system of automobiles now adopts a double-circuit braking system, that is, a dual-circuit hydraulic braking system composed of a series double-chamber master cylinder (single-chamber brake master cylinder has been eliminated).

At present, almost all of the dual-circuit hydraulic braking systems are servo braking systems or power braking systems. However, in some miniature or light vehicles, in order to make the structure simple, under the condition that the brake pedal force does not exceed the driver's physical strength, there are also some models that adopt a series of double-chamber brake master cylinders to form a double-circuit manpower hydraulic braking system.

It has little to do with the brake fluid (it's not black), the main thing is that the oil pipe has air, I teach you how to empty, three people, one step on the brake (step on it for 4 5 seconds, as long as it is slow) one person refueling (the oil level can not be lower than the lower line), one person empty, from 2 to 2 before, release the "fuel injector" and hold the mouth with your hand, step on the brake and have oil spray before the mouth, and then step on the brake to step on the elastic brake, release the oil (end), live on the fuel injector, and then step on the ......Almost the next round is arranged, and after the four rows are finished, the row is repeated again until the oil pressure is very high, and it flies out 20 to 30cm away.

This is generally the case! Exhaust the gas first! Then turning down the four brake clearances will generally solve the problem!

Jianyi, you first change the brake oil, drain the air and then try, and adjust the four wheel cylinders.

The brakes are still not good, so you can consider replacing the brake pads, brake steel hose, etc.

1. Change the set of brake pads.

If you want to improve the braking strength simply and effectively, change to a good brake pad, and the effect is also obvious. Of course, the choice of brake pads is particular, especially can not be used for competitive racing grade brake pads, its design is originally designed for the track, need to have a relatively high car temperature to have enough friction.

Moreover, once the operating temperature is reached, the friction will be very high, and the brakes will be extremely sensitive, which will seriously affect the comfort. In short, these brake pads are not suitable for everyday use at all.

2. Change the brake steel hose.

I feel that the brakes are not good, and many times the brakes feel bad, and it is very soft to step on. In fact, many of the original brake hoses are made of rubber, which is too soft in texture, and it is easy to expand when braking, which has an impact on the foot feel.

The most direct way to improve the foot feeling is to replace the brake steel hose, because of the outer layer of strong wire, this brake tube is not so easy to expand, and the foot feeling will be improved.

However, the installation of this brake steel hose should be very careful, and after installation, it is necessary to check whether there will be scratches in the general direction, otherwise, long-term stretching and extrusion will be prone to the possibility of bursting.

3. Change tires with good grip.

In fact, the most direct impact on the braking distance is the tire, because the car relies on it to touch the ground, and when braking, it also depends on its friction to slow down. Therefore, a good tire can improve the braking performance.

In this way, it may be a simple brake disc, the so-called shrinking car, the brake disc is one size smaller, and the brake caliper is also one size smaller, resulting in insufficient braking force.

Have you read the CCTV report? , Wuhan's taxis are all that total color, how to repair the brake is not good, in the end can only be replaced with a larger braking system to solve the problem immediately.

It depends on what kind of car you have, and what exactly you are looking for, because every car is different. If the old car is recommended to be disposed of manually, if the brake system, maintenance agent, etc. The difference is whether to step on and go down or pedal to step on the brake or not to brake, etc.

This depends on what kind of car it is, since it has changed the exhaust air, not to mention, the most important thing is the quality of the things you change. No more, only to change the car.

If you are sure that your car has no problems with the brake pads and pots, it is recommended to replace the air motorized valve, which is inside the girder box.

Buy a car brake master cylinder, this master cylinder is leaking, want to replace it with a new one, is there one?

Summary. Hello, you said this situation, if the rear sub-pump does not come out, it is generally caused by air in the brake line, you can drain the air to try, and the sub-pump at the front end of the car comes out first, and does not reset later, then there are special tools in this case, and you can press it directly with special tools, this is not a one-way movement.

How to replace the rear brake cylinder of Lechi 09 years after the right rear wheel of Lechi removed the brake pads, the cylinder only relies on the front side of the car to stretch out the distribution after stepping on the brakes, the rear column of the cylinder does not come out, and the pump column near the front end stretches out after the pressure is sold or not reset, is the pump a one-way movement, how to press the column head to recover?

Hello, I'm helping you sort out the answers to your questions, please wait a moment

Hello, you said this situation, if the back of the sub-pump can not come out, in one fell swoop is the brake pipeline in the air bend quietly, you can drain the air to try, and the front end of the sub-pump out first, after not reset, then there are special tools, directly with special tools to press in, this is not a one-way movement.

How to drain hydraulic brake air after installing the brake cylinder of Chevrolet Luxis.

Hello, after the installation of this simplification, the simple discharge method is to step on the brakes by one person, one person at the brake, exhaust at the position of the pump hungry exhaust screw, if there is a special equipment, you can operate it alone, directly with a special rotten bridge vacuum, direct vacuum exhaust can be.

Lechi rear brake cylinder (or brake hydraulic cylinder) is one of the parts of Lechi automobile, and its manufacturer may vary due to region, time and other factors. Therefore, it is not simple which manufacturer produces better quality.

When buying a rear brake cylinder, you can choose from the following aspects:

1.Understand the original parts: The original parts refer to the parts provided by the ** business officially approved by Lechi Automobile. They are considered to be the most compliant products, but they are also relatively expensive.

2.Look for mainstream brands: Some well-known brands usually offer rear brake cylinders with high quality assurance, such as BOSCH, Akebono, TRW, etc.

3.Choose according to the user's evaluation: When purchasing parts, you can understand the quality of the supplier by looking at the evaluations and feedback of other users.

It should be noted that the rear brake cylinder is an important part of the automotive braking system, which directly allows the limb to be related to driving safety, so it is recommended that you be cautious when choosing, ensure that the quality and performance of the selected product meet the standards, and look for a trustworthy supplier to buy.

The inside of the rear brake cylinder of Lechi is always rusty, probably because the sealing effect of the dust jacket is not good. If the brake cylinder is rusted, it should be replaced with a new one. There is no other workaround.

When the driver steps on the brake pedal, the vacuum booster pump will provide a boost, which can help the driver press the brake pedal.

Precautions for use:The process of braking is actually the process of converting kinetic energy into heat energy.

The braking system of the car is a joke that requires the use of brake fluid, which needs to be changed regularly.

Brake fluid is a liquid that absorbs water very easily, and if you don't change it for a long time, it will cause the water content in the brake fluid to be too high.

If the water content in the brake fluid is too high, it will cause the braking force to drop and the braking distance will be extended.

When the amount of water in the brake fluid reaches 3%, the brake fluid should be replaced immediately.

When changing the brake fluid, you should go to a professional institution, find a professional, and use professional equipment to replace it.
