How does the new Civic rear brake system have tightropes, and what is that?

1. Analysis of possible causes.

1. It is the lack of necessary maintenance of the brake system, there are too many impurities in the brake master cylinder, the sealing is not tight, the vacuum booster pump fails, the brake oil is too dirty or the air resistance occurs after the mixing of several brake oils after heating, the brake master cylinder or sub-cylinder leaks, and the air leakage of the gas tank or pipeline interface;

2. It is due to improper operation that causes the failure of the parts;

3. Due to serious overload, under the action of gravitational acceleration, the inertia of vehicle movement is increased, which directly leads to brake failure.

Second, the treatment method.

1. Control the direction according to the road conditions and speed, disengage the high-speed gear, and at the same time quickly blast the empty fuel and shift the high-speed gear into the low-speed gear. In this way, the engine will have a lot of traction resistance and the speed of the vehicle will be reduced rapidly. In addition, the handbrake should be used in conjunction with the low-speed gear shift, but it should be noted that the handbrake should not be tightened or pulled too slowly.

If it is pulled too tightly, it is easy to make the brake disc "lock", and it is likely to damage the transmission parts and lose the braking ability; If it is pulled too slowly, the brake disc will wear and ablate and lose its braking effect.

2. Use the bumper, carriage and other rigid parts of the car to rub and collide with natural obstacles (rocks, trees or soil slopes) on the side of the road to achieve the purpose of forcibly stopping and getting out of danger, and reduce the accident loss as much as possible.

3. If the brake fails when going uphill, it should be reduced to medium and low gear in time to maintain sufficient power to drive uphill to the top of the slope and stop. If you need to park on a half-slope, you should keep the forward low gear, tighten the hand brake, and the personnel with the vehicle should use stones, skids and other objects to jam the wheels in time. If there is a backward slippage, the rear of the car should face the hillside or the safety side, and the headlights and emergency lights should be turned on to attract the attention of the vehicles in front and behind.

4. When the downhill brake fails and the speed of the vehicle cannot be controlled by the mechanism of the vehicle itself, the driver should decisively use natural obstacles, such as rocks and trees on the side of the road, to cause resistance to the car. If you can't find a suitable terrain or object to use for a while, in an emergency, you can move one side of the car closer to the side of the mountain, and gradually reduce the speed of the vehicle by rubbing to increase the resistance.

5. The vehicle should step on the brakes when going down a long slope or a steep slope, regardless of whether there is a situation or not. It can not only test the performance of the brakes, but also buy time to control the speed of the vehicle when the brakes are found to be out of order, also known as predictive braking.

3. Preventive measures.

Do not ignore the daily maintenance of the brake system, in order to prevent the occurrence of brake failure, please maintain the brake system in time, regular maintenance and overhaul is essential, for the safety of life, you must not ignore the regular maintenance.

Note: Check whether the brake shoes are in good condition, and do not overuse the brakes, hang the low gear when going downhill, use the brake of the engine to let the car drive, supplemented by the foot brake; Avoid severe overloading to prevent brake failure.

The Civic is an electronic parking brake, and that steel wire is an electronically controlled brake total. Because of this, the Civic rear brake cannot be directly modified with other calipers.

How to change the rear brake pads of the new Civic ( check the transaction price |How to replace the rear brake pads The replacement method of the Civic rear brake pads is as follows: 1. Before replacing the brake pads, you should first open the lid of the brake fluid reservoir in the engine compartment to see the height of the brake fluid page, if the brake fluid page is above the highest limit, the brake fluid should be sucked out to prevent the brake fluid from overflowing during the replacement process; 2. Prepare the brake pads to be replaced and remove the wheels where the brakes are located. In the process of dismantling, it is necessary to avoid scratches on the rim; 3. Remove the bolts of the brake caliper with a wrench combined with the sleeve, and then remove the brake pad (if there is a brake induction line, the brake induction line should be removed first).

Observe whether the brake pads are overworn, or cracked, and replace them in the next step; 4. Since there will be a lot of sand or mud in the brake caliper, it should be cleaned with a rag, and then applied silencer paste to prevent abnormal noise when braking; 5. Press the piston to the position where the piston pressure pump cannot be pressed, then install the brake pads on the brake caliper, install the new brake pads in place (those with brake induction lines should also be installed), tighten the guide bolts, and the installation is completed; 6. After installation, cover the lid of the liquid storage tank, enter the car and press the brake pedal a few times, and reset the brake. Then observe the height of the brake fluid, which should be within the appropriate height range; 7. Test drive after changing to check whether the braking effect is reflected. @2019

Civic brake discs are available in front and rear. There is no specific replacement cycle for Civic brake discs. When the mileage of the vehicle reaches 100,000 km, the brake disc of the vehicle should be checked. If it is damaged or worn to the limit, it should be replaced in time.

Follow these steps to replace the brake disc:

1.Check the degree of wear of the wide Zen brake disc. During normal maintenance, there is no need to replace the brake disc. According to the actual situation, judge whether to replace the brake disc. The brake disc has a notch of more than 3 mm and can be replaced.

2.Remove the front tire. To replace the brake discs, remove both front tires. You can see that the disc is the car brake disc.

3.Remove and grip the bush fixing brake caliper screws. The brake discs are mounted on the front wheel bearings and are held in place by brake calipers on the outside. Remove the two 18 screws on the wrong brake and remove the brake caliper. Because there is an oil pipe connection on the brake caliper, lower it slowly to prevent the oil pipe from breaking.

4.Remove the old brake disc. The old brake discs were mounted on the front wheel bearings, which caused rust on the bearings and brake discs.

At this time, you can use a hammer to tap from behind the brake disc, and turn the brake disc as you knock, so that all four sides of the brake disc can be tapped. After a few taps, you can remove the old brake disc.

5.Install new brake discs. After aligning the eyelets of the new brake disc with the eyelets on the bearing, gently tap the inside of the brake disc with a hammer so that it is completely fixed on the bearing;

6.Install brake calipers with caution. Install the brake caliper in its original position, tighten the two set screws, and use the rotating bearing to observe whether there is any abnormal noise during rotation.

Method steps.

Before replacing the brake pads, you should open the brake fluid reservoir lid in the engine compartment and check the height of the brake fluid page. If the brake fluid level exceeds the maximum limit, you should suck out some brake fluid to prevent the brake fluid from spilling during the replacement process.

Prepare the brake pads to be replaced and remove the wheels where the brakes are located. Avoid scratching the rim when disassembling.

Use a wrench and sleeve to remove the bolts of the brake caliper, and then remove the brake shoe (if there is a brake induction line, take the Heki to remove the brake induction wire first). Observe the brake pads for excessive wear or cracking, and if so, replace them in the next step.

Since there will be a lot of sand or mud in the brake caliper, it needs to be cleaned with a rag and then applied with noise reduction paste to prevent abnormal noise during braking.

Use the piston pump to press the piston to a non-lifting movable position, and then install the brake pads to the caliper. After the new brake pads are installed in place (if there is a brake induction line, they should also be installed), tighten the guide bolts and the installation is complete.

After installation, close the reservoir lid and press the brake pedal several times to reset the brake. Then observe the brake fluid height, which should be within the appropriate height range.

After replacement, a test run is carried out to check whether the braking effect is reflected.
