We know that the car is before the "physical condition"
Some abnormal behavior will be used to attract the attention of the owner
Remind the owner to repair it in time
For example, when the brakes are weak, difficult to step on, offset, and abnormal
This may be a precursor to a "brake failure"
Ignoring these "red flags" will have dire consequences
Today we will analyze these 4 "red flags" about brakes
Help everyone to do it, early understanding of early maintenance and early safety!
The brakes are weak
The weakness of the brakes is mainly manifested in the feeling that the vehicle cannot be stopped when pressing the brakes
Or the braking time is significantly longer than before
This failure is mostly caused by the loss of pressure on the transmission line
At this time, you should go to the special store for the staff to check
The brake master pump is located at the interface of the leather relief pipe and the engine
Whether there is cracking or loosening
If the situation is not right, it needs to be repaired and replaced in a timely manner
The brake pedal is difficult to step on
The brake pedal is difficult to step on and divided into two situations: the pedal is "hard" and "soft"
The brakes are both high and hard, and it is difficult to start or travel hard, that is, "the pedal is hard"
It may be that the check valve in the vacuum air receiver in the brake boost system is broken
If the vacuum is not reached, the brakes will be stepped on hard
In this case, it is necessary to replace the relevant accessories in time
"Pedal weakness" means that the braking force is abnormally weakened
There are usually three causes for this failure
? The oil pressure of the brake sub-pump or the total pump is not enough, and there may be oil leakage;
? Brake failure, such as damage to brake discs, brake discs, etc.;
? Brake lines enter the air. If you press the pedal continuously, the height of the pedal is slightly increased and elastic, indicating that it has penetrated into the air.
At this time, you should also go to the special shop for maintenance inspection by the staff
Avoid hazards due to brake failures when driving
(Replace brake)
Brake offset
When the vehicle is about to brake, one side will stop first
The direction is deflected, which is commonly known as "brake offset"
This is mostly because the left and right sub-pumps of the brake system do not act evenly on the brake pads
Or the degree of wear of the brake pads on both sides is inconsistent
Causes uneven braking force, resulting in "brake offset"
At this time, the brake sub-pump should be replaced
Or when changing the brake pads on a daily basis, they should also be replaced together on both sides
(Replace the brake sub-pump)
There is an abnormal noise when braking
When the brakes are slammed, a sharp metallic friction sound is emitted at the brake pads
Especially in rainy and snowy weather, it occurs frequently
This is generally due to the thinning of the brake pads, which leads to increased friction with the brake discs
Or the brake pad material is poor caused
Check the brake pad thickness first
If the naked eye observes the thickness of the brake pads, only 1/3 of the original remains
It is time to replace the brake pads
Learned about the 4 major red flags before the brakes fail
If the owner's friend finds a suspicious situation when driving
You should be vigilant and go to the special store as soon as possible for corresponding inspection and maintenance
But if the brakes fail, how do we treat it calmly?
Stay calm, hold the steering wheel while turning on the dual flash to alert passing vehicles, lower gears, and use engine brakes to slow down. When using a mechanical handbrake, avoid one-time tensioning, and the rear wheel is easily locked. If an electronic handbrake is installed, it is recommended to leave it on until it slows down. If the brakes fail at high speed, in addition to the above operations, the vehicle can also be driven into the emergency avoidance lane, and the ramp buffer can be used to reduce the speed until it is safe.
