During driving, brake failure is a very dangerous thing. In fact, before the brake failure is not without warning, if you find the following phenomena, you must be vigilant.
Shake when you press the brakes
This situation mostly occurs on old cars, because of the wear of the brake discs/blades, the surface flatness of which is inaccurate to a certain extent, making the steering wheel or body shake when stepping on the brakes.
It is recommended to check the braking system, select the lathe disc process grinding as appropriate, or replace it with a new brake disc/piece.
The steering wheel is off track
This situation is commonly known as "partial braking", which is mainly caused by the uneven action of the left and right sub-pumps of the braking system. When the vehicle brakes, the faster side of the wheel stops first, and the steering wheel will deflect.
If the steering wheel is deviated when the brakes are pressed, it means that there is a hidden danger in the braking system and the sub-pump may need to be replaced.
The brakes soften
When the brakes become soft, the braking force is abnormally weakened, usually due to these three reasons:
1. Oil leakage phenomenon occurs in the sub-pump or the main pump, and the oil pressure is not enough.
2. The brake pads, brake discs, etc. are malfunctioning.
3. There is air in the brake line. If the pedal height is slightly increased during continuous braking and has a sense of elasticity, it means that air has penetrated into the brake line.
Special tips
In addition, the brake pedal is not returned or the return is not timely, which is also a symptom of brake failure, and it must be dealt with in time to eliminate potential safety hazards.
