Several brake pad problems of heavy truck brake pads

1. Abnormal noise when braking

When you step on the brakes, the brake system will make a sharp metal rubbing sound.

This may be caused by the thinning of the brake pads of heavy trucks, potholes in the brake pads, foreign matter in the brake pads or rust on the brake discs, etc. Generally, the abnormal noise of the brake will be alleviated by stepping on a few more feet.

2. The brake pedal stroke becomes longer

The straightforward point can be understood as the brake becomes softer.

The main reasons for the longer brake stroke are air in the brake system, lack of brake fluid, possible leakage, and serious brake pad wear.

3. Brake deviation

The phenomenon of braking deviation is not very common, mainly reflected in the obvious deflection of the steering wheel to one side when the brake is applied.

This phenomenon may be caused by partial wear of the brake pads and a problem with the brake cylinder.

4. The brakes become hard

Many card users will encounter the problem of hardening of the brakes. The main reasons for the hardening of the brakes are the failure of the vacuum booster to cause the brakes to be unassisted, and the brakes are frequently stepped on.

5. Rebound when stepping on the brake

Many card friends have encountered this situation. When the brake is stepped on, the brake pedal rebounds to the top of the foot. This phenomenon is mostly caused by the uneven surface of the brake disc, brake pad, and deformation of the steel ring.

All in all, there are many problems in the brake system. When there is a problem with the brake pads of a heavy truck, it is best to do a simple initial investigation to confirm whether the problem is serious and whether you can continue to drive to the repair shop. Do not ignore the brakes. Safety, because this is related to everyone's safety.
