MALFUNCTION

phenomenon:

Partially burnt friction material (white edge)

the reason:

The brake disc is at a high temperature due to frequent driving or dragging the vehicle

influences:

Reduce the initial braking effect;
Friction material loss is serious;
The material becomes brittle and prone to cracks and debris

solution:


If the phenomenon is not serious, it can be used continuously, and it will not affect the braking efficiency under normal driving conditions;
If the phenomenon is serious, replace the brake pads
phenomenon:

a lot of black silk powder on the surface of the hub

the reason:

When the brake pad is braked, the friction material and the brake disc are strongly rubbed, and the friction material will be the product powder during the rubbing process. Due to the low metal friction formula containing metal fibers, some of the powder adheres to the hub under the action of frictional static electricity.

influences:

In the effective use of the brake pads, it will not affect the normal car safety.

solution:

Clean in time;
Replace the brake pads with better quality
phenomenon:

Friction material contaminated with oil, grease, brake fluid

the reason:

The oil spilled and was stained on the brake pads;
Always driving in oily water

influences:

Motor vehicle side slip phenomenon
Reduce braking effect


solution:

Replace the brake pads
phenomenon:

Steel back damage, bending

the reason:

The installation method is incorrect;

Installation is too hard

influences:

Reduce braking effect, generate noise or tremor;
Calipers may get stuck

solution:

Replace the brake pads
phenomenon:

Single or multiple wear and tear

the reason:

Brake caliper locating pin or piston stuck

influences:

When braking, the vehicle will be deflected
Brake pads wear unevenly and wear out

solution:

Maintenance of the caliper locating pin and piston
phenomenon:

Uneven wear marks or slag on the edge of the brake pad

the reason:

Brake disc wear is uneven

influences:

Noise generated when braking, accompanied by tremor
Severely worn brake pads

solution:

Replace brake pads and brake discs

phenomenon:

There is a crack in the middle of the brake pad

the reason:

The brake caliper is stuck, the brake piston is bent on the steel back, and the steel back is cracked by the friction material.

influences:

Noise when braking
When the brakes occur, the vehicle is deflected

solution:


Replace the brake pads

Maintenance of the caliper locating pin and piston
