Brake disc knowledge

NO.1
Appearance: the brake contact surface of the brake disc is unevenly worn, blue spots appear in its center, and cracks may appear.
Cause: incorrect installation of brake caliper and / or brake pad will lead to inconsistent angle of each brake pad relative to the brake disc and different wear speed of each side. The local severe overheating of the friction contact surface is the cause of blue spots.
Effect: excessive hot spots can cause gradual vibration and may also reduce braking efficiency.

Solution: If necessary, check and repair the brake caliper. Replace the brake pads and check that the type and shape of the new pads match the application.

No.2
Appearance: the small end of the brake disc is torn or broken from the brake surface of the brake disc.
Cause: mechanical stress due to misalignment of brake disc center during assembly. Incorrect assembly or positioning of brake caliper and brake disc leads to continuous asymmetric wear on the brake surfaces on both sides of the brake disc, and finally the small end of the brake disc is torn from the brake surface of the brake disc.
Impact: at the beginning, there will be huge noise and vibration in the braking process. When the small end of the brake disc breaks from the braking surface of the brake disc, it will lead to mechanical failure.

Solution:Thoroughly inspect the brake system and its associated components. Replace all faulty parts, install new brake discs, and tighten the brake discs according to the tightening torque and sequence recommended by the manufacturer. Before installing the brake disc, please check the assembly position of the brake caliper body on the axle

NO.3
Appearance: the contact surface between the brake disc and the wheel hub is deformed and / or cracked around it.
Cause: the tightening torque used for the set screw is too large.
Impact: vibration will occur during braking from the initial braking

Solution:Replace the brake disc and avoid using excessive tightening torque. The set screw is only used for brake disc positioning

NO.4
Appearance: the contact surface between brake disc and wheel hub is deformed or the mounting hole is cracked.
Cause: the tightening sequence of brake disc is incorrect, and the tightening torque used is not enough.
Effect: significant vibration will occur during initial braking.

Solution: Please replace the brake disc and fasten it in the correct installation sequence and according to the torque requirements recommended by the manufacturer
