- Remove the caliper and rotor, be aware of wheel hub bearing on rotor, and tighten the nuts.
- Inspect rotor surface for uneven wear patterns, deep grooves, high edges, crack, and hot spot.
- Measure rotor thickness. Not less than standard.
- Inspect rotor distortion with a dial gauge.
- Rotors preparation before installation
2.1 Polish rotor surface to remove film transfer between rotors and brake pads surface.
- Resurface rotor in case that it has uneven wear and deep grooves.
-In case of replacing new rotor, the rotor surface should be washed with brake cleaner.
2.2 Clean dust from metal on the rotor surface after resurfacing by polishing rotor with sandpaper and blowing out dust which attach on rotor surface. Then cleaned with brake disc cleaner or water mixed with general cleaning liquid.
2.3 Use a tool to push the piston back into place.
Note the brake fluid level in the reservoir. Not to overflow from the brake fluid reservoir.
3. Brake pads preparation before installation.
3.1 Choose the right brake pads for your car model and driving behavior.
3.2 Inspect brake pads
- Brake pads surface has no dirt attached.
- Brake pads are ready for use.
Inspect the tool for brake pad installing like caliper kit (shim, sound absorbing pads and springs).
3.3 Apply lubricant (brakes grease) on friction points between brake discs, caliper brake and sound absorbing pads.
