2. Conduct a disk inspection; deep burrs are not acceptable and the disk requires processing.
3. Make sure that the thickness of the disc meets the operating requirements.
4. Check the axial runout of the disc, which should not exceed 0.12 mm.
5. If necessary, remove the front wheel hub (see Removal, installation and adjustment of the hub and front wheel bearings).
6. Screw two bolts into the hub and clamp the unit in a vice with the brake disc facing up.
7. Using a socket wrench, loosen the bolts and separate the brake disc from the hub.
Note: Clean mating surfaces before installation. New discs have an anti-corrosion paint coating that must be removed with solvent before installing the disc.
8. Install a new one (restored) disc on the hub, tighten the new bolts evenly.
9. Install the hub and brake caliper (see Removal, installation and adjustment of the hub and front wheel bearings and Removal, disassembly and installation of the brake caliper).
Note: The rear brake disc is installed on the flange of the wheel drive shaft, making sure that it fits on the small pin.
