Checking the brake disc and brake components
Check for corrosion, wear and tear on the inner walls of the cylinder. If necessary, replace the cylinder body. Minor flaws caused by corrosion or foreign particles, remove the grinding surface with fine emery cloth. Check for corrosion, wear and tear on the surface of the piston, the guide finger, anther guide pin and the brake disc. If necessary, replace the faulty components.
| Fig. 6.39. Marking the hub bolt and the brake disc
|
Mark the screw wheel and the brake disc before removing for installation (Fig. 6.39). Remove the bolt and remove the brake hose. Remove the cover of the guide pin and the pin itself.
| Fig. 6.40. Measuring thickness of a brake disk
|
Using a micrometer, measure the thickness of the brake disk (Fig. 6.40). The standard thickness of 26 mm. The minimum thickness of 24 mm. Replace the disc if the disc thickness is less than the minimum allowable. Fasten the brake rotor to the wheel hub wheel nuts (twice or more).
Measuring point: - At a distance of 10 mm from the outer edge of the disc. Maximum runout: 0.05 mm or less.
ATTENTION Prior to measurement ensure that the axial clearance is 0 mm. |
If a significant beating, find minimum runout point sequentially shifting the installation position of the brake disc on the hub on one hole. Remove rust or dirt from the contact surface of the brake disc and wheel hub. Install the brake disc and align the marks made before removal.
