Front brake disc - inspection, removal and refitting
Note: Before starting work, refer to the warning at the beginning of Section 2 concerning the dangers of asbestos dust.
1 Fully apply the handbrake then loosen the front roadwheel bolts. Raise and support the front of the vehicle on safety stands (see “Jacking and Vehicle Support”) and remove the roadwheel(s).
2 Examine the surface of the disc. If it is deeply grooved or scored or if any small cracks are evident, it must either be refinished or renewed. Any refinishing must not reduce the thickness of the disc to below a certain minimum (see “Specifications”). Light scoring on a brake disc is normal and should be ignored.
3 If disc distortion is suspected, the disc can be checked for run-out using a dial gauge or feeler blades located between its face and a fixed point as the disc is rotated (see illustration).

4 Where the run-out exceeds the specified figure, renew the disc.
5 With the roadwheel removed (see paragraph 1), proceed as follows.
6 To remove a disc, unbolt the caliper anchor bracket, withdraw it and tie it up to the suspension strut to avoid strain on the flexible hose (if necessary, remove the brake pads as described in Section 2) (see illustration).
