Rear brake disc - removal and refitting

Note: Before starting work, refer to the note at the beginning of Section 5 concerning the dangers of asbestos dust.

Removal

1. Slacken and remove the two bolts securing the brake caliper in position. Slide off the caliper and position it clear of the brake disc, taking care not to strain the brake pipe.

2. Release the handbrake then remove the hub grease cap by levering or tapping it off (see illustration).

Remove the nut.

4. Pull the disc/hub unit off the stub axle, catching the washer and the bearing outer race (see illustration). If the handbrake shoes seem to be preventing removal, disconnect the handbrake cable from the lever on the brake backplate.

   On refitting, adjust the hub bearings.
