Handbrake Caliper:
5. Bend down locking tabs securing handbrake caliper mounting bolts, then remove mounting bolts, tab washer and retraction plate.
6. Remove caliper by sliding to the rear, around the brake disc. When the caliper is at the rear of the disc, reposition it toward the middle of the suspension unit and remove it out the bottom.
NOTE: The calipers should be checked for proper self-adjusting operation, before they are refitted to the car.

Handbrake Pads:
REFIT
1. If new pads are fitted or caliper has been overhauled, adjust caliper by holding one carrier and rotating the other, until a dimension of approximately 0.75 in (19 mm) between pad surfaces, is reached. This will assist in refitting. Be sure of pad orientation.
2. Place caliper into rear suspension unit. Long carrier arm should be on inside of brake disc.
3. Slide caliper up around brake disc and position into mounting bracket.
4. Check mounting holes with a mirror for alignment.
5. Fit retractor and recheck alignment with mirror.
6. Fit tab washer plate and threaded mounting pins. Be sure the pins engage the caliper holes. (It is easy to miss one!) It is recommended that the short carrier pin is engaged first.
7. Tighten mounting pins and bend lock tabs.
8. Operate caliper lever(s) several times to adjust pad clearance.
9. Reconnect return springs and cable.
