JH.9 - CALIPER OVERHAUL
The front brake calipers are manufactured by A.P. Racing, and are to be dismantled or overhauled only by
their factory at Wheeler Road, Seven Stars Industrial Estate, Coventry, CV3 4LB.
The Brembo rear brake calipers may have the sliding pins overhauled as detailed below, but any signs of
hydraulic leakage from the cylinder indicate that the unit should be replaced.
Rear Caliper Sliding Pins
The sliding bushes and sleeves of the Brembo rear calipers may be replaced without disturbing the hydraulic
connection:
a) Disconnect the parking brake cable from the caliper.
b) Remove the cap head bolt securing the bottom guide bush to the caliper adaptor plate.
c) Remove the hex. head bolt securing the top guide bush to the caliper adaptor plate, and withdraw the
caliper from the car with the brake hose still connected.
d) Slide out the lower steel guide sleeve and withdraw the bush/boot from the caliper. Pull the boots off the top
steel guide bush and slide out the bush from the caliper.
e) Clean the guide bores in the caliper body with brake cleaner. Lubricate the new bushes and boots with
silicone grease provided in the repair kit, and reassemble into the caliper in reverse order to disassembly.
f) Refit the caliper to the adaptor plate using Permabond A134 on the threads of both bolts, torque tightening
the two fixings to:
Upper M10 bolt; 45 - 50 Nm (33 - 37 Ibf.ft)
Lower M8 caphead; 26 - 30 Nm (19 - 22 Ibf.ft)
g) Reconnect the parking brake cable and operate the footbrake to reposition the pads before driving the car.
