4. Before refitting the pads, inspect the piston boot for splits, cracks or other damage, and for any signs of fluid
leakage or wetness. If any such signs are apparent, the complete caliper should be replaced as Brembo do
not recommend that this caliper be dismantled.
5. If refitting the existing brake pads, refit each pad in the same position as originally fitted.
6. Before fitting new rear pads, the caliper piston must be screwed back into the caliper down the parking
brake actuation mechanism. This operation requires the use of special tool T000T1242 and the removal
of the brake disc:
Remove the single socket head screw retaining the brake disc, and remove the disc.
Fit special tool T000T1242 into the holes in the caliper piston, and screw the piston back down
the parking brake mechanism screwthread until fully bottomed.
Refit the brake disc, and tighten the countersunk retaining screw to 12 Nm.
7. Slide the brake pads into the caliper. Position the pad anti-rattle spring in the caliper aperture, with t h e
spring ends located in the recesses provided. Ensure that the spring is fitted the correct way up, w i t h
the turned spring end in the longer recess. Press the spring eyes into alignment whilst the pad retaining pin
is inserted through the caliper from the outside. Ensure that the pin passes through both eyes of the anti-
rattle spring, and both brake pads, and that the pin is fully installed with the snap ring seated in the outboard
side of the caliper.

8. Refit the roadwheels and press the brake pedal several times to set the brake pad position. Before switch-
ing on the ignition, check the fluid level in the reservoir and top up if necessary.
9. Ensure the customer is made aware that maximum braking efficiency will be achieved if, for the first few
hundred miles, needless heavy braking is avoided, and the brake pads are allowed to 'bed in' fully before
being used to their full potential.
JH.5 - PARKING BRAKE MECHANISM
Operation of the handbrake lever applies a pull to a short link cable which connects via a horseshoe
compensator to the centre of a single cable linking the two rear calipers. At each caliper, the cable connects to a
lever which operates the hydraulic piston by mechanical means:
Movement of the caliper lever causes rotation of one of a pair of steel discs, rotation of the other being
restrained by a stop bolt in the cylinder. Hardened balls housed in ramps machined in the discs, force the discs
