Install and tigh

ten bolts to 140 Nm.

5. CAUTI
ONS:
Always install new brake pads, irrespective of the condition
of the original pads, when renewing brake discs.
Retracting the caliper piston may cause the fluid reservoir
to over-flow. Remove brake flui d spillage immediately from paint
work, with clean water.
Note the condition of pins and 'R' clips and replace if
necessary.
Install brake pads in to caliper housing.
Sl

Rear
Disc Brake - Rear Disc Brake
Description an
d Operation

The brake disc is mounted on the wheel studs and is clamped between the wheel and hub. Cooling ducts run through the
center of the brake disc to provide the required ventilation to keep the disc cool under operating conditions.
The caliper carrier, which is se cured to the hub carrier by two bolts, carries the single-piston caliper housing. The caliper
housing is secured to the caliper carrier by two guide-pins and an anti-rattle spring. When the brakes are applied the
caliper-housing piston pushes th e brake pad in front of it, towards the brake di sc. This movement forces the caliper housing
to move along the guide-pins, in the oppo site direction of the piston, to apply the second brake pad. The brake disc is
therefore gripped between the two pads. As brake pressure is increased the grip on the brake disc is increased to slow-down
the rotation of the road wheel.
The disc brakes requ ire no adjustment.

CAUTI O
N: The Brembo caliper is aligned to
the brake disc when it is first installed to the vehicle, therefore, care must
be taken not to disturb this alignment. When removing the ca liper; remove the bolts that secure the anchor bracket to the
hub carrier only. DO NOT loos en any other caliper bolts.
Brembo calipers and discs provide higher -performance braking using the existing hydraulic braking system. The brakes are
installed to the vehicle using unique hub carr iers, hubs, hydraulic hoses and disc shields.
The rear brake disc is a single piece co nstruction which is ventilated and cross-drilled. The disc is mounted on the wheel
studs and is clamped between the wheel and hub. Cooling ducts run through the ce nter of the brake disc to provide the
required ventilation to keep the disc cool under operating conditions.
Modified disc shields are installed to accommodate the larger diameter discs.
Due to the use of fixed calipers in place of the standard floating caliper, certain lateral dimensions on the hub carriers and
hubs are critical to achieve correct cleara nce and operation of the brakes. Therefore special hub carriers and hubs set within
a certain tolerance are inst alled with Brembo brakes.
The four cylinder brake caliper is rigidly attached to the vert ical link via an anchor bracket. The caliper is a split assembly
with each side of the caliper, housing two pistons. The two-pairs of opposed pistons act direct ly on the brake pads mounted
one each side of the disc.
