Front Disc Brake - Front Disc Brake
Description and 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 vertical link by two bolts, carries the single-pis ton 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.

hub are critical to achieve correct clearan
ce and operation of
the brakes. Therefore special vertical links and hubs set within
a certain tolerance are inst alled with Brembo brakes.
The front discs are handed and must be fitt ed to the correct side of the vehicle. The left-hand disc can be identified by a
groove running around the circumference of the outer disc wall as shown in the illustration below.
Left hand disc - identification mark

Modified disc shields are installed to accommodate the larger diameter discs.
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.
Stainless steel hydraulic hoses connect the calipers to the existi ng brake tubes. It is important that these hoses are aligned
correctly when installed to pr event them fouling on the steering and suspen sion components. Refer to operation 70.55.24
for information.
The Brembo disc brakes require no adjustment.

ARNING: BRAKE DUST, IF INHALED CAN DAMAGE YOUR
HEALTH. ALWAYS REMOVE BRAKE DUST USING A VACUUM
BRUSH. DO NOT USE A COMPRESSED-AIR LINE TO DISPERSE BRAKE DUST INTO THE ATMOSPHERE.
• CAUTIONS:
Replacement of nuts and bolts: Various thread-locking de vices are used on nuts and bolts throughout the vehicle.
These devices restrict the number of times a nut or bolt can be used. See section 100-00 for information.
Remove brake fluid spilla ge immediately from paint work, with clean water.
A new brake hose must be installe d when replacing a brake caliper.
The brake pad adhesive backing must not be reused, therefore always install new brake pads, irrespective of the
condition of the original pads when replacing a brake caliper. Always replace brake pads as an axle set.
