Brake Caliper: Description and Operation
Rear
REAR BRAKES
Each rear brake disc is made of cast iron and is mounted on the axle shaft. The brake shield helps keep the disc clean. The disc hub also serves as a
drum for the parking brake.
Brake Caliper For Multilink Rear Axle
The caliper is mounted on the bearing housing.
The brake caliper for a multilink rear axle is a sliding, single-piston type of similar design to the Girling single piston front caliper.
The function of the fluid seal is to prevent the escape of brake fluid and to return the piston to the idle position after braking. The seal is square in
section and is pressed against the piston by the slightly angled groove in the housing. The dust seal prevents the entry of dirt between the cylinder and
piston. The pads are held in position between the piston housing and caliper retainer.
Since the left and right-hand calipers are identical, the caliper is provided with two bleeding nipples.
The upper nipple should be used for bleeding purposes.
