Brake Caliper: Description and Operation
Front
FRONT BRAKES
Two-piston Caliper
Single-piston Caliper
Each brake disc is made of cast iron. The disc is integral with the hub in the earlier version, but is a separate component in the later version. A splash
shield is used to help keep the disc clean. The brake caliper is mounted on the wheel spindle.
The pad thickness can be measured in the case of the single-piston caliper, using a sliding callipers to measure the distance between points A and B.
This measurement must not exceed 35 mm (1.38 in.) in the case of a normally worn disc.
The pad thickness can also be measured on Girling two-piston calipers, on cars produced after 1, January 1988.
