4E – 18IREAR DISC BRAKES
DAEWOO V–121 BL4
GENERAL DESCRIPTION
AND SYSTEM OPERATION
DISC BRAKE CALIPER
The caliper has a single bore and it is mounted to a bracket
on the wheel knuckle. Hydraulic pressure, which is trans-
mitted to the piston and the caliper, is created by pressing
the brake pedal. During braking, the piston and the caliper
apply a clamping force on the brake shoes. The vehicle is
stopped as a result of the friction between the rotor and the
brake shoes.
S When servicing a caliper, replace all parts included
in the caliper repair kit.
S During caliper overhaul, lubricate the piston and the
inner seal with clean brake fluid to ease assembly.
S Do not use lubricated shop air on brake parts be-
cause oil will deteriorate rubber seals.
S If any hydraulic component is removed or discon-
nected, it may be necessary to bleed all or part of
the brake system.
S Replace the shoes in axle sets only.
S The torque values specified are for dry, unlubri-
cated fasteners.
S Perform the service operations on a clean bench
away from oily material.
