General Description
Front Disc Brake Caliper Assembly Construction
S6JB0B4201001
This caliper is mounted to the brake caliper carrier with two caliper pin bolts. Hydraulic force, created by applying force
to the brake pedal, is converted by the caliper to friction. The hydraulic force acts equally against the piston and the
bottom of the caliper bore to move the piston outward and to move (slide) the caliper inward, resulting in a clamping
action on the disc. This clamping action forces the pads (linings) against the disc, creating friction to stop the vehicle.
For components, refer to “Front Disc Brake Components”.
NOTE
Lubricate parts as specified. Do not use lubricated shop air on brake parts as damage to rubber
components may result. If any component is removed or line disconnected, bleed the brake system.
Replace pads in axle sets only. The torque values specified are for dry, unlubricated fasteners.

Front Disc Brake Pad On-Vehicle Check
S6JB0B4206002
Inspect pad linings periodically according to
maintenance schedule whenever wheels are removed
(for tire rotation or other reason). Take a look through
hole of caliper and check lining thickness of outside and
inside pads.
If one of brake pad is worn to service limit, all linings
must be replaced at the same time.
Front brake pad thickness “a”
Standard: 11.0 mm (0.43 in.)
Limit: 2.0 mm (0.08 in.)
Front Disc Brake Pad Removal and Installation
S6JB0B4206003
NOTE
When replacing brake pad, replace it on the
right and left.
Removal
1) Hoist vehicle and remove front wheel.
2) Remove caliper pin bolts (2).
3) Remove caliper (1) from caliper carrier.
NOTE
Hang removed caliper (1) with a wire hook (2)
or the like so as to prevent brake hose from
bending and twisting excessively or being
pulled. Don’t operate brake pedal with pads
removed.
4) Remove pads (3).
Installation
1) Install pad spring (1), shims (6) and pads (2) to
caliper carrier (4).
NOTE
Install brake pad with wear indicator (5) to
vehicle center side on right wheel brake.
