INSTALLATION
INSTALLATION - FRONT DISC BRAKE CALIPER
(DISC/DISC BRAKES)
CAUTION: TRW and Continental Teves brake cali-
pers are not interchangeable. Each caliper is specif-
ically designed for the unique brake system (TRW -
disc/drum brake combination and Continental Teves
- disc/disc brake combination). If calipers are inter-
changed,
improper
increased stopping distance can occur.
(1) Completely retract the caliper piston back into
piston bore of the caliper. Use a C-clamp to retract
the piston if necessary. Place a wood block over the
piston before installing the C-clamp to avoid damag-
ing the piston.
CAUTION: Use care when installing the brake cali-
per assembly onto the steering knuckle, so that the
seals on the caliper guide pin bushings do not get
damaged by the steering knuckle bosses.
(2) Carefully position the brake caliper and shoes
over the brake rotor and adapter.
(3) Install the caliper guide pin bolts and tighten
to a torque of 35 N·m (26 ft. lbs.). Extreme caution
