CAUTION: TRW and Continental Teves calipers are
not interchangeable. Each caliper is specifically
designed for the unique brake system. If calipers
are interchanged, improper performance, noise and
increased stopping distance can occur.
The two different brake calipers use different
devices to control rattling. While the TRW brakes use
spring clips that mount at the ends of the shoes in
the adapters, Continental Teves brakes use a clip on
the rear of the inboard pad to hold it to the piston
and a larger clip on the outside of the caliper, holding
it to the adapter (Fig. 7).
All brake caliper adapters mount to the steering
knuckle in the same way using two mounting bolts.The brake rotors are also different depending on
brake system. The TRW (disc/drum) front brakes uti-
lize an inverted-hat style rotor. This rotor is exter-
nally vented meaning the inner most diameter of the
braking disc vents to the outboard side (or face) of
the rotor (Fig. 8). The Continental Teves (disc/disc)
front brakes utilize the familiar internally-vented hat
style rotor. Internally-vented refers to the fact that
the inner most diameter of the braking disc vents to
the inboard side of the rotor (Fig. 8).
CAUTION: Do not mix rotor types on the same vehi-
cle. If brake rotors are mixed, noise and wear prob-
lems can result.
DESCRIPTION - DISC BRAKES (REAR)
There are several distinctive features to the rear
disc brakes on this vehicle (Fig. 9). The single piston,
floating caliper rear disc brake system includes a hub
and bearing assembly, adapter, rotor, caliper, and
brake shoes.
This vehicle is equipped with a caliper having a 42
mm (1.65 in.) piston and uses a 15 inch solid non-
vented brake rotor. The brake rotor is described as a
drum-in-hat style because of its dual role as a brak-
ing disc and parking brake drum.
The parking brake system on vehicles equipped
with rear disc brakes consists of a small duo-servo
drum brake mounted to the caliper adapter and uses
the interior of the rear disc brake rotor as a drum
(hat section of drum-in-hat style brake rotor).

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 performance, noise and
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
should be taken not to cross thread the caliper
