4. Remove the mounting bo
lts, if equipped with single piston caliper or the
circlip and pin, if equipped with dual piston ca liper. Inspect the bolts for
corrosion and replace as necessary.
5. Remove the caliper fr om the steering knuckle an d suspend it from the body
of the car with a length of wire. Do not allow the caliper to hang by its hose.
6. Remove the pad retaining springs and remove the pads from the caliper.
7. Remove the plastic sleeves and the rubber bushings from the mounting bolt
holes.
8. Obtain a pad replacem ent kit. Lubricate and install the new sleeves and
bushings with a light coat of silicone grease.
9. Install the retainer spring on the i nboard pad, if equipped with single piston
caliper.
A new spring should be included in the pad replacement kit.
10. Install the new inboard pad into the caliper with the wear sensor at the
leading end of the shoe duri ng forward wheel rotation.
11. Install the outboard pad into the caliper.
12. Use a large pair of slip joint plie rs to bend the outer pad ears down over the
caliper, if equipped with t he single piston caliper.
13. Install the calip er onto the steering knuckle. Tighten the mounting bolts to
21-35 ft. lbs. (28-47 Nm), if equipped. In stall the wheel and lower the car. Fill
the master cylinder to its proper le vel with a good quality brake fluid.
14. Pump the brake pedal slowly a nd firmly 3 times with the engine running
before attempting to move the vehicle; bleed the brakes as required.
BRAKE CALIPER

CAUTION - Some brake pads contain asbest os, which has been determined to
be a cancer causing agent. Never clean the brake surfaces with compressed
air! Avoid inhaling any dust from any brake surface! When cleaning brake
surfaces, use a commercially available brake cleaning fluid.

4. Position the brake pads
into the caliper. Lubricate and install new bushings,
sleeves and check valve.
5. When installing the inner brake pad, make sure that the D-shaped tab of the
pad engages with the D-shaped notch of the piston, as illustrated.
6. Upon installation of the inner pad, make sure that the wear sensor of the pad
is at the leading edge of the shoe during forward wheel rotation. Slide the
metal edge of the pad under the ends of the dampening spring and snap the
pad into position against the piston.
7. Install the outer pad and caliper. Afte r installing the caliper, apply the brakes,
then bend the ears of the out er pad against the caliper and ensure that there
is no excessive clearance.

4. Position a C-clamp a
nd tighten until the piston bottoms in the base of the
caliper housing. Make sure 1 end of the C-clamp rests on the inlet fitting bolt
and the other against the outboard disc brake pad.
It is not necessary to remove the parki ng brake caliper lever return spring to
replace the disc brake pads.
5. Remove the upper caliper guide pin bolt and discard.
6. Rotate the caliper housing. Be careful not to strain the hose or cable conduit.
7. Remove the disc brake pads.
To install:
8. Clean all residue from the pad guide surfaces on the mounting bracket and
caliper housing. Inspect the guide pins for free movement in the mounting
bracket. Replace the guide pins or boot s, if they are corroded or damaged.
9. Install the disc brake pads. The out board pad with insulator is installed
toward the caliper housing. The inboard pad with the w ear sensor is installed
nearest the caliper piston. The wear sens or must be in the trailing position
with forward wheel rotation.
10. Rotate the caliper housing into it 's operating position. The springs on the
outboard brake pad must not stick through the inspection hole in the caliper
housing. If the springs are sticking thr ough the inspection hole in the caliper
housing, lift the caliper housing and make the necessary corrections to the
outboard brake pad positions.
11. Install a new upper cali per guide pin bolt and tight en to 26 ft. lbs. (35 Nm).
Tighten the lower caliper guide pin bolt to 16 ft. lbs. (22 Nm).
12. With the engine runni ng, pump the brake pedal slo wly and firmly to seat the
brake pads.
13. Check the caliper parking brake levers to make sure they are against the
stops on the caliper housing. If the leve rs are not on their stops, check the
parking brake adjustment.
14. Remove the 2 wheel nuts from t he rotor and install the wheel and tire
assembly.
15. Lower the vehicle, che ck the master cylinder fluid level and road test the
vehicle.

VALVE LASH

All models utilize a hydraulic valve lifter system to obtain zero lash. No periodic
adjustment is necessary. An initial adjustm
ent is required anytime that the lifters
are removed or the valve tr ain is disturbed. This procedure is covered in Engine
& Engine Overhaul .

IDLE SPEED AND MIXTURE ADJUSTMENTS

Mixture adjustments are factory set and sealed; no adjustment attempt should
be made, except by an aut horized GM dealer or reputable shop equipped with
the necessary equipment.

IDLE SPEED
2-BBL CARBURETOR
WITHOUT AIR CONDITIONING
The engine must be running in "Closed Loop" mode (engine fully warmed) when
making all idle speed adjustments. In this mode, the oxygen sensor affects
control of the fuel delivery.
1. Refer to the emission label on the vehicle and prepare the engine for
adjustments (set the timing). Remove the air cleaner and set the parking
brake. Connect a tachometer to the distributor connector.
2. Place the transmission in DRIVE for automatic transmission, or
NEUTRAL for manual transmission; make sure that the solenoid is
energized.
3. Open the throttle slightly to allow the solenoid plunger to extend. Adjust
the curb idle speed to the specified rpm by turning the solenoid screw.
4. De-energize the solenoid by disconnecting the electrical lead.
5. Set the basic idle speed rpm by turning the idle speed screw. After
adjustment, reconnect the solenoid electrical lead.
6. Remove the tachometer and install the air cleaner.
