1. Siphon
2/3 of the brake fluid from the ma ster cylinder reservoir. Loosen the
wheel lug nuts and raise the car. Remove the wheel.
2. Position a C-clamp across the caliper and press on the pads. Tighten it until
the caliper piston bottoms in its bore.
If you haven't removed some brake fluid from the master cylinder, it may
overflow when the piston is retracted.
3. Remove the C-clamp.
There are 2 different calip ers being used, a single pist on or dual piston design.
The single piston design uses either an Allen head bolt, regular bolt or Torx®
head bolt to secure the caliper to the mounting bracket. Do not use a socket in
place of the Torx® socket, otherwise damage to the bolt may occur. The dual
piston caliper uses a slide pin and ci rclip to secure it to the bracket.

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.

Avoid inhaling any dust from
any brake surface! When cleaning brake surfaces,
use a commercially available brake cleaning fluid.
1. Remove
2/3 of the brake fluid from the mast er cylinder. Raise the vehicle and
remove the wheel.
2. Place a C-clamp across the caliper, positioned on the brake pads. Tighten it
until the piston is forced into its bore.
3. Remove the C-clamp. Remove the bolt holding the brake hose to the caliper.
4. Remove the Allen head caliper mounting bolts. Inspect them for corrosion
and replace them if necessary. Remove the caliper.
To install:
5. Position the caliper with the brake pad installed and install Allen head caliper
mounting bolts. Mounting bo lt torque is 21-35 ft. lbs. (28-47 Nm.) for the
caliper.
6. Install the bolt holding the brake hos e to the caliper and tighten to 18-30 ft.
lbs. (24-40 Nm.).
7. Fill the master cylinder with brake fluid.
8. Install the wheels and lower the vehicle.
CAUTION - Before moving the vehicle, pump the brakes several times to seat
the brake pad against the rotor
OVERHAUL
Some vehicles may be equipped dual piston calipers. The procedure to
overhaul the caliper is e ssentially the same with t he exception of multiple
pistons, O-rings and dust boots.
1. Remove the caliper from the ve hicle and place on a clean workbench.
CAUTION - NEVER place your finger s in front of the pistons in an attempt to
catch or protect the pistons when applying compressed air. This could result in
personal injury!
Depending upon the vehicle, there are two different ways to remove the piston
from the caliper. Refer to the brake pad replacement procedure to make sure
you have the correct procedure for your vehicle.
2. The first method is as follows: a. Stuff a shop towel or a block of wood into the caliper to catch the piston.
b. Remove the caliper piston using co mpressed air applied into the caliper
inlet hole. Inspect the piston for scor ing, nicks, corrosion and/or worn or
damaged chrome plating. The piston mu st be replaced if any of these
conditions are found.

16. Install the caliper in the vehicle.
17. Install the wheel and tire assembly , then carefully lower the vehicle.
18. Properly bleed t he brake system.

BRAKE DISC (ROTOR)

CAUTION - Some brake pads contain as
bestos, 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.

Avoid inhaling any dust from
any brake surface! When cleaning brake surfaces,
use a commercially available brake cleaning fluid.
1. Remove the caliper by following instru ctions of caliper removal procedure.
2. Remove dust cap, cotter pin, castle nut, thrust washer and outside wheel
bearing. Pull the disc/hub assembly from the steering knuckle.
To install:
3. Position the disc/hub assembly to t he spindle/steering knuckle. Install the
outside wheel bearing, thru st washer and castle nut. Tighten the castle nut
until the bearing is s nug. Back off the nut
1/4 turn. Refer to Suspension &
Steering for details on wheel bearing remo val, installation, and adjustment.
Install a new cotter pin and dust cap.
4. Install the brake caliper.
INSPECTION

GM – CAMARO 1982-1992 – Repair Guide (Checked by WxMax) 92
1. Check the rotor surface for wear, sco
ring, grooves or rust pitting. Rotor
damage can be corrected by refacing, cons ult your local garage or machine
shop. If the damage exceeds the minimu m thickness, which is stamped on
the rotor, replace the rotor.
2. Check the rotor parallelism at four or more points around the circumference,
it must not vary more than 0.0005 in . (0.013mm). Make all measurements at
the same distance in from the edge of the ro tor. Refinish the rotor if it fails to
meet specification.
3. Measure the disc runout with a dial indicator. If runout exceeds 0.004 in.
(0.10mm), and the wheel bearings are okay (runout is measured with the
disc on the car), the rotor must be refaced or replaced.

BRAKE DRUMS
REMOVAL & INSTALLATION
CAUTION - Brake shoes may 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.
1. Raise and support the car.

GM – CAMARO 1982-1992 – Repair Guide (Checked by WxMax) 93
2. Remove the wheel or wheels.
3. Pull the brake drum off. It may be nec
essary to gently tap the rear edges of
the drum to start it off the studs.
4. If extreme resistance to removal is encountered, it will be necessary to
retract the adjusting screw. Knock out the access hole in the backing plate
and turn the adjuster to retract th e linings away from the drum.
5. Install a replacement hole co ver before reinstalling drum.
6. Install the drums in the same position on the hub as removed.
DRUM INSPECTION
1. Check the drums for any cracks, scores, grooves, or an out-of-round
condition. Replace if cracked. Slight scores can be removed with fine emery
cloth while extensive scoring requires turning the drum on a lathe.
2. Never have a drum turned mo re than 0.060 in. (1.524mm).
BRAKE SHOES

ADJUSTMENT
Rotate the star wheel adjuster until a sl ight drag is felt between the shoes and
drum, then back off 12 clicks on the adjusting wheel. Put the car in reverse and,
while backing up, apply the brakes seve ral times. This will allow the self-
adjusters to complete the adjustment.
