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.

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.

1. Remove 2/3 of the brake fluid from the ma
ster cylinder. Raise the car.
Remove the wheel. Reinstall a wheel nut, with the flat side toward the rotor,
to hold the rotor in place.
2. Loosen the parking brake cable at the equalizer. At the caliper, remove the
parking brake cable, damper and spring from the lever.
3. Hold the parking brake lever and re move the lock nut. Remove the lever,
seal and anti-friction washer.
4. Position a C-clamp ov er the caliper and force the piston into its bore.
Remove the C-clamp. Rein stall the lever, seal and nut to the caliper.
5. Loosen the brake tube nut and disc onnect the brake tube from the caliper.
Plug the tube to prevent t he loss of brake fluid.
At the right rear wheel, it may be necessary to remove the rear bolt from the
lower control arm to allow the lower caliper mounting bolt to be removed.
6. Remove the mounting bolts using a
3/8 in. Allen head socket. Remove the
caliper and inspect the mounting bolts for corrosion. If necessary, replace
the mounting bolts.
To install:
7. Place the caliper onto the rotor and install the m ounting bolts. Torque the
mounting bolts to 30-45 ft . lbs. (40.7-61 Nm).
8. Install a new anti-friction washer and lubricate the lever with silicone brake
lube. Install the lever on the actuator with the lever pointing down. Rotate the
lever toward the front of the car and hol d while installing the nut. Torque the
nut to 30-40 ft. lbs. (40.7-54.2 Nm), then rotate the lever back against the
stop on the caliper.
9. Install damper and spring. Connect the parking brake cable. Tighten the
cable at the equalizer until the lever starts to move off the stop on the
caliper, then loosen the adjustment unt il the lever moves back against the
stop.
10. Remove the nut holding the rotor in place and install the wheel. Lower the
car and fill the master cylin der with brake fluid.
1989-92 MODELS
1. Raise and safely support the vehicle.
2. Loosen the parking brake cable at the equalizer.
3. Remove the wheel and tire assembly. Inst all 2 wheel nuts to retain the rotor.
4. Remove the bolt, inlet fitting and was hers from the caliper housing. Plug the
holes in the caliper housing and inlet fitting.
5. Remove the caliper lever return spri ng only if it is defective. Discard the
spring if the coils are opened.
6. Disconnect the parking brake cable from the caliper lever and caliper
bracket.
7. Remove the 2 caliper guide pin holes.
8. Remove the caliper housing from the rotor and mounting bracket.

Some electrical components which require
a large amount of current to operate
use a special switch called a relay. Sinc e these circuits carry a large amount of
current, the thickness of the wire in the ci rcuit is also greater. If this large wire
were connected from the load to the c ontrol switch, the switch would have to
carry the high amperage load and the fair ing or dash would be twice as large to
accommodate the increased size of t he wiring harness. To prevent these
problems, a relay is used.
Relays are composed of a coil and a se t of contacts. When the coil has a
current passed though it, a magnetic fiel d is formed and this field causes the
contacts to move together, completing the circuit. Most relays are normally
open, preventing current from passing thr ough the circuit, but they can take any
electrical form depending on th e job they are intended to do. Relays can be
considered "remote control switches." They allow a smaller current to operate
devices that require higher amperages. W hen a small current operates the coil,
a larger current is allo wed to pass by the contacts. Some common circuits
which may use relays are the horn, headlight s, starter, electric fuel pump and
other high draw circuits.

Fig. 3: Relays are composed of a coil and a switch. These two components are
linked together so that w hen one operates, the other operat es at the same time.
The large wires in the circuit are connect ed from the battery to one side of the
relay switch (B+) and from the opposite side of the re lay switch to the load
(component). Smaller wires are connected from the relay coil to the control
switch for the circuit and from the opposite side of the relay coil to ground
LOAD
Every electrical circuit must include a "load" (something to use the electricity
coming from the source). Without this l oad, the battery would attempt to deliver
its entire power supply from one pole to another. This is called a "short circuit."
All this electricity would take a short cut to ground and cause a great amount of
damage to other components in the circui t by developing a tremendous amount
of heat. This condition could develop suffici ent heat to melt the insulation on all
the surrounding wires and reduce a multiple wire cable to a lump of plastic and
copper.

SERVICE PRECAUTIONS
The DERM can maintain sufficient volt age to cause a deployment for up to 10
minutes after the ignition switch is tur ned OFF or the battery is disconnected.
Always disable the system when perfo rming service procedures ON OR NEAR
the system and it's components.
CAUTION - The disarming and arming procedures must be followed in the
order listed to temporarily disable the SI R system. Failure to do so could result
in possible air bag deployment, pers onal injury or otherwise unneeded SIR
system repairs.
DISARMING THE SYSTEM
1. Turn the steering wheel so that t he vehicle's wheels are pointing straight
ahead.
2. Turn the ignition switch to the LOCK position.
3. Remove the SIR or AIR BAG fuse from the fuse panel.
4. Remove the left side trim panel, t hen remove the Connector Position
Assurance (CPA) device and disconnec t the yellow two-way SIR harness
connector at the base of the steering column.
5. On vehicles with passenger side air bags, remove the glove box door
then disconnect the yellow two-way c onnector located near the yellow
24-way DERM harness connector.
With the fuse removed and the ignition sw itch ON, the air bag warning lamp will
be on. This is normal and does not indicate a SIR system malfunction.
