1. Raise and support the car. Remove the wheel.
2. Remove the caliper by referring to
the Rear Caliper Removal procedure. Pull
the brake disc from the axle.
3. To install, place the rotor ont o the spindle and install caliper.
4. Install the wheel and lower the car.
INSPECTION
1. Raise and support the car. Remove the wheel. Replace wheel nuts to hold rotor in place.
2. 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.
3. Using a dial indicator, check the ro tor parallelism at several points around
the circumference. The difference must not vary more than 0.0005 in.
(0.013mm). Make all measur ements at the same distance in from the edge
of the rotor.
4. Using the same dial indicator, meas ure the rotor runout. The runout should
not exceed 0.004 in. (0.10mm).
5. If any of these conditions are not me t, reface or replace the rotor.

In the HEI system, as in other electr
onic ignition systems, the breaker points
have been replaced wit h an electronic switch - a tr ansistor - which is located
within the ignition module. This switching transistor pe rforms the same function
the points did in a conventi onal ignition system; it simply turns the coil's primary
current on and off at the correct time. Essentially, electronic and conventional
ignition systems operate on t he same principle.
The module which houses the switching transistor is controlled (turned on and
off) by a magnetically gener ated impulse induced in the pickup coil. When the
teeth of the rotating timer align with t he teeth of the pole piece, the induced
voltage in the pickup coil signals the elec tronic module to open the coil primary
circuit. The primary current then decreases, and a high voltage is induced in the
ignition coil secondary windings, which is then directed through the rotor and
high voltage leads (spark plug wires) to fire the spark plugs.
In essence, the pickup coil module system simply replaces the conventional
breaker points and condenser. The condenser found within the distributor is for
radio suppression purposes only and has nothing to do with the ignition
process. The ignition module automatically controls the dwell period, increasing
it with increasing en gine speed. Since dwell is co ntrolled in this manner, it
cannot be adjusted. The module itse lf is non-adjustable/non-repairable and
must be replaced if found defective.
SYSTEM PRECAUTIONS
Before proceeding with troubleshooting, ta ke note of the following precautions:
TIMING LIGHT USE
Care should be exercised when connec ting a timing light or other pick-up
equipment. Do not force anything between the boots and wiring, or through the
silicone jacket. Connections should be made in parallel using an adapter.
Inductive pickup timing lights are the bes t kind to use with the ignition systems
covered by this information.
SPARK PLUG WIRES
The plug wires used with these systems are of a different construction than
conventional wires. When replacing them, make sure you get the correct wires,
since conventional wires will not carry the voltage. Also, handle the wires
carefully to avoid cracking or splitti ng them, and NEVER pierce the wires.
TACHOMETER USE
Not all tachometers will operate or indi cate correctly when used on an HEI or
C
3I system. While some tachometers ma y give a reading, this does not
necessarily mean the reading is correct. In addition, some tachometers hook up
differently from others. If you cannot fi gure out whether or not your tachometer
will work on your car, check with the tachometer manufacturer.

Fig. 1: Vehicle hoisting and jacking points
Never place the jack under the radiator , engine or transmission components.
Severe and expensive damage wil l result when the jack is raised. Additionally,
never jack under the floorpan or body work; the metal will deform.
Whenever you plan to work under the v ehicle, you must support it on jackstands
or ramps. Never use cinder blocks or st acks of wood to support the vehicle,
even if you're only going to be under it for a few minutes. Never crawl under the
vehicle when it is supported only by the tire-changing jack or other floor jack.
Always position a block of wood or smal l rubber pad on top of the jack or
jackstand to protect the lifting point's finish when lifting or supporting the vehicle.
Small hydraulic, screw, or sci ssors jacks are satisfactory for raising the vehicle.
Drive-on trestles or ramps are also a handy and safe way to both raise and
support the vehicle. Be careful though, some ramps may be too steep to drive
your vehicle onto without scraping t he front bottom panels. Never support the
vehicle on any suspension member (unless specifically instructed to do so by a
repair manual) or by an underbody panel.
JACKING PRECAUTIONS
The following safety points cannot be overemphasized:
• Always block the opposite wheel or wheels to keep the vehicle from
rolling off the jack.
• When raising the front of the vehicle, firmly apply the parking brake.

TRACK BAR BRACE
REMOVAL & INSTALLATION
1. Raise the rear of the vehicle, pl ace jackstands under the rear axle, then
lower the jack so that the stands are supporting all of the weight.
2. Remove the heat shield screw s from the track bar brace.
3. Remove the three track bar brace-to-body brace screws.
4. Remove the track bar-to-body bra cket fasteners and remove the track
bar brace.
To install: 5. Place the track bar brace into position.
6. Install the track bar-to-body bracket fasteners.
7. Install the three track bar brace-to-body brace screws.
8. Install the heat shield scre ws to the track bar brace.
9. Lower the vehicle.
CONTROL ARM
REMOVAL & INSTALLATION
Remove/reinstall only one lower control ar m at a time. If both arms are removed
at the same time, the axle could roll or slip sideways, making reinstallation of
the arms very difficult.
1. Raise the rear of the vehicle, pl ace jackstands under the rear axle, then
lower the jack so that the stands are supporting all of the weight.
2. Remove the control arm attachi ng fasteners, then remove the control
arm.
3. Installation is a simple matter of bol ting the arm into place. Torque the 3
bolts at the body brace bracket to 35 ft. lbs. (47 Nm) and the nut at the
body bracket to 61 ft. lbs. (83 Nm).
TORQUE ARM
REMOVAL & INSTALLATION
The coil springs must be removed BEFORE the torque arm. If the torque arm is
removed first, vehicle damage will result. In order to proceed, the vehicle must
be supported in a manner whic h will allow the rear axle height to be adjusted
independently of the body height.
1. Remove the track bar mounting bolt at the axle assembly, then loosen
the track bar bolt at the body brace.
2. Disconnect the rear brake hose clip at the axle assembly, which will allow
additional drop of the axle.
3. Remove the lower attaching nuts from both rear shock absorbers.
4. Disconnect the shock absorbers from their lower attaching points.
