1. NOTES:


Some variation in the illustrations may occur, but the essential
information is always correct.


RH illustration shown, LH similar.


All measurements must be taken with the wheel installed.


2. WARNING: Make sure to support the vehicle with axle stands.

Raise the rear of the vehicle.

3. Modify tool 100-053 with an M8 bolt and nut as shown.
4. Mount the DTI Dial Test Indicator (DTI) gauge on the tool as shown. www.JagDocs.com

7. Position the DTI probe in the centre of the disc.
Zero DTI and rotate road wheel one complete
revolution to measure disc runout.























8. Position the DTI probe 5 mm from the inner edge of the
disc.
Zero DTI and rotate road wheel one complete
revolution to measure disc runout.


















9. NOTE: The disc runout limit is 0.09 mm.

If the disc runout exceeds the limit check the hub drive flange and
bearing runout.
For additional information, refer to: Rear Wheel Bearing and Wheel Hub Runout Check - Vehicles With: High Performance Brakes (204-00 Suspension System - General Information, General Procedures).

10. If hub runout is within the limit replace the brake disc.

ront Disc Brake - Overview

Description and Operation

OVERVIEW

Performance Brakes - 5.0L Supercharger V8 Vehicles
The performance front braking system features ventilated brake discs with dual piston sliding calipers. The discs are 380 mm
(14.96 in.) diameter x 36 mm (1.42 in.) thick.

The brake disc is manufactured from cast iron. The disc is retained on the wheel hub by two retaining washers and the wheel
nuts.
A brake pads wear sensors is fitted to the LH front brake.

BRAKE CALIPERS System Operation

When hydraulic pressure is supplied to the caliper, the pistons extend to force the inner pad against the brake disc. The caliper
reacts and slides along two guide pins to bring the outer pad into contact with the brake disc.

BRAKE PAD WEAR SENSORS

When a brake pad incorporating a brake pad wear sensor is approximately 75% worn, the sensor wire within the pad material
is worn through and the brake pad wear sensor goes open circuit. When the instrument cluster detects the open circuit, it
illuminates the amber LED (light emitting diode) in the brake warning indicator, displays an appropriate warning in the
message center and sounds a warning chime.
Refer to: Instrument Cluster (413-01 Instrument Cluster, Description and Operation).

NOTE: A new pad wear sensor lead must be fitted whenever the brake pads are changed, irrespective of the brake pad
warning sensor being triggered.



BRAKE CALIPERS Component Description

Each caliper is mounted within a fixed carrier that is secured to the front wheel knuckle with two bolts. The inboard brake pad
of the LH (left-hand) brake incorporates a wear sensor.

Each outboard brake pad is installed with a pressed steel anti-rattle spring. On SC (supercharger) vehicles, a badge with the
'R' symbol is formed on the anti-rattle spring.

BRAKE PAD WEAR SENSORS

The brake pad wear sensor is wired in series with a wear sensor on the RH (right-hand) rear brake and the instrument cluster.
If the thickness of one of the brake pads connected to a wear sensor decreases to a predetermined limit, the instrument
cluster illuminates the brake warning indicator.
