2010 JAGUAR XFR hand brake

7. CAUTION: Removal of the clips is a delicate
procedure, damage will occur if any force is used.


NOTE: Left-hand shown, right-hand similar.

Lever the anti-rattle spring in the center of the
spring until either side is released.

















8. WARNING: If the brake caliper piston seal is damaged
a new brake caliper must be installed.


CAUTION: Do not allow the brake caliper to hang on
the brake hose.


NOTE: Left-hand shown, right-hand similar.
















9. NOTE: Left-hand shown, right-hand similar.
Release the clip.

1. WARNING: Do not use compressed air to clean brake components.
Dust from friction materials can be harmful if inhaled.


CAUTION: As the piston is pushed back into the caliper housing,
the brake fluid level in the reservoir will rise. Do not allow the reservoir
to overflow.
Press the piston into the caliper housing.

2.
Apply grease C2C-39930 to the areas indicated.

6. NOTE: Left-hand shown, right-hand similar.

Secure the bottom arm of the anti-rattle spring
under the bottom anchor bracket of the caliper.
Compress the upper spring arm into the correct
position, under the upper anchor bracket, whilst
retaining the logo plate.
Using the screw-driver, tap the central locating tag
into the locked position.
















7. CAUTIONS:


Always plug any open connections to prevent
contamination.


Make sure new sealing washers are installed.

NOTES:


To prevent the loss of brake fluid, using the special
tool apply the brake pedal and set to 40mm ( 1.6 in ) below
the rest position.

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 rear wheel knuckle with two bolts. Each outboard brake pad
is installed with a wire anti-rattle spring.

The brake calipers on SC (supercharger) vehicles are painted and also include a logo badge, secured with two screws, which
must be removed in order to change the brake pads.
The inboard brake pad of the RH (right-hand) brake incorporates a wear sensor.

BRAKE PAD WEAR SENSORS

The brake pad wear sensor is wired in series with a wear sensor on the LH (left-hand) front 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.

Torque: 10 Nm





















6. CAUTIONS:


Always plug any open connections to prevent
contamination.


If brake fluid is spilt on the paintwork, the affected
area must be immediately washed down with cold water.
NOTES:


To prevent the loss of brake fluid, using the special
tool apply the brake pedal and set to 40mm ( 1.6 in ) below
the rest position.
