S-TYPE FRONT BRAKE ROTOR REMOVAL

2001 Jaguar Other

I have a loud squeeling on the front brakes of my Jag. Inspection revealed that the pads & rotors are glazed over. I roughed up the pads but when I tried to remove the caliper bracket, I could not determine the method to do so. Normally there are two bolts that hold the caliper bracket to the control arm, but in the case of the Jag, there is one lower bolt and then it APPEARS that it might be a dowel that goes into the control arm and may need heated.
What should I do?

FRONT DISC BRAKE CALIPER
WARNING: Brake dust, if inhaled can damage your health. Always remove brake dust using a vacuum brush. Do not use a compressed air line to disperse brake dust into the atmosphere.

NOTE: Special tool required: Brake Pedal Holding Tool (JDS 9013). See Fig. 38.

NOTE: Replace brake pads in sets only. DO NOT mix semi-metallic and non-metallic pads.

Removal - Front (Brembo)
Open engine compartment hood and fit paint protection covers to fenders. Raise and support vehicle. Remove wheels.
The following must be carried-out to minimize brake fluid loss when disconnecting the brake hose.
Connect bleed tubes and containers to the left front and left rear caliper bleed nipples. See Fig. 9.
Open left front and left rear caliper bleed nipples.
Using the Brake Pedal Holding Tool (JDS 9013), depress and hold down brake pedal until the brake pedal is held 2.4" (60 mm) down from its released position. Adjust the brake pedal holding tool by rotating adjusting wheel. See Fig. 10.
Close left front and left rear caliper bleed nipples. Remove bleed tubes and containers.
Remove union bolt from the caliper line and discard sealing washers. See Fig. 11. Remove line from caliper and install plug into caliper and line.
Remove the " R" clips from the brake pad retaining pins, remove pins and anti-rattle spring from caliper. Remove disc brake pads. See Fig. 6.
CAUTION: Only remove the bolts securing the caliper anchor bracket to the hub carrier. DO NOT loosen any other caliper bolts.

Remove front caliper mounting bolts and remove caliper from vertical link. See Fig. 12.
Clean and inspect all associated parts.
Installation
CAUTION: Retracting the caliper piston may cause the fluid reservoir to overflow. Remove brake fluid spillage immediately from paint work with clean water. Check condition of the brake pad retaining pins and " R" clips. Replace as necessary.

Install caliper to vertical link. See Fig. 12. Install caliper mounting bolts and tighten to specification. See TORQUE SPECIFICATIONS.
Remove plug from caliper hose port. Slowly retract caliper pistons into caliper. Install brake pads into caliper. Position the anti-rattle spring, install brake pad retaining pins and " R" clips. See Fig. 6.
CAUTION: The brake caliper line must only be installed with the vehicle's body supported and the suspension hanging. It is important that the brake line is aligned correctly when installed to the caliper to prevent it from interfering with the steering and suspension components.

Using NEW sealing washers, install brake caliper line and union bolt. After installation, the brake caliper line must be aligned 20 degrees from the center line of the caliper. See Fig. 13. Tighten line in proper position and to specification. See TORQUE SPECIFICATIONS.
Remove the brake pedal holding tool.
Install wheels. Install lug nuts and tighten to specification. See TORQUE SPECIFICATIONS. Make sure that all brake lines are routed correctly. Lower vehicle.

Removal - Front (Except Brembo)
CAUTION: A New brake hose must be installed when replacing a front brake caliper. The brake pad adhesive backing must not be reused, therefore always install NEW brake pads, irrespective of the condition of the original pads when replacing a brake caliper.

Open engine compartment hood and fit paint protection covers to fenders. Raise and support vehicle. Remove wheels.
The following must be carried-out to minimize brake fluid loss when disconnecting the brake hose.
Connect bleed tubes and containers to the left front and left rear caliper bleed nipples. See Fig. 14.
Open left front and left rear caliper bleed nipples.
Using the Brake Pedal Holding Tool (JDS 9013), depress and hold down brake pedal until the brake pedal is held 2.4" (60 mm) down from its released position. Adjust the brake pedal holding tool by rotating adjusting wheel. See Fig. 10.
Close left front and left rear caliper bleed nipples. Remove bleed tubes and containers.
Unscrew the brake line union, remove the caliper hose lock nut and remove the caliper hose from bracket. See Fig. 15. Fit a plug to brake line to prevent fluid loss.
Unscrew caliper hose and remove hose from caliper. See Fig. 16. Fit a plug to caliper port and discard caliper hose.
Remove the anti-rattle spring from the caliper. Remove dust covers from the guide pins and remove the guide pins. Remove the caliper from its mounting and secure aside. See Fig. 7.
Remove brake pads from caliper housing and discard brake pads. See Fig. 8.
Remove the caliper carrier mounting bolts and remove the carrier from the vertical link. See Fig. 17.
Clean and inspect all associated parts.
Installation
CAUTION: Retracting the caliper piston may cause the fluid reservoir to overflow. Remove brake fluid spillage immediately from paint work with clean water.

Install caliper carrier to vertical link. See Fig. 17. Install caliper carrier bolts and tighten to specification. See TORQUE SPECIFICATIONS.
Remove plug from caliper hose port. Slowly retract piston into caliper housing.
Remove paper backing from pads to reveal adhesive shim. Install brake pads, insert clip located on back of inner pad into caliper piston. See Fig. 8.
Align and install caliper housing to carrier. See Fig. 7. Install and tighten guide pins to specification. See TORQUE SPECIFICATIONS. Install dust covers and anti-rattle spring.
NOTE: The brake hose must only be installed with the vehicle's body supported and the suspension hanging in the straight ahead position.

Install the caliper hose to the caliper. See Fig. 16. Tighten the caliper hose to specification. See TORQUE SPECIFICATIONS.
NOTE: Make sure the brake hose does not twist when tightening the caliper hose lock-nut.

Position the caliper hose thread through bracket and install the caliper hose lock nut. Tighten lock nut to specification. See TORQUE SPECIFICATIONS. Install and tighten brake line-to-caliper hose union nut to specifications.
