Changing disc brakes on the 2003 Jaguar X-type is a simple process that takes less than two hours to do for all four tires, on average. This process only has to be done every three to six years, depending on the brand and quality of the brakes that are on the car. How do you know when it is time to change the brakes if it happens so seldom? The two main signs of brake wear include a squealing or grinding sound as you stop or drive and brakes that grab when you use them.
Loosen all of the lug nuts on the front tires with the tire iron. Place the wheel chocks behind the rear tires. Place the car in park, but do not set the parking brake.
Position the floor jack beneath the axle of the car and jack it up until there is two inches of clearance between the ground and the tire. Place the jack stands underneath the same axle to support the car. Remove the lug nuts and the tire and set them aside.
Remove the bottom restraining bolt on the brake caliper mounting bracket with the socket wrench. The mounting bracket is the half-moon shaped bracket located directly behind the tire, on the rotor. Hang the bottom half of the bracket up in the wheel well with the rope to remove and strain on the brake line.
Remove the brake pads from the bracket by pulling them out by hand.
Compress the brake caliper cylinder using the C-clamp. Position the C-clamp so that the stationary end is against the rear of the bracket and the movable end is pressed against the brake caliper. If the clamp slips off of the caliper, put one of the old brake pads between the clamp and the caliper for added hold. Compress the caliper until it is flat against the back of the bracket.
Set the new brake pads into their place in the bracket. The pads are universal, as far as which side of the bracket they go on. Use one boxed set per wheel and make sure that the black brake material of the pads faces towards the rotor.
Untie the bottom half of the bracket and bolt it back onto the rotor. Bolt the tire back on with the lug nuts, but only tighten them by hand or the wheel will spin. Lower the vehicle and then tighten the lugs with the tire iron.
