1 Park your car on a level surface. If you have a stick shift car make sure the car is in gear. Place blocks in front of the front tires so the car does not move while you are working on it.
2 Open the hood of your car and locate the master cylinder. If necessary, remove brake fluid until the level in the container is less than half full. A turkey baster is a good tool for this. Put the brake fluid in the plastic container and dispose of it the way you dispose of motor oil.
3 Raise the rear end of your car with your car jack. Remove the rear tire or wheel assembly.
4 Remove the parking brake cable from the back of the caliper. Use the pliers to remove the cable clip (restraining clip). This step is done only for Grand Prix RPO Z7Us.
5 Hand-tighten two lug nuts to the studs to hold the disc rotor in place while you work on the caliper. Remove the bolt and washer holding the cable support bracket to the caliper. The cable support has the parking brake cable and brake hose attached to it. This step is not done for Grand Prix RPO Z7Us.
6 Use the socket wrench to remove the caliper guide pin bolts. Slide the caliper off of the disc rotor and hang it in the wheel well with a small bungee cord or wire hanger; Don't let the caliper hang from the brake hose.
7 Remove the brake pads and shims from the caliper. Throw away the shims.
Install the new Brake Pads
1 Use the spanner tool to rotate the piston clockwise all the way into the caliper. Make sure the notches on the piston are at the 6 and 12 o'clock positions. There is a boot (rubber seal) around the piston bore. Lift the seal's inner edge and press out any trapped air. Insert the brake pad clips into the caliper support.
2 Apply a thin coat of lubricant to the parts of the inner pad that come in contact with the caliper piston and mounting areas. As you install the brake pads in the caliper support, make sure the wear sensors are downward and at the leading edge of the rotor when the tire rotates. Push the brake pads into the support, holding the metal shoe edge against the spring end of the pad clips. This slightly bends the spring ends and lets the notches engage with the support. This step does not apply for the Grand Prix RPO Z7U.
3 Swing the caliper back into place over the brake pads and replace the mounting bolt. Reconnect the cable support bracket and tighten the bolt to 32-ft.lb. (43 Nm). Remove the lug nuts holding the rotor in place. For the Grand Prix RPO Z7U, Slide the caliper back into place on the disc rotor. Reconnect the parking brake cable. Insert and tighten the caliper mounting bolts to 44 foot lb. (60 Nm).
4 Replace the tire wheel assembly. Lower the car to the ground.
5 Pump the brake pedal a few times to seat the brake pads. Do this before trying to move your car.
6 Add fluid to the master cylinder container to replace any you removed before you removed the old brake pads.
7 Season the brake pads by making only gentle stops when you are driving for the first week
Remove wheel, remove the two bolts in the calipers, pull up calipers, remove pads compress caliper piston with a c-clamp, be sure to have the brake fluid cap off the reservoir under the hood. pull the rotor off and put the new one on. - replace pads and reverse the order.
Not hard at all. Just lift car, take wheel off. Spot the Caliper. Take the two guide pins (bolts) out and slide the caliper off the pads. Pull both old pads off and replace them with the new ones. Place brake grease on the outside of the pads where the calipers push on them or they will squeek badly. Use a C-clamp or a break tool (that you can borrow from AutoZone) to push the caliper piston back in so it will fit over the new pads (while doing this, watch the break fluid resivoir as you may need to take some out so it does not overfill). Then slide the caliper back over the pads. Place some grease on the guide pins and then put them back in. Then put the wheel back on.
Make sure you start the car and pump the breaks until you feel them grab again or you won't have breaks until they do.
Remove the brake master cylinder filler cap and remove fluid until the reservoir is half full.
Raise and safely support the vehicle.
Remove the rear wheel and tire assembly.
CAUTION Never allow the brake caliper to hang from the brake hose.
Remove the two disc brake caliper pin bolts.
Lift the disc brake caliper from the anchor plate and position the caliper out of the way. Do not disconnect the fluid line.
Inspect the disc brake caliper for leaks and replace the caliper if necessary.
Remove the pads and retraction clips.
To Install: CAUTION Do not allow grease, oil, brake fluid or other contaminants to contact the pad lining material.
Install retraction clips.
Install the brake pads.
Slowly compress the caliper pistons with a large C-clamp.
CAUTION Use care not to damage the bleeder screw or front disc brake rotor shield.
Install the disc brake caliper.
Install the disc brake caliper pin bolts. Tighten the pin bolts to 26 ft. lbs. (35 Nm) (F-250, F-350 SRW). Tighten the pin bolts to 56 ft. lbs. (76 Nm) (F-350 DRW). Tighten the pin bolts to 46 ft. lbs. (62 Nm) (F-450 F-550).
Install the wheel and tire assembly.
Lower the vehicle.
Fill the brake master cylinder reservoir with DOT 3 motor vehicle brake fluid.
remove the caliper, by removing the two holding bolts, then use a old brake pad against the pistons and a c clamp and push piston all the way in, next is to clean and lube pad mounting surface and the caliper slide pin, then install new pads on bracket then caliper and tighten caliper bolts, heres a diagram to help you,
On my bonnevile, a c clamp wouldn't work. Online, it identified the calipers need to be turned back in. On the front side, there should be grooves in the center of the caliper that you can turn to retract. to allow enough space for it to go back on.
To remove the caliper, you need a torx head tool (can't remember exact size) to remove the two slide pin bolts.(inside the two small rubber boots at each end of caliper) After getting them loose, remove the brake hose, then remove bolts and caliper. (don't loose the two copper washers...if they aren't in the new caliper box you will need them.) Check and see if the caliper retracts easily after it is removed. If it does, the rubber brake hose may have internally failed and is your problem. If piston is very hard to move, get a new caliper. Replace both side brake pads, not just side you are workingon. (recommend both calipers as well but most times it works fine with one. When replacing, make sure slides are free in calipers and thread pins by hand so that you don't cross thread them. After it's back together bleed front brakes and before moving car step on brake to re-set pistons.
