For brake caliper removal and installation, start off by following the process as outlined in the pad removal procedure, but in addition to it you need to take the brake hose-to-brake caliper retaining bolt and the brass washers are to be discarded and while plugging the brake hose and the brake caliper bolt hole. Check the condition of the brake caliper, piston as well as the rubber seals and replace if there is any defects on them. If the brake pads were removed, put them back onto the brake caliper and then follow installation of the brake caliper as described above for brake pad installation, but always use new sealing washers when fitting the hose to the brake caliper. Put a new sealing washer in the brake hose, slide the bolt through the hose fitting, put a second sealing washer, put the hose/bolt to the brake caliper and tighten the bolt to the range of 22-29 ft.lb. After installation let the brake system go through the brake bleeding process to ensure that the brake system is not leaking and is fully operational. If the overhauling of the brake caliper is required, then it should be detached from the vehicle so that it can be placed on the workbench but when blowing with compressed air, one should ensure that fingers are not placed in front of the pistons. Depending on the vehicle, there are two methods to remove the piston: One of them is to use a shop towel or a wooden block to support the piston when blowing compressed air into it, the other is to turn the piston counterclockwise so that it retracts. If the vehicle has an anti-rattle clip, then it should be unscrewed and then using a pry tool, the brake caliper boot and piston seals must be detached from the groove of the brake caliper bore. Twist the brake bleeder valve cap and valve from the brake caliper housing: examine the inside of the brake caliper bores, pistons and the mounting threads for signs of scoring or excessive wear. Remove light corrosion with crocus cloth, remove all dirt from all parts with denatured alcohol and evacuate with compressed air. For assembly of the brake calipers, you are supposed to lubricate and fit the bleeder valve and cap, fit new sealing material into the grooves for brake caliper bore, lubricate the piston bore, fit the pistons and boot in the brake calipers and then push them to the bottom of the bores. There should be use of suitable driving tool to position the boots in the housing and then place the brake caliper in the vehicle after which you fit the wheel and the tire assembly, then lower the vehicle well and then properly bleed the brake system.

Apply the parking brake and block the wheels opposite the end being worked on. Loosen the wheel lug nuts, raise the vehicle and support it securely on jackstands. Remove the wheel. Unscrew the brake hose banjo bolt and detach the hose from the caliper. Separate the caliper from the steering knuckle (front) or the torque plate (rear) - it's part of the brake pad replacement procedure. Note: On 2004 and later models, use new stainless-steel slippers when reinstalling the calipers. Connect the brake hose to the caliper, using new sealing washers. Tighten the banjo bolt. Bleed the brakes. This is not necessary if the banjo bolt was not loosened or removed (if the caliper was removed for access to other components, for example). Install the wheel and lower the vehicle. Tighten the lug nuts. Pump the brake pedal several times to bring the pads into contact with the disc. Test the operation of the brakes before placing the vehicle into normal service.

Install the dust boots on the pistons and seat the boots in the caliper. Then push the pistons to the bottom of the bores.
