Ford F79Z-2V121-CARM Less Pads Brake Caliper Assembly

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.

Before starting work, lock the backup brake and block both front wheels. First, loosen the wheel lug nuts. Then lift and support your vehicle with jackstands, using tire jacks. Remove the wheel. Turn the brake hose banjo bolt counterclockwise and pull off the hose from the caliper. As part of replacing brake pads, move the caliper away from the steering knuckle (front) or torque plate (rear). Put the new sealing washers on the brake hose and attach it to the caliper. Tighten the banjo bolt correctly. Pad replacement requires brake bleeding when you undo or remove the banjo bolt, but you don't need to bleed if you only detached the caliper to make room for other repairs. Reinstall the wheel, then slowly bring the vehicle back down to the ground, securely tightening all lug nuts. Push and release the brake pedal several times to make sure your pads make contact with the brake disc, and then test your brakes to see if they work as they should before you put the vehicle back into regular use.

Carefully examine the piston and caliper bore for nicks, burrs, cracks, loss of plating, corrosion, or any signs of damage.
