how to replace rear brake pads
Hello .. thanks for the donation .. much appreciated
Hope this helps .. let me know
REAR BRAKE PADS
CAUTION:When using a large C-clamp to compress a caliper piston into a caliper bore of a caliper equipped with an integral park brake mechanism, do not exceed more than 0.039 in. (1 mm) of piston travel. Exceeding this amount of piston travel will cause damage to the internal adjusting mechanism and/or the integral park brake mechanism.
Removal (Standard Duty)
Inspect the fluid level in the brake master cylinder reservoir. If the brake fluid level is midway between the maximum-full point and the minimum allowable level, no brake fluid needs to be removed from the reservoir before proceeding. If the brake fluid level is higher than midway between the maximum-full point and the minimum allowable level, remove brake fluid to the midway point before proceeding.
Raise the vehicle and suitably support. Remove the tire and wheel assembly.
Using a large C clamp, compress the brake caliper piston into the brake caliper bore to gain enough clearance to allow the brake caliper to pivot off the brake caliper bracket. Compress the piston until resistance is felt, but no more than 0.039 in. (1 mm) of piston travel.
Remove the park brake cable guide bolt from the lower control arm. Remove the bottom brake caliper pin bolt.
NOTE:Support the brake caliper with heavy mechanic's wire, or equivalent, whenever it is separated from it's mount and the hydraulic flexible brake hose is still connected. Failure to support the caliper in this manner will cause the flexible brake hose to bear the weight of the caliper, which may cause damage to the brake hose and in turn may cause a brake fluid leak.
Pivot the brake caliper body upward and secure out of the way with heavy mechanic's wire. Do Not disconnect the hydraulic brake flexible hose from the caliper. Remove the inboard and outboard brake pads from the brake caliper bracket. Remove and inspect the brake pad retainers.
Inspect the brake caliper bolt suspension boots for cuts, tears, or deterioration. If damaged, replace the brake caliper pin boots. Inspect the brake caliper pin bolts for damage or corrosion. Replace if damaged or corroded. Do not attempt to clean away corrosion. Corrosion is typically caused by damaged pin boots. See DISC BRAKE MOUNTING HARDWARE INSPECTION in DISC BRAKE SYSTEM under TROUBLE SHOOTING.
Inspect the brake caliper piston boot for deterioration, repair or replace the brake caliper if damaged. See REAR BRAKE CALIPER under ADJUSTMENTS & INSPECTIONS.
Retract the brake caliper piston into the brake caliper bore. Use a spanner type wrench to turn the piston clockwise until it bottoms in the brake caliper bore and align the piston. Align the cutouts in the brake caliper piston to the alignment pins on the brake pads. Apply a thin coat of high temperature silicone lube to the rear brake caliper pin bolts.
Install the brake pad retainers into the brake caliper bracket. Install the inboard and outboard brake pads into the brake caliper bracket. Pivot the brake caliper down over the brake pads and into the brake caliper bracket.
Insert the lower brake caliper pin bolt. Tighten the brake caliper pin bolt to specification. See TORQUE SPECIFICATIONS .
Install the park brake cable guide bolt to the lower control arm. Tighten the park brake cable guide bolt to specification. See TORQUE SPECIFICATIONS .
Install the tire and wheel assembly. Lower the vehicle.
With the engine OFF, gradually apply the brake pedal to approximately 2/3 of its travel distance. Slowly release the brake pedal. Wait 15 seconds, then repeat until a firm brake pedal apply is obtained; this will properly seat the brake caliper pistons and brake pads.
Fill the brake master cylinder reservoir to the proper level. See MASTER CYLINDER RESERVOIR FILLING under BLEEDING, FILLING & FLUSHING BRAKE SYSTEM. Burnish the pads and rotors.
