Disc Calipers & Pads: Installation
- Using silicone lubricant, coat and install new sleeves and rubber bushings in caliper ears. Attach shoe support spring to inboard shoe. Ensure that shoe is installed in caliper with wear sensor to rear of vehicle. Shoe should be flush against piston.
- Position outboard shoe in caliper. Engage tab at bottom of shoe with caliper cutout and shoe ears with caliper ears at top of shoe. Place caliper over rotor, aligning caliper ears with mounting holes.
- Start bolts or pins through inboard caliper ears and mounting bracket. Make sure bolts or pins pass under retaining ears of inboard shoes.
- Push bolts or pins through caliper to engage hole in outboard shoe and ears of caliper. Thread bolts into mounting bracket and tighten to 38 ft. lbs. (51 N.m). Measure clearance between caliper housing and bracket stops. If necessary, file ends of bracket stops to provide proper clearance. See Fig 1.

- Use pliers to clinch upper ears of outboard shoe against caliper. See Fig 2. Make sure ears are flat against caliper with no clearance.
