For front disc pad removal and installation, see FRONT BRAKE CALIPER procedures, but do not disconnect brake hose from caliper (wire aside). Replace all pads on an axle if wear indicator on any pad contacts rotor or if pad is worn to within 1/32" (.8 mm) of pad backing.

Removal (Floating Caliper)
Remove 2/3 of brake fluid from master cylinder. Raise and support vehicle. Remove wheel. Using "C" clamp or large pliers, compress caliper piston until it bottoms in its bore.
Disconnect brake hose from caliper. Remove caliper guide pins. See Fig. 25. Remove caliper. Remove pads from caliper. Note retainer spring on inner pad (some models) and remove if replacing pads.
Installation
Remove caliper sleeves from caliper. See Fig. 25. Apply silicone grease to outer diameter of caliper sleeves and inner diameter of bushings. Insert caliper sleeves into bushings.
Install retainer spring on inner pad (if removed). Install pads in caliper. Install caliper. Install guide pins and tighten to specification. See TORQUE SPECIFICATIONS table.
Connect brake hose to caliper and tighten hose bolt to 32 ft. Lbs. (43 N.M). Bleed brake system. See MANUAL BLEEDING or PRESSURE BLEEDING under BLEEDING BRAKE SYSTEM.
If outer pads are equipped with locking ears, bend ears toward caliper until ears touch caliper. This prevents movement of outer pad in caliper. See Fig. 10. Install wheel.
