DISC BRAKE CALIPERS & PADS
To prevent master cylinder overflow when caliper piston is depressed, remove and discard some brake fluid from master cylinder. Raise vehicle, and support with safety stands. Remove front wheel assembly. Place a large "C" clamp on caliper. Tighten clamp to bottom piston in cylinder bore. Remove clamp.
Remove dirt around caliper pin tabs. Tap upper caliper pin toward inboard side of vehicle until pin tabs touch spindle face. Insert screwdriver into slot provided behind pin tabs on inboard side of pin. Using pliers, compress end of pin while using screwdriver to pry until tabs slip into spindle groove.
Place a 7/16" diameter punch on end of pin, and drive caliper pin out of caliper slide groove. Repeat procedure for lower pin. Remove caliper from rotor. Remove outer brake pad. Compress anti-rattle spring clip, and remove inner brake pad. Support caliper aside.
Replace pads if lining is less than:
.06" (1.5 mm) above backing plate at any point. (F150)
.03" (.8 mm) above backing plate at any point. (F250/350 and Super Duty
CAUTION:During installation, DO NOT tap caliper pin too far into spindle groove. If this happens, tap pin in other direction until tabs snap back into place. Tabs on each end of caliper pin must be free to catch on spindle flanks.
Lubricate caliper pin and pad contact surfaces. Use "C" clamp to push caliper piston into piston bore until it bottoms out. To install, reverse removal procedure. Bleed air from brake system (if necessary).
