FRONT DISC BRAKE PADS
To prevent master cylinder overflow when caliper piston is depressed, remove and discard
some brake fluid from master cylinder. Raise vehicle and support using safety stands.
Remove front wheel assemblies. Place a large "C" clamp on caliper. See Fig. 2. 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 and wire aside. Compress anti-rattle
spring clip and remove inner brake pad.
Press outer ends of outer brake pad away from caliper. Slide torque buttons out of retention
notches. Remove outer brake pad. Support caliper aside. Replace pad if lining thickness is less
than specified. See MINIMUM PAD LINING SPECIFICATIONS (FRONT) table.
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
To install, reverse removal procedure. Use "C" clamp and old pad to push caliper piston into piston
bore until piston bottoms out. Bleed air from brake system.
