Adjusting older Ford rear calipers that use pistons with two holes or a nut, in the face of the
These calipers require special procedures during caliper removal and installation to ensure a high,
hard brake pedal. Damage to the caliper piston adjusting mechanism may also happen.
Unlike most rear calipers that employ the hydraulic brake and the mechanical park brake with
the same piston, these caliper pistons must rotate to work. THEY DO NOT LOCK INTO A
BUTTON ON THE INBOARD BRAKE PAD.
To remove calipers from the rotor:
- take actuator lever off the caliper
- undo parking brake end retainer cap 1/2 turn only ( Figure 1 )
- push piston back into the caliper with C-clamp or pry bar ( do not rotate piston )
To install caliper and brake pads:
- with piston bottomed in caliper, install caliper and pads over rotor
- with pry bar, slide caliper out until the inboard pad contacts the rotor
- observe air gap to outboard pad and remove the caliper ( e.g. 1/4 inch )
- with Ford tool, socket or needle nose pliers, turn piston out of caliper. Each 360 degree
turn moves the piston out approximately 1/8 inch ( e.g. rotate almost 2 full turns )
- install caliper back onto rotor
