Adjustment is for cars without power brakes. Pedal height should be 7 15/16". ±1/8" from the top of the pedal pad to floor pan. To adjust, loosen lock nut and adjust stop screw located on underside of brake pedal support. Make pedal freeplay adjustment as follows: Push master cylinder push rod until it contacts hydraulic piston, then turn push rod so clevis pin can freely be installed into brake pedal. Tighten push rod one full turn for proper freeplay. Tighten lock nut and connect push rod to brake pedal.
