CAUTION

Do not attempt to stop the pedal

travel with the valve plunger rod

alone.

the pedal (9) is fully released, and resting on its stop,

turn the pedal stop adjusting screw (14) in or out until

correct adjustment is obtained.

f. Service Brake Pedal Adjustment. The ideal

pedal free play is h inch. Too little free travel will prevent

the master cylinder piston from returning to full OFF

position and the brakes will begin to drag after several

applications. Excessive free travel will reduce the usable

stroke of the master cylinder.

Refer to figure 3-28 and adjust as follows:

(1) Remove the floor plates.

(2) Slowly depress the brake pedal and check

for 1/2 inch free travel. Also observe push rod action.

(3) To obtain the proper free travel, loosen the

locknut on the clevis and then turn the adjusting nut.
