Section XVI. BRAKES

3-60. General

a. Brakes on the fork lift consist of two systems:

c. The service brakes are hydraulically actuated

a hand operated parking brake on the propeller shaft

through a pedal and master cylinder. Depressing the

pedal operates the master cylinder sending

and service brakes on the two front wheels.

b. The parking brake is a dual-shoe mechanical

hydraulic pressure to the wheel cylinders. The wheel

cylinders are the double end type and hydraulic

operated type. Actuation of the brake is accomplished

pressure extends the ends of the cylinder, pivoting

through a brake lever mounted on the left of the in-

the brake shoes against the brake drum inside the

strument panel. Pulling the brake lever to the rear

wheel. The pressure in the master cylinder also closes

tightens the cable and moves the cam lever at the

brake up. Movement of the lever expands the brake

the stop light switch and operates the stop light.

When the pedal is released, springs return and the

shoes against the drum. This pressure keeps the shaft

from rotating, locking the front wheels and holding

pedal and brake shoes to the released position. The

brakes are self-adjusting.
