TM 10-3930-669-10 1-17.  BRAKE SYSTEM. The brake pedal (1) stops forward and reverse movement.  Light brake application activates the inching valve solenoid on the transmission (2), which slowly disengages the transmission.  The full brake application pushes the brake linkage into the brake master cylinder (3), which drives fluid into the drive axle (4).  The brake fluid inside the drive axle moves pistons against plates that contact the brake discs, and slow down the forklift.  The parking brake (5) manually closes the brake caliper (6) on the parking brake rotor (7). 1-12
