STRUCTURE AND FUNCTION
60-18 EX20 Series
BRAKE
Wheel brake
Brake valve
When the brake pedal is operated, the hydraulic oil in the power steering hydraulic circuit is adjusted to a pressure that
matches the amount that the pedal is depressed, and this actuates the wheel cylinder. If the engine stalls and the flow of
oil from the hydraulic pump stops, the pressure stored in the accumulator makes it possible to carry out braking operations
several times.
