BRAKE

3. BRAKE SYSTEM

3-1. Description and Operation of Brake Circuit

Description

Made up of parking brake switch  pedal (1), foot brake switch (2), diode unit (3), F-R lever switch (4), pump 
neutral relay (A3) (5), pump neutral holding relay (A4) (6), parking brake solenoid valve (7) and brake (8).The 
foot brake switch is ON with the brake pedal released and OFF if pushed down on.

Operation

 To release parking brake:

When parking brake switch (1) is set to the OFF position, the contacts of parking brake switch (1) close the 
circuit to parking brake solenoid valve (7) and breaks the circuit to the brake indicator lamp.

This leads the pressurized fluid through parking brake solenoid valve (7) to pistons (a) of brake (8) to compress 

springs (b). Brake is freed.

 

To apply parking brake (Brake pedal not depressed):

If parking brake switch (6) is put in the ON position, the contacts of parking brake switch (6) break the circuit to 
parking brake solenoid valve (7) and close the brake indicator lamp circuit.

This stops feeding the fluid from parking brake solenoid valve (7) to brake (8). Springs (b) move pistons (a) 

toward the brake discs and plates so that they make a close contact with each other. The brake is applied.The 
indicator lamp comes on simultaneously.

 

When brake pedal is pushed down on:

If brake pedal is depressed, foot brake switch (2) is switched off to break the circuit to parking brake switch (1).
This applies the brake even if parking brake switch is in the OFF position.
