Do not use the parking brake to stop the machine.
Illustration 1 g00629003
Parking Brake Control (Switch) (1) - Move parking brake switch (1) to the OFF position in order to release the parking brake. Move parking brake switch (1) to the ON position in order to engage the parking brake. The parking brake switch (1) is located on the console next to the transmission control. Use parking brake switch (1) to engage or disengage the parking brake when you park the machine.The machine is equipped with spring applied parking brakes. The spring force engages the brakes on the rear wheels. Hydraulic pressure is used to disengage the brakes. If hydraulic pressure is unavailable, the brakes will remain engaged.

If hydraulic pressure is unavailable and the machine must be towed, use brake release and secondary steering control switch (2) in order to disengage the parking brake. Refer to the Section on Towing Information in this manual or consult your Caterpillar dealer for further information on towing an inoperable machine.Front Brake Control
Illustration 3 g00629006
Front Brake Control (Switch) (3) - This switch (3) allows the operator to brake with all four wheel or with only the rear wheels. The switch (3) allows the front brake to be turned ON or OFF.
ON Position - When front brake switch (3) is positioned to the left and the service brake pedal is depressed, front and rear brakes will be applied.
OFF Position - When front brake switch (3) is to the right and the service brake pedal is depressed, only the rear brakes will be applied. Note: The front brake switch (3) should be in the ON position during normal operation.Service Brake
Illustration 4 g00629004
Do not use the front wheel brakes for retarding on long steep downgrades.Overheating may occur, causing reduced service life of the brake components.
During normal operation, depress service brake control (pedal) (4) to stop, or slow the machine. The service brake pedal (4) applies all four wheel brakes. The pedal is fully variable. The amount of braking force depends on the position of the pedal.Secondary Brake
When parking on a slope, always block the wheels securely before leaving the machine unattended.If the secondary brake system is required in order to stop the machine, do not operate the machine until a complete check has been made of the entire braking system and until all necessary repairs have been made.

Note: If service brake pedal (4) does not stop the machine, use secondary brake control (pedal) (5) to stop the machine.The secondary brake pedal (5) applies all four wheel brakes. The pedal is fully variable. The amount of braking will depend on the position of the pedal.
If the action alarm sounds, check gauge (6) for the system air pressure. If the service brake pedal (4) does not stop the machine, use secondary brake pedal (5) to stop the machine.
When the machine stops, engage the parking brake. Release secondary brake pedal (5). Allow the machine to build up air pressure. If the air pressure fails to build up, make
