Hoses

An air compressor

Air tanks

Both systems in a dual air brake systems share a single air compressor. If the air compressor is damaged, neither system will be able to operate properly.

3 . To ensure normal stopping power, drivers of vehicles equipped with a front brake limiting valve should:

Set the control to normal.

Set the control to the off position.

Set the control to the neutral position.

Some older vehicles have front brake limiting valves with "normal" and "slippery" settings. Setting a brake limiting valve to "slippery" reduces the vehicle's stopping power, so a driver should make sure the valve is in its "normal" position. Front wheel braking has proven to be effective in all driving conditions.

Turn on the lights.

Turn the vehicle off.

Push the brake pedal down.

Open the trailer doors.

In a vehicle with air brakes, never push the brake pedal down when the spring brakes are activated. The combined force of the springs and the pressure of the air brakes could damage the brakes.

Push in the yellow, diamond-shaped knob.

Pull out the yellow, diamond-shaped knob.

Pull up on the steering column.

6 . Anti-Lock Braking Systems (ABS):

Reduce normal braking capacity.

Are equipped in addition to other braking systems and do not reduce normal braking power.

Are not effective on larger vehicles.

Are illegal in some states.

ABS is equipped in addition to a vehicle's normal braking system and it neither increases nor decreases the vehicle's braking capability. ABS activates during hard applications of the brake pedal in order to prevent wheels from locking up.
