1 . When leaving your vehicle unattended:

Always apply the parking brake when leaving your vehicle unattended.

2 . If the safety relief valve in the air brake system releases air:

An air brake system has a safety relief valve, which releases air from the tanks if the pressure gets too high. If the valve must operate, something in the system is wrong and should be addressed by a mechanic.

3 . Brakes can get out of adjustment quickly, especially:

Brakes are particularly prone to getting out of adjustment if they are hot. Be sure to routinely check the adjustment of your brakes. For a vehicle to be safely controlled, all brakes must be properly functioning and adjusted.

4 . A safety valve is set to open at ____ pounds per square inch (psi).

The safety valve protects air tanks and the rest of an air brake system from accumulating too much air pressure. The safety valve is usually set to open at 150 psi.

5 . What can happen if the air pressure gets too low in an air brake system?

Pressing and releasing the brake pedal unnecessarily can let air out of the braking system faster than the compressor can replace it. Air brakes may cease to work effectively if the pressure becomes too low.

6 . The air storage tanks:

The air storage tanks in an air brake system store compressed air to be used for braking. They hold enough air for the brakes to still be used several times if the compressor stops working.
