1 . Foundation brakes are used:
Foundation brakes are used on each wheel of a CMV. The most common type of foundation brake is the s-cam drum brake.
2 . What tells you how much pressure is in your vehicle's air tanks?
A vehicle that is equipped with air brakes must also be equipped with a supply pressure gauge. This gauge tells the driver how much air pressure is in each of the vehicle's air tanks.
3 . When traveling down a steep downgrade:
The vehicle should be driven on the shoulder.
On a downgrade, the braking effect of the engine should be your primary method of controlling speed. Shift down to a lower gear before starting down the hill and save the brakes for additional slowing or stopping that may be required by road or traffic conditions.
4 . The air storage tanks:
Hold enough air for more than 1,000 braking cycles.
In an air brake system, the air storage tanks hold enough air for brakes to be used several times if the compressor stops working.
5 . If the safety relief valve in an air brake system is releasing air:
The safety relief valve in an air brake system releases air if necessary to prevent pressure in the system from becoming too high. If the valve starts releasing air, there is something wrong. Have a mechanic fix the problem.
6 . A wig wag is:
Vehicles with air brakes are required to be equipped with a low pressure warning device. A wig wag is a type of low air pressure warning device. This device drops a mechanical arm into the driver's view if the pressure in the tanks drops to a level between 55 and 75 psi.
