7 . Front wheel braking works:
Under most conditions.
Front wheel braking is effective under all road conditions. It is unlikely that you will experience a front wheel skid, even on ice.
8 . How is water and compressor oil removed from the bottom of an air storage tank?
A sponge is used to soak up the water and oil.
Water and compressor oil are removed from air storage tanks through a drain valve. The water and oil can damage the brakes if left to accumulate in the system. Manually operated tanks must be drained every day to remove this build-up.
9 . In a dual air brake system, if one air system is very low on pressure:
In a dual air brake system, either the front or rear brakes will not be fully operable if one of the air systems gets too low on pressure. If the air pressure in either tank gets too low while you are driving, you should exit the road and park as soon as possible.
10 . What is brake lag?
How faded the brakes are
Because air takes time to flow through the air lines to the brakes, air brakes cannot begin working instantly. There is often a brake lag of at least one-half of a second between the moment the brake pedal is pressed and the moment the brakes begin to work. On vehicles with hydraulic brakes, the brakes work instantly when the pedal is pressed.
11 . Brake fade is a result of:
If brakes are overused, they can become too hot. This overheating causes them to fade, making them less effective at slowing the vehicle.
12 . The most common type of foundation brake used is the:
P-cam disc brake.
