How to tackle common mistakes in the Air Brakes Practice test?
Some common mistakes in air brakes practice test and how we can avoid them are:
Check the air brake system
Not checking the air brake system parts for leaks, cracks, or damage during the pre-trip inspection. This can lead to brake failure or reduced braking efficiency. To avoid this mistake, we should follow the steps for inspecting the air brake system as outlined in the CDL manual and use a soap solution to detect any air leaks.
Release the parking brake
Not releasing the parking brake before testing the air pressure. This can result in inaccurate readings of the air pressure gauge and the low air pressure warning signal. To avoid this mistake, we should make sure to release the parking brake and apply the service brake before testing the air pressure.
Locking the wheels
Locking the wheels for longer than an instant during hard braking. This can cause skidding, loss of control, or increased stopping distance. To avoid this mistake, we should use controlled braking or stab braking techniques to modulate the brake pressure and prevent wheel lockup.
Using appropriate pressure
Not using the appropriate pressure for the air brake system. This can affect the braking performance and safety of the vehicle. To avoid this mistake, we should maintain the air pressure between 100 and 125 psi for normal operation and never let it drop below 60 psi for single vehicles or 80 psi for combination vehicles.
