Which of these is a correct check of the parking (emergency) brake during an inspection?
- A.It only needs checking on vehicles with hydraulic brakes
- B.It works if the handle feels loose
- C.It should release automatically above 5 mph
- D.Set it, then try to move gently to confirm it holds the vehicle
Correct answer
D. Set it, then try to move gently to confirm it holds the vehicle
Why
A parking brake that cannot hold the vehicle is useless in an emergency or on a grade, so you verify it actually holds. On air brake vehicles this is the spring brake system, which also applies automatically if air pressure is lost.
