Results

#1. During a pre-hill inspection of a vehicle equipped with hydraulic brakes, you should do which of the following?

Make sure that there is adequate pedal reserve.

Make sure there are no hydraulic fluid leaks.

Make sure that the brake drums are not overheated.

Do all of the above.

Whether your vehicle has air brakes or hydraulic brakes, it is important to make sure that the brake drums haven’t overheated. To test hydraulic brakes for leaks, first pump the brakes three times. Next, apply firm pressure to the brake pedal for five seconds. The pedal should not move. If it moves, the brakes may have a leak or some other problem.
