During the pre-trip inspection, which brake system needs to be checked to ensure it does not pull to the left or right?

Question

Accepted Answer

C: Service brake. Drive forward to about 5 mph and apply the brake pedal. The brakes should apply evenly with no pulling. If the brakes pull to one side, the brakes on the side of the pull are working correctly and it is the opposite side that should be inspected.
