A driver complains the brake pedal feels normal but the truck pulls to one side during stops. Which cause fits best?
- A.One brake is applying harder than the others because of uneven adjustment, contamination, or a chamber problem on one side
- B.The fuel load is uneven in the tanks
- C.The mirrors are adjusted differently
- D.The steering wheel cover is too thick
Correct answer
A. One brake is applying harder than the others because of uneven adjustment, contamination, or a chamber problem on one side
Why
Pulling during braking means braking force is unequal from side to side, not that overall force is missing. Uneven slack adjustment, oil-soaked linings, or a weak chamber on one side are the usual suspects and all need shop attention.
