Home › CDL Practice Tests › Combination Vehicles Questions › Question 172
You find a trailer brake chamber pushrod with clearly excessive travel on one wheel. What does this suggest and what should happen?
- A.Excess travel makes that brake stronger than the others
- B.That brake is out of adjustment or worn and will do less braking; it must be adjusted or repaired before the trailer is used
- C.It is normal for one brake on each trailer to have long travel
- D.It only affects the parking brake, so the trailer can go
Correct answer
B. That brake is out of adjustment or worn and will do less braking; it must be adjusted or repaired before the trailer is used
Why
Pushrod travel beyond limits means the brake cannot develop full force, unbalancing braking across the combination. Uneven trailer braking is a skid and jackknife contributor, so the defect is corrected before dispatch.
