Home › CDL Practice Tests › Air Brakes Questions › Question 27
During inspection, a pushrod stroke is found to be beyond the allowable limit for its chamber size. What does this mean?
- A.The brakes are adjusted perfectly for heavy loads
- B.The brakes are out of adjustment and braking force at that wheel is reduced until it is corrected
- C.Only the gauge needs to be replaced
- D.The vehicle can be driven indefinitely with no change
Correct answer
B. The brakes are out of adjustment and braking force at that wheel is reduced until it is corrected
Why
Excess stroke means the chamber is using its travel just taking up slack, leaving less force to apply the brake. Out-of-adjustment brakes are a leading cause of poor stopping and failed roadside inspections.
