Home › CDL Practice Tests › Air Brakes Questions › Question 148
Why must a cracked or badly bent brake component, such as a chamber bracket or torque arm, not be ignored?
- A.Structural brake parts keep the chamber and shoes aligned, and failure can disable that brake or make it apply unevenly
- B.Bent parts only change the appearance of the axle
- C.Alignment of brake parts does not affect stopping
- D.A cracked bracket will straighten itself under air pressure
Correct answer
A. Structural brake parts keep the chamber and shoes aligned, and failure can disable that brake or make it apply unevenly
Why
Braking force is only useful if it is delivered in the right direction through sound hardware. Cracked supports can flex or break, changing pushrod travel and leaving that wheel with little or unpredictable braking.
