Home › CDL Practice Tests › Air Brakes Questions › Question 136
What should you look for when inspecting brake chambers and their mounting?
- A.Chambers should move freely on loose mounting bolts
- B.A chamber with a bent pushrod is acceptable if the brakes still stop
- C.Chambers should be secure, not cracked or dented, and the air hoses should be connected and undamaged
- D.Oil dripping from the chamber drain is a normal sign
Correct answer
C. Chambers should be secure, not cracked or dented, and the air hoses should be connected and undamaged
Why
The chamber converts air pressure into the force that applies the brake, so cracks, dents, and loose mountings threaten that force. Damaged chambers or hoses can leak air or fail to move the slack adjuster through its full stroke.
