Vehicle InspectionQuestion 23 of 120
You are checking slack adjusters on an S-cam brake by pulling the pushrod by hand with the brakes released. What indicates the brakes are out of adjustment?
a.The pushrod moves more than about one inch where it leaves the chamber
b.The pushrod does not move at all
c.The slack adjuster is warm to the touch
d.The brake chamber is mounted upside down relative to the axle
Explanation
More than roughly one inch of hand movement at the point the rod leaves the chamber signals brakes that need adjusting and will not develop full force. No movement is normal for a properly adjusted brake, warmth is expected after driving, and chamber orientation varies by design.
