of multiple brake applications.
D. Governor cut-out pressure
too high Answer D is incorrect. High governor cut=out pressure
may cause the safety valve to open, but would not
cause the brakes to wear too fast.
Answer A is correct. Mismatched brake service
Which of the following chambers would apply unequal brake application
could case one brake on a pressure from side to side, which would cause one
truck to wear faster than brake to wear faster. Answer B is incorrect.
the others? Mismatched parking brake chambers would not cause
A. Mismatched service brake
chambers brake wear. It would possibly allow the brake to roll
B. Mismatched parking brake when parked, because one side could have insufficient
chambers parking brake application.
C. Low air pressure in the

would not cause brake wear. It may cause a low
D. Governor cut-out pressure
too low amount of reserve air in case of multiple brake
applications Answer D is incorrect. Low governor cut-
out pressure may cause an inadequate
amount of air in reserve but would not cause the brake to wear
too fast.
