A. Glazed Drums
B. Wrong linings installed
C. Low air pressure in the service tanks
D. Governor cut-out pressure too high - ANSWER✔✔Answer A is incorrect.
Glazed drum linings are hard and do not wear. They also do not stop the truck.
Answer B is correct. The wrong lining for the application may be the problem.
Answer C is incorrect. Low air pressure in the tanks would not cause brake wear. It
may cause a low amount of reserve air in case of multiple brake applications.
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.
Which of the following could case one brake on a truck to wear faster than the
others?
A. Mismatched service brake chambers
B. Mismatched parking brake chambers
C. Low air pressure in the service tanks
D. Governor cut-out pressure too low - ANSWER✔✔Answer A is correct.
Mismatched brake service chambers would apply unequal brake application
pressure from side to side, which would cause one brake to wear faster.
Answer B is incorrect. Mismatched parking brake chambers would not cause brake
wear. It would possibly allow the brake to roll when parked, because one side
could have insufficient parking brake application.
Answer C is incorrect. Low air pressure in the tanks would not cause brake wear. It
may cause a 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.
