The brakes on a vehicle work OK for a while, then the vehicle slows because the brakes self- applied. Technician A says that an overfilled master cylinder could be the cause. Technician B says that a blocked vent port (compensating port) could be the cause. Which technician is correct?

A. Technician A only

B. Technician B only

C. Both technician A and B

D/ Neither technician A nor B

C. Both technician A and B

Explanation:

If the master cylinder is overfilled it will not allow enough room for the brake fluid to expand due to heat expansion. This blocks the vent port.  If a vent port is not open, brake fluid pressure will increase as brakes heat up.  This will cause the brakes to self apply, cause more heat in the brake fluid and the vehicle will slow down.

There, we can conclude that Both technician A and B are correct.

C. Both technician A and B

Explanation:

The event that made both cylinders to be over filled especially the master cylinder and the blocking of the vent port, this will cause the vehicle brake to apply itself after just a little motion of the vehicle.

Therefore both technicians are correct from the information given above.

Hence, we can boldly say the correct answer is C. ie Both technician A and B
