The function of a proportioning control valve (PCV) in a brake system is to

A Ensure that equal pressure is supplied to the front and rear brakes throughout every braking operation
B Reduce the brake fluid pressure when the brakes approach their lockup point
C Cause less brake fluid pressure to act on the front brakes than on the rear brakes when the fluid pressure exceeds a predetermined level
D Cause less brake fluid pressure to act on the rear brakes than on the front brakes when the fluid pressure exceeds a predetermined level

Correct Answer: Cause less brake fluid pressure to act on the rear brakes than on the front brakes when the fluid pressure exceeds a predetermined level
