cause this problem?
A. leaking primary piston cup in master cylinder
B. leaking power brake booster
C. leaking residual check valve in master cylinder

pressure - -B
-5. A technician has just overhauled the front brakes on a
vehicle with front disc and rear drum brakes. However, when
he attaches a pressure bleeder (pressurized to about 25
psi) to the master cylinder, he cannot get any fluid to come

,B. bad pressure differential valve
C. proportioning valve release button not activated
D. metering valve release button not activated - -D
-6. On a vehicle with single piston floating caliper front disc
brakes, the brake pads on the left side of the vehicle are
almost completely worn while the right side is almost new.
