one thing I learned long ago... ask questions, you'll be amazed at what other people know that you might not know,
or remember.
Ive got a guy in my shop that has zero brake fluid pressure on the pass side front brake caliper feed line
there does not appear to be anything wrong with the master cylinder as the drivers side front brake works fine
and if I bleed the brake theres zero fluid pressure reaching the pass front brake, there appears to be no line damage so the brake
modulator valve,behind the divers seat looks to be defective? or some pressure sensor or perhaps a fuse is blown?

IF YOU CAN,T SMOKE THE TIRES AT WILL,FROM A 60 MPH ROLLING START YOUR ENGINE NEEDS MORE WORK!!"!
IF YOU CAN , YOU NEED BETTER TIRES AND YOUR SUSPENSION NEEDS MORE WORK!!

After doing some extensive research, the crew at Corvette Salvage has determined that the Brake Pressure Modulator Valve (ABS Pump) within 1986 to 1991 Corvette models is prone to failure. Many components within the pump tend to break down due to the corrosive nature of the hydraulic braking fluid which causes the pump to quit functioning properly.
