Do you have a/the proportioning valve in your system? Pin needs to be pulled out for centering while bleeding.

I have re/re the rear brake cylinders,shoes,drums,front rotors,pads,and callipers on my 2000 gmc safari van.i have bled all the brakes. but the drivers front has no pressure or fluid.the other three brakes...


make sure you are bleeding them by doing them as an abs system,do the right rear then the left front,then the left rear then the right front,the opposite wheels are how the system brakes.

Rear brakes won't work


This is just a shot on the dark but did you use a low end brake fluid as this has been known to cause braking problems.
