i have a 1999 chevy cavalier and i just put new brake lines on all around. when i got the car, the back brake lines where rotted right through. i have changed everything after the master cylinder,(drums, callipers, wheel cylinders, pads..) now i cant bleed the back brakes, but i can bleed the front. i have no pressure coming into the back brake lines what so ever. PLZ HELP!!!|||Your proportionong valve is keeping fluid from going to the back.
When a brake line breaks, the prop valve moves (internally) to keep all the fluid from leaking out (from the master cylinder) The valve needs to be re-set to let fluid go to all the wheels|||Did you crimp one of the lines or do you have a leak? I know how you flare the lines together is pretty important also. you need a special tool . good luck.|||Double you de forty
