Post Bleeding Power Disc Brakes

Hello,My question is I'm having a problem getting the rear brake calipers to close, while the front seem to be o.k.It seems like theres not enough pressure going to the back? Is there something i'm not doing correctly while bleeding the power disc brakes? thanks......Jeff

I had this same problem with my car and it turned out that it was old flex hoses that had partially colapsed on the inside. I discovered it by disconecting the flex hose from the front, had someone depress the brake pedal and noted the amount of fluid I was getting. Did the same thing with the rear and I was getting about 80% less fluid. Replaced the flex hoses on the rear and that fixed the problem. You might try that same test. This was on a Corvette where there was a flex hose for each wheel. On some cars you may have only one flex hose near the diferential that supplies the brake lines on both sides.

Let us know what you find out.

i agree with jim. also check which brake is the farthest from the mc. a friend had a similar problem on a started project he bought. for some reason the brake line was run to the farthest wheel first and then to the drivers side. remember to bleed the wheel farthest from the mc first,gets the majority of the air out. hope you get it fixed soon. good luck.

JJ: You might check proportional valve that regulates the flow of fluid between back and front brakes. Most pressure is applied to front brakes first. A good source is Master Power Brakes www.mpbrakes.com . They offer a number of adjustable valves and good advice GOOD LUCK Dave E Shank
