Post Front Brakes stay on.

Hi, My 78 3/4 front brakes will stay on afater you release the pedal. I thought the calipers were seized but if you open the bleeder you can move the pistons back in quite easily. Everything moves easily (caliper slides on brackets). You should be able to push the pistons back in without opening the bleeders right? A guy at work said that maybe the hoses were collapsing internally but I dont know. When you apply the brakes the right front caliper will get stuck on hard enough that you cannot turn the wheel by hand. Sound like its the hoses? Or can the master get clogged so that the fluid wont return? I need help here guys. thanks. CoryM

The hose can collaps,cracking the bleeder valve on that caliper would release the pressure and help you isolate the problem. If caliper releases you know problem isn't caliper,but probably hose. After closing bleeder try to lock up caliper agin by pumping brakes. After it locks up then crack fitting where steel line connects to that calipers hose.If that doesen't release pressure on caliper you have isolated problem to the hose.Improper clearence at m/c push rod could cause problem but should effect more than one brake. Backing off m/c mounting stud nuts would isolate that problem.The m/c moving away from push rod would release pressure. Good luck W.C.

Guarantee it is the rubber hose going to the caliper. You might as well replace both sides while you got her down.

Thanks Guys..... when I get told something by 3 different people I am smart enough to not argue I replaced the hoses and it fixed it. Thanks again. CoryM
