1996 drum brakes
A 1996 chevy rear end in a street rod with drum brakes. Have been driving it for 7 years no problem. Now when you drive it the brakes adjust their selfs out and get hot and gradualy slow you down. You have to take the drums off and turn the stars back. If you leave it sit and cool down you can drive it for another 20 miles again with out doing anything. What is causing this. THANKS IN ADVANCE FOR YOUR RESPONSE.

  • Yep. This happens way more than we think. That inner hose ripples into a clog.

  • It is fixed, Thanks again for your comments. After trying different things I was told to replace the 10 inch rubber hose from the top of the rear end to the main line coming back from the front. That fixed it. The hose must have been colapsing and would not let the fluid return.

  • The problem has been like what Willie said is the master cylinder is not coming back into the neutral position . It is leaving just a slight pressure on the wheel cylinder which engages the shoes and as it get hot ,as it expands the shoes ! Do you have power brakes? As here is another issue that has been a problem . As there is a adjuster in between the master and the booster that sometimes was not tight from the factory and it moves out doing the same problem ! Putting pressure on the master cylinder engaging it . Also Check to make sure the pedal is coming all the way back as with age it gets dirt and stuff under the dash in the swivel mechanisms and gets gummy not allowing the pedal to come back leaving a little pressure on the master cylinder doing the same thing, Check to see if your return brake return spring broke ! May have to put a return spring on it if it's broke or missing ! Good luck !

  • I know someone who had the same issue. The brake master cylinder was not releasing all the way. Next time it happens open the bleeder on the rear brakes and see if that corrects the issue.
