Question

Hey guys, this is about my 78 Chevy pickup. I am posting it here because you guys are the best!! The problem I am having is that after I stop at a light or whatever my brakes are not releasing all of the way. I don't think it is all of them. Yesterday I took off the right rear drum. I adjusted it all the way down and still had trouble getting it off. I took apart the wheel cylinder and put it all back together, and still no luck. I think the right front is sticking too, but it is hard to tell, maybe they all are sticking. I put a new master cylinder in a couple of months ago so i don't think that is the problem. I am gonna flush out the old brake fluid and see what happens. Could it be the booster maybe?
Any ideas would help, thanks.

If the locking it's just one wheel,check the brake hose. I have seen then all cloged, the fluid runs to the cylinder or caliper at high pressure but doesn't return cause of the cloged hose. just a hint, good luck.

If you loosen the bleeder screw does that brake release?How about cracking the master cyl. line at the master does it release?Try the front line and check the rear brakes, then the rear line,and check the front brakes.

its your rubber hoses, they are collapsing in on themselves internally, thuse causing residual pressure, there only 14 bux, get new ones. even if they look clean, they could be bad. you cant tell untill you replace them... but I gauruntee if your cylinders are good and the shoes/pads are fine, the hose is the culprite.. just be carefull on the removal of teh brake line, I had snapped mine and had to re-flare it.

Thanks for the replys guys. I will change the rubber hoses and flush the fluid this weekend. What is the best way to flush the fluid. Do I need one of those little vacume pumps or can I let gravity do the work? Thanks again!

Make sure you have the right Mast Cyl...Also,if the brake pushrod is out of adjustment, it could be keeping the brakes under pressure which will cause the brakes to heat-up as you drive around

Drive the car for a while and put you hand on all four wheels, the heat will indicate the problem wheel.
I had a caddy convert (boss hog car), a brake line was collapsed and the rotor would get cherry red
Gravity and pumping will do the trick of fluid exchange

What is the brake pushrod? Does it push the brake shoes? Thanks again

The brake pushrod is the rod that extends from the brake pedal to the master cyl. I am not sure about your application, but on some applications it is adjustable. It is is adjusted too long, then it is the same as riding around with your foot on the brake.
