Brake hell

Hi all got a question. After about an hour of drivin (or when the beast is warmed up) the rear brakes start to stick when applied. Ive swapped out brake lines, power booster, bled the brakes a couple times, and inspected the whole system. So at this piont before I sink a bunch of money into it for a master cylinder or rebuilding the calipers Id like some advice.
Also the brakes I have on it have two bleeders in the back-per caliper. Am I correct in thinking that they should have one each for a 75?
On a last note just got back from Albuquerque Mon night. Was looking foward to takin the top off here in FL but looks like it will rain all week, figures dont it.
Thanx

I'm far from an expert on brakes, but it sounds like you may have some gunk built up in one or both of the calipers. I did an overhaul of all the calipers on 'The Toy' a couple of summers ago and it wasn't that tough a job. Bought a honing tool, caliper rebuild kits, a couple of cans of brake cleaner, a pair of haz. mat. gloves and a gallon of brake fluid. I took my time as it was the first time I'd ever attempted to overhaul calipers. Haven't had a problem with any of them since.

Don't have an answer for you on when the dual bleeders on the rear calipers were used or not used. Zen-Master Ken will probably know. He be 'da Answer Man'...!!!

Norsky covered it pretty well, I would also try the rebuild idea unless they are still the old style "unlined" (no stainless insert in the bores) calipers. This is assuming you have already changed the flexible brake hoses. I would recommend getting the o-ring style calipers if yours are still the old type. There are 2 bleeders on the rear brakes, but only one on the fronts.

Jim you did well. Exactly right.
Steve answered the rest.

Sweet thanx all. Can anyone recommend a good rebuild kit w/the "o"-rings?

I agree hole hartedly with the O-ring calipers. I fought mine for years had run out and nobody ever expained it to me. Like 5 brake shops. Called Vette Brakes the guys there expained everything from A-Z. I got there O-ring rebuild kit. After one saturday of work and I haven't touched them for two years. I am very pleased. If I can help let me know.

Well the nightmare continues. Swapped out (so far) the power booster, brake lines, rear calipers, and bled about a hundred times. They are still sticking! I have to say not as bad as they were though. Any ideas
Glenn

how about proportioning valve ???

Well swapped out the proportioning valve and still same same. I have no idea what it could be! Any hope that the rotors have been ground to much and maybe the pucks are sticking out to far?

Suggest you mike the rotors. Minimum thickness is 1.230". The minimum thickness should also be cast into the rotor. Be real careful of the Chinese replacement rotors that are available at a low cost, they often warp first time they get hot. Got Rayloc replacements for mine through NAPA.
