Hey guys im having a problem with my front right calaper sticking after you drive around for about 15 min. i have changed the brake lines, blead the brakes, and changed the hard ware and the problem still prosists. if anyone can help please post. Btw its on a 91 s5 with 4piston claipers with solid suspension

Brake caliber is wasted, pick up a rebuilt unit and bleed out the brakes. (Corrosion on pistin caliber or both) Might just as well replace both front as the other won't be far behind. Local auto parts store should be able to get them.

That was my guess as well, a bad caliper. There are rebuild kits available (I'm not sure where, I've only read about it), but swapping a caliper is as easy as changing brake pads.

thanks there on there way
