Hey guys, haven't been around much lately as my SC doesn't get driven as much as it used to, but I ran into a problem the other day that I'm tired of trying to diagnose so I figured I'd consult the experts...
I had it up on jack stands for something unrelated, and happened to notice that my front brakes are locked up. About 4-5 years ago I did the dual piston caliper swap in the front. Drove it for a couple years with no problems, then over the last few it has been driven only a few times during the summers. Still started up and moved around frequently, just not driven a bunch.
Anyways, fronts are locked up. Pulled the calipers off and took them apart to inspect, everything is fine. Replaced the front rubber brake lines to the calipers, bled the system, fronts still locked up. ABS system seems to be functioning just fine. When I crack the bleeders it doesn't relieve any pressure on the calipers which I find kind of strange. It's definitely getting pressure to the calipers just fine, but won't release the pressure. What have you guys run into? Am I looking at a faulty valve in the master cylinder somewhere that isn't letting fluid return? What else is in the system that I'm not thinking of...
