Duh......No wonder she had the stopping distance of a Mack truck Figured the front pads were simply tired & spent the season w/ the proportioning higher on the rear brakes to offset the weak fronts. As part of the Winter mods, was in the process of swapping the front pads for a good set of Hawk HP Plus pads & found what I should have expected; rebuild time.
Something about hot brake fluid, steel pistons mounted inside of an aluminum housing, sealed w/ rubber (viton or whatever). There just seems to be a reaction (either temp &/or chemical) among the four that causes the rubber & aluminum to produce a paste that gunks up on the steel pistons. Once this happened, the pistons got caught up. This resulted in one free, but gunked & one piston just about frozen w/ very little movement.
Am pretty good about changing fluid after track days. Maybe they were just due, but the piston area sure did look messy. Anyway, am happy to have found the issue.
