got the stifflers lines installed yesterday, Right Rear brake caliper still dragging....ugh...
at least the stainless lines look cool
today I pulled the caliper off, used a piece of wood to keep the piston from coming all the way out, then worked the caliper piston in & out about 10 times....still no change. I used the pedal to push it out, and a c-clamp to push it back in....it moved easily.
I noticed that the piston is falling apart under the metal cap, so I ordered a new piston and new caliper guide pins/bolts and new boots that'll be here on Tuesday.
THE ONLY thing left that could possibly be bad is the guide pins are slightly bent, causing just enough misalignment that the caliper drags.
