Reply to "rear brake problem?"

First, I'd suggest rebuilding the rear calipers. This is quite simple and the seals etc are relatively cheap & available from all the usual Pantera vendors including the host of this Page. These are one-piston sliding calipers, so once removed & rebuilt, put a dab of grease on each of the two sliding areas on each caliper body so they can move in their bracket. And to release the tricky self-adjuster inside, rotate the piston to the 45 degree position and the whole thing slips apart, from either end.
