hi,not sure as when it came to doing the 2nd caliper i was doing it myself,.i removed the nipple and pushed the pedal,it was firm and no fluid came out of the nipple hole,i remember a few years ago my friend had a 1.6 orion ghia with abs,he had a nightmare bleeding the rear brakes because of the abs,i wondered if im having the same problem,i am waiting on a set of braided brake hoses coming so ill have to bleed it all over again!
