Went to bleed my brakes today, one of the rear ones has given up the ghost and won't open up when loosened. Everywhere I look it simply says bleeder not in stock (ie Rock Auto, Advance, Autozone etc and Jaguar doesn't even list em as a part. Looking for the thread size and length so I don't have to take the blasted thing out and try to measure it while having fluid get all over the place. Anybody happen to know what size they are? Mine has the XFR calipers. Thanks!
