It was easy to find the bleeder thread size for the Mini - M10x1.0 - however, there are two lengths of bleeder valves available in that thread size. Anyone know which one to get for the stock R53 brakes? the short one is 1.23" (31.35mm) the longer one is 1.35" (34.44mm) Speed Bleeder Sizes I don't really want to take out a valve just to measure it, but I guess that's the next best thing to do. I've done the google thing several times with all types of keywords to get to an answer, but I can't find a part number and the Russell web site is useless to ID it by car. I know I can just order whatever some not to be named shop sells, but then I am a cheap bastard and don't want to spend $75 for four valves when I can get them for less than $50 once I know the Russell part number.
