Master cylinder dimensions

[vinny]

205 ones are quite short mate mite fit, on my mates gti think its 4 port definatly more than 2 and 20 mm piston but if ther are two many ports u can blank some off aslong as you use one front port and one rear port. two port ones usually have a couple of t pieces in the system to distribute fliud to all 4 brakes.some are 3 port indivual lines to each front and a t on the rears.
