Title: 22.2mm master cylinder
Post by: BrettG40 on April 14, 2011, 08:22:05 pm

Alright guys, fitted one of these off a mk2 golf 16v, bled all the brakes perfect no air whatsoever, but theyre binding theyre constantly on, any ideas?

Cheers.

Sounds like there's a blockage stopping the fluid bleeding back. Quite possible if it's a used master cylinder.

Ive fitted a brand new unit the one side only a few days ago as the bleed nipple snapped off in the old one so could that have anything to do with it?

maybe the other side - if its crusty in the drum, it'll stick open

if all four brakes are constantly on all the time then I'd probably say it's a duff master cylinder although I've never seen anything like that happen.  Usually a duff master cylinder means you have no brakes.
