sub205 5 Posted November 6, 2009 Hello, my right rear brake is not working, only the parkingbrake works as expected. i dont think its air in there because i use a 2way master cylinder from a 306 xsi with splitters and my front brakes are perfectly symmetrical. could only be the pressure lowering valve or ... ? tomorrow i'll check if fluid comes out. but i think thats not a 100% secure sign of everything working?

Anthony 1,002 Posted November 6, 2009 If it's a non-ABS 1.9 GTi, then it'll almost certainly be a failed rear compensator valve (there is one per side) Share this post Link to post Share on other sites
