MartinL Posted June 28, 2010 Report Share Posted June 28, 2010 I think my master is finally dead, after Sundays run to the Gaydon show I was feeling less than happy with my soft brakes and thought I would have "one last try" at bleeding................. Started by depressurising system, about 40 pedal pushes, remove top to find the rear resevoir looking like milk it was so full of minute air bubbles!! after a few minutes bubbles dispersed and fluid looking normal although level was slightly down...............time to experiment as something very odd going on, push pedal down slowly and a million small bubbles emerge from bottom of rear resevoir, more on release and continue for several pushes, allow fluid to clear and try again, this time no bubbles, at this point I am thinking I had found and released some trapped air, great..........replace top and turn on power to run pump, try pedal..........feeling much better, best have a run down road to try............. Oh shit, just the same soft pedal. Started whole procedure again, more bubbles in fluid, then noticed the puddle of fluid under the master!! My conclusion is the master seals on the rear section have failed allowing air into cylinder and allowing fluid to weep out. Anyone got a spare master cylinder??? Are new masters still available ??? Do I rip it all out and fit an alternative system?? Any bright ideas ???? My original complaint was the lack of assistance, but it looks like I have only had any real effort from the front brakes for some time although the rears were good enough to pass an MOT ???
