Cerbera Brake servo and master cylinder replace

[Gareth Pomford]

Has any body done this to there car ? The problem that i have got is that sometimes when i apply light breaking pessure the pedal slowly sinks to the floor , however once they are servoed back up applying firm braking pressure they work fine .The TVR garage want to replace both Servo and master cylinder, however having spoken to a few people they seem to think that the fault is the master cylinder seals.It looks like a pain to repair because the pedal cage has to come out Hence the £300.00 labour quote (Wish i could earn £300.00 a day)Anyhow , Has any body got any part number's for the above or know what car they are off.
