maz Posted January 27, 2011 Report Posted January 27, 2011 Im loseing brake fluid and we believe its leaking from the clutch slave cylinder, now a couple of things. If its just a seal, can just the seal be replaced or does it need a new slave cylinder? also is it an internal or external cylinder?? The brake fluid is having to be topped up every week at the mo when i get the brake fail, STOP, service manual beeping at me on the dash. Im assuming the clutch needs to be replaced at the same time, what about the dual mass flywheel?? is there a replacement part that is one unit?? and how will i know if that needs replaceing aswell?? I have searched by the way... but didnt get the answers i required. im driving around 250/300 miles a week if that makes any difference to anything. ta muchly for any help /advice given as i need this prob sorted before the clutch/brakes fail, as i believe the clutch will go first by feeling spongy? its a 52 plate 1.9tdi which has done 181k miles.

paulh Posted January 27, 2011 Report Posted January 27, 2011 Not so sure about that. I think if your slave cylinder seals have gone the pedal will just go straight to the floor. Is there any evidence of fluid leaking out of the bottom of the clutch bellhousing? Quote
maz Posted January 27, 2011 Author Report Posted January 27, 2011 Yes there is evidence ofit. The clutch pedal still seems to be working ok, car is still drivable. Quote
sparky Paul Posted January 27, 2011 Report Posted January 27, 2011 Brakes won't fail Maz, clutch will go first as you suspect. If the the slave cylinder goes kaput completely and the the clutch fluid is lost, enough fluid remains in the reservoir to stop air getting into the brakes. Slave cylinder is mounted inside the gearbox bellhousing and is concentric type - it fits over the gearbox output shaft, which is bad news... the gearbox has to come off to change it. You can't change the seals, it's a throw-away job. Around Quote

sparky Paul Posted January 27, 2011 Report Posted January 27, 2011 It is only a recommendation, but the DMF is unreliable - most mk2 tdi clutch kits come with the DMF. There are, however, a few options... 1. You could fit a new clutch and DMF, cost for factor parts is around Quote
