Stambecco Posted January 15, 2016 Share Posted January 15, 2016 Hello troops, 200Tdi 110 (1990 H) Slight dribble of fluid down the clutch pedal, I begun the procedure to replace the master cylinder, went to drain the slave with a tube etc. but nothing comes out at all when the pedal is pressed. The pot remains full, the cap is loose. The clutch functions perfectly so the pushrod must be working. Took the nipple out completely and it's dry, not blocked because I can see light through the hole. Any ideas? I expect it will be a case of draining it from the pipe and replacing the slave as well. Can't wait! Thank you very much, Julian. Quote Link to comment Share on other sites More sharing options...
vulcan bomber Posted January 15, 2016 Share Posted January 15, 2016 Because the master is not pumping anything cuz it's knackard? Quote Link to comment Share on other sites More sharing options...
Disco-Ron Posted January 15, 2016 Share Posted January 15, 2016 But the clutch works..... The only thing I can think is that the bleed hole in the slave is blocked..... its good practice to replace both at the same time anyway. ... For the cost of a slave just replace it. ... you won't be able to bleed it as it is anyway. .... and by the time you've dislodged some carp its bound to start leaking before long. ...

western Posted January 15, 2016 Share Posted January 15, 2016 master cylinder will be working up to a point, best to replace both, just make sure the new slave is fitted with bleed screw at top, or you'll never bleed it correctly. & always adjust the pedal assembly rod.

Stambecco Posted January 15, 2016 Author Share Posted January 15, 2016 Thank you all very much. Right you are, I will source a new slave and replace both of them. 591231 seems to be the one. Cheers. Quote Link to comment Share on other sites More sharing options...
western Posted January 15, 2016 Share Posted January 15, 2016 Yes, that's the one http://www.lrseries.com/shop/product/listing/1662/591231-CLUTCH-SLAVE-CYLINDER.html?search=591231&page=1 Quote Link to comment Share on other sites More sharing options...
Tanuki Posted January 15, 2016 Share Posted January 15, 2016 And when refitting the slave make sure you install it with the bleed-nipple at the top! I've 'helped-out' several "learning-challenged" types who've refitted the slave with the bleed-nipple at the bottom and after weeks of futile pumping discovered that fitted that way it can't ever be bled [remember, air-bubbles rise...]. Explaining to them the error of their ways comes at a price - usually a sesh at the local pub [with them paying my bar-tab of course: *warning* - I have seriously expensive tastes in single-malt whiskies].
