Clutch issue

[Ianb]

Finally got my M50 converted cabby ready for MOT, and as i went to back out of the garage the clutch suddenly disengaged even though my foot was firmly on the pedal. Pumping the pedal can just about allow me to engage first but a second later with my foot hard on the clutch pedal the car launches forward.... . It's using an E30 master and i believe an e36 slave ( shorter than the E30 one ). Does anyone know if this is likley to be master or slave and am i using the right parts (i was working in a prev e30 shell so my guess is i am). it seems odd that it would be the master as no leakage is evident but pedal seems a bit low and the first half press appears tb doing nothing.
Any suggestions would be appreciated.
Thanks

key question.. what box are you using?
e30 box or e36?

[Ianb]

Good point, it's an E36 box.

Sounds like standard Master Cylinder to me. If you havnt changed either for new, nows the time to do both

[Ianb]

Thanks ( as usual Dan ) Now i just need to find a little rubber person who don't shave yet in order to get at the bloody thing

i got a m20 new clutch flywheel fitted about 3 months ago, new slave and now just feels like the bitting point seems to be higher than it was than when fitted. is this normal? never had a new clutch fitted ever to a car ive had so dont know the norm

In my M50 I've M20 flywheel,clutch , mounted with e36's gearbox, and sometimes when I push hard the clutch pedal, makes a noise...even in neutral position ...

bearing needs to have 5mm put on it. if u check your slave bet the pin has been pushed out, and the noise is a sqeek i beat at the bottom of the pedal
