Well I just replaced my clutch and figured it was time to deal with this, i've never had great pedal pressure and figured it was probably the slave cylinder leaking (which was at least part of it) so I replaced that and bled the whole system repeatedly, but still I'm not getting a whole lot of back pressure and I can't find a leak anywhere. Is there any chance replacing the MC might help and if so how involved of an operation is that (anyone have a link to a write up?) Just figured I might try it if it was easy, but I've only ever replaced the slave cylinder before so I'm kinda out of ideas here.

 

See if the master is leaking inside the car underneith the dash.Also when u bleed the slave did u fill the MC then put the cap back on then pump and bleed several times?

 

Yeah I bled it thoroughly. The MC looks like their might be a slight leak but not substantial. I might replace it anyway, is there a write-up for it?

 

Mine is the same way, replaced complete clutch assy, and slave.....still do not have what I would call good or great pedal pressure....

 

any sort of leak will cause a spongy pedal.
