Hi all,

I attempted to bleed my freshly installed clutch hydraulics the other day, and couldn't get a good seal with the eezibleed on the top of the master cylinder.  This appears to be due to the sealing surface on the master not being machined very well, a 1/2" section of the sealing surface is quite rough.

After giving up on the eezibleed and bleeding it the old fashioned way I've managed to get the clutch working enough to drive it, but it feels like the clutch isn't fully disengaging.  Could this be because there isn't a good seal between the filler cap and the reservoir?  If so are there any quick fixes that I do without having to pull the master out again and replace it?  e.g. silicone on the sealing surface?

Thanks,
Robbie

Bleed the system again with the help of a friend there may be still some air in the system. make sure there is know air bubbles coming from the bleed nipple on the at the slave cylinder.

Sounds like it ain't bled completely................ so you are pressing the pedal and just compressing air rather than pushing fluid to move the slave cylinder rod.

The old fashioned way is IMHO the right approach. Connect a tube to the slave cylinder nipple, tube in a jar of old fluid, slacken nipple a wee bit and wait .............. just let the fluid run through on gravity, if you've had the master cylinder disconnected then you have to be sure that any air drawn in at the cylinder end has travelled through the pipework and out the bleed nipple  ......... keep an eye on the master cylinder level and top up as required. I've undone alot of good work in the past by not observing the last point

Normally that will do it ................ time and gravity is what's needed. Assuming of course (delicate cough) all your repairs are good .......... and you're not drawing air in from a join or whatever.

Good luck..........

Hi Robbie,

In my experience if you get a hand from someone and put the bleed bottle on the slave cylinder, top up the
master cylinder reservoir leave off cap. get your mate to pump the pedal up 5 or 6 times then hold pressure on the pedal.
when the pressure is on the pedal crack open the bleed nipple till the pedal hits the floor then close nipple, top up fluid then try pedal.
you may have to repeat this again but should work

cheers colin

As above!!
The last time I did this I recruited 2 friends; one to work the pedal & one to keep the reservoir topped up. It  made life much easier with an extra person topping the reservoir and made the whole process pretty straight-forward.
