Hi Jeff,
Kevin is correct that the master cylinder slopes with the fluid outlet
at the top, so when you fill the system from below through the bleed
nipple it's difficult to get all the air out. The Europa brake bleeding
kit contains a small aluminium reservoir that screws into the fliier
hole in the master cylinder, and this really makes the process much
easier - it was the only way I could successfully bleed the system. Just
fill from the bleed nipple with the supplied syringe until the fluid
level is about half way up the reservoir, tighten the bleed nipple, then
pull the brake lever until no more air bubbles through the reservoir.
Then slowly release the brake making sure that the fluid level in the
reservoir stays above the bottom. The whole system should then be filled
with fluid. Suck the excess from the reservoir with the syringe, remove
and screw the cap back on and you're done. It's a 5 minute job with the
kit and I would really recommend it. No financial interest !

Hi Jeff,
My mono-wheel brake was leaking a bit of fluid and not holding
pressure well. Turned out to be the O-ring seal. We removed the brake
---From the disc and used a rubber tipped compressed air gun to push the
"puck" out of the slave cylinder. Then we saw the o-ring to replace. It
looked like it was leaking from the bleed screw simply because the bleed
screw is the lowest point to drip from.
When the mono is sitting tail down the master cylinder in the tunnel
is at an angle with the filler low. I needed to raise the tail (or
unmount the master cyl) to get the air out.
Messy job eh?
Kevin
