Has anyone else built and used this type of brake bleeder:
http://www.bmw-m.net/TechProc/bleeder.htm

It's an ingenious idea. I tried it on two cars, both cases with the
original master cylinder reservoir caps and both times I had major
leakage around the cap. I pumped the bleeder to about 17psi.

Any idea what I'm doing wrong?

Thanks!

I use a similar setup. Sounds like you need a gasket to seal the cap to the
resevoir. If you can't find one the right size, check the plumbing section
at the hardware store for sheets of rubber you can cut to size.

I'd guess it's similar to the 'Eazybleed' in the UK. This supplies extra
caps in various sizes for different reservoirs and uses the spare wheel
for air pressure. You have to be careful to not cross thread the caps and
make sure all the pipes are a secure fit or fluid goes everywhere. But it
works very well if you take care.

I'm attempting to do the same thing except I took a spare master
cylinder cap and put a bicycle tube presta valve to it and pumped air
into my master cylinder to create the pressure. Much cleaner than
than the system you are trying to build. I also had air leaks
sufficent to render it useless and am trying to resolve.

And yes I've also used the gravity feed system (one wheel at a time)
and it did work. I am not positive that it would if you have a lot of
dirt in your system.

For it to work, you'll need an air reservoir. The spare wheel is ideal for
this. But reduce the pressure to about 15psi.

from ultimategarage.com. I got one for about $35 and installed a swivel
fitting, an air regulator and gage.
