Brakes (see sig)

It can take a long time to build up pressure.

When bleeding, pump the lever half a dozen times before releasing the
nipple.

 

Not in my experience. My Mityvac has been used to do the brakes on my
Laverda, my Aprilia, my wife's Suzuki, our Fiat, a VFR750, a VFR400, a
Hyundai Accent, a Daewoo Matiz and a couple of hydraulic clutches as
well - and we've never had a problem with air getting past the threads
of the bleed nipple. Are you sure you hadn't screwed the nipple all the
way out?

Never had that happen.

Did mine just fine - the hydraulic clutch on the Fiat is a sod of a job
using normal methods & I can't believe how easy it was with the mityvac.

You reckon? I've been wishing I'd bought a mityvac years ago - the
amount of time I wasted & hassle I put up with because I wouldn't buy
things like that boggles my mind. These days if there's a tool to make
my life easier I'll buy it[1].

[1] Provided it comes decently recommended - my mechanic uses a mityvac
when he's working on brakes, if it's good enough for him...

 

I've had problems with my compressor driven bleeder; it will suck air
past the threads. Which is a pain in the latter stages of bleeding.

The solution has been to undo the nipple so it only just unseats. This
also has the effect of slowing it down a bit as the industrial bleeder I
have can empty a bike system in seconds.

I've used my Mytivac on an old Mini Cooper system, it was the only
mathod of bleeding the brakes that worked.
