You probably paid over the odds for the piece of shit plastic unit. I just
went and got a basic bleed kit for mine in the end, but was contemplating
importing the quality silverline kit version - which would work out better
than the eventual throwaway plastic unit - which isnt actually that less
expensive given the shipping fees etc.
A basic bleed kit ~ £5.

We've been using a plastic Mityvac here for some three years now, on
many different bikes - and cars too, come to that. Hasn't ripped
slipped or turned inside out yet, and has paid for itself in hours
saved and grief avoided many times over.

Useless. Especially in comparison, fucking useless.
I've used everything from total-loss (open nipple, apply pressure and
let fluid go) through bits of tube and fucking jam jars, bits of
rubber with valves in - right up to fully pressurised commercial
bleeding systems that force fluid through from the reservoir. The
plastic Mityvac works as effectively as the very best kit, which is
far more than I'd say about bits of rubber hose.

Exactly. Fine if you've got an assistant, specially one with a clue,
but damn awkward solo and virtually impossible if you're working on a
vehicle bigger than a bike.

I came unstuck with a car front brake. Had to change flexi hoses for
MoT and they wouldn't undo from the steel lines, so I ended up getting
my local motor factor (bless 'em) to make me up some lines in copper
(twenty minutes, tenner). Of course, the old lines had run the
reservoir dry by the time it came to fit the new ones.
I thought I was fucked. Air in the system from the top end, having to
bleed a complex system right through. Effectively, I did a fluid
change, working around the car one wheel at a time, with re-test
deadline looming. It took a couple of Mityvac reservoirs full, but
the little beast pulled clean fluid through to each wheel within a
couple of minutes - with zero spillage.
Job done start to finish within twenty minutes and I didn't even jack
the car up. That's worth a great deal to me in avoided grief and
time-consuming hassle, not to mention obviating the awful floppy pedal
on the road test.

AOL to that, brother PoshBoy.

He could stick an ear over the nipple and crack it gently. That would
work and there's a considerable reservoir to fill there too.

I will also stand up for the 'throwaway' plastic Mityvac. I've had mine
for years and haven't been especially gentle with it, yet it still works
as new. If you think the Silverline kit will be more durable I think
you're mistaken. If I ever have to replace my Mityvac, which I doubt,
I will definitely get another plastic one, it's a great tool.

How much do they cost? I've got to get my brakes bled in the next
two weeks to get an MoT or SORN the thing -- or sell it to someone with
more time than I.
