Recommended Tools; Mityvac vacuum bleeding thing.

Heaven only knows what it's called...

But I bought a Mityvac brake bleeding kit from Hein Gericke last
weekend, it took me about 20 minutes using this to bleed the front and
rear brakes on a bike following rebuilding the calipers.

Recommended; seriously it's a fantastic piece of kit.

Attach it to the bleed nipple, pump the handle a few times, open the
bleed nipple and then top up the fluid reservoir regularly. That's it.
No pumping the brake lever and opening/closing the bleed nipple.

If I break it I'll definitely buy another.

 

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.

 

Thanks for that, however I think I knew that. The one-way valves have
always been unsatisfactory in my experience because they are subject to
air leaks so you've still got to fiddle around with the bleed valve and
pump the brake lever.

I've bled plenty of brakes conventionally over the last 25 or so years,
however bleeding an empty set of brakes is:

a) time consuming
b) sometimes difficult to do when you need to pump the lever with one
hand and open the bleed valve with the other.

Using the mityvac, bleeding front and rear brakes (after having removed
the calipers and rebuilt them) took 20-30 minutes including bolting the
calipers on the bike.

I'd rather spend a little money on something that makes a time
consuming, awkward task easier.

Anyway, have you ever used a vacuum bleeding unit?

 

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.
