[Shotimes] FW: [mr2] MityVac

[Russ M.]

  I've used a Mity-Vac to bleed brakes hundreds of times over the past
several years without any trouble whatsoever.    It's fast, it's easy, 
and it works perfectly.
  I originally began using it to make bleeding brake a quick, one-man
operation,  after having replaced a few too many master cylinders with
internally damaged seals due to pushing the pistons beyond their normal
range of travel into the accumulated crud/corrosion in the bore.
  
  You need to use one of the pointed fittings <inside> the bleeder
screw,  not over it or in place of it.
  Of course there will be a tendency to suck in air from the bleeder
threads...that's why speed-bleeders have sealent on them.   
    Remove and clean the bleeder screw
    Wrap it (threads only) 3-4 times tightly with teflon tape
    Thread it back in almost all the way
    Insert the pointed fitting/nipple and pump to 40-50psi 
    Tap caliper with a mallet while bleeding
    Tighten the bleeder screw just before container is full and while
you're still drawing out fluid.
