Bleeding Brakes using MityVac

Bleeding Brakes using MityVac
I tried using a MityVac to bleed my brakes and I keep getting a million little bubbles instead of a steady flow of brake fluid into the container. The tube on the brake bleeder is tight. I bled that one caliper the old school way and fluid came out like it should. Is there a trick to using this?

it is most likley the fitting of the hose over the nipple. Even though it looks tight they still leak. Or it could be coming around the threads if you backed the nipple out far enough..(too far)
It usually takes a steady 20 inches of vaccum for me to pull fluid to the right rear caliper on the cars. Fronts are quicker. But if the old school way works better for you go with it. But personally my mightyvac does the same thing and it works just fine. Maybe i am just used to it though after all these years
Also you may want to check the tube itself to make sure there are no pinholes in it. I have had that happen before. It will always leak air in then.

I did it old school and ran a hose from the screw into a container of brake fluid, a few pumps to get the air our, tighten the screw, and rock hard for me. I didn't turn the screw more than 1/2 to 3/4 turn either.

I had the same experience with the Mityvac. However, I bought speedbleeders instead - but I will try the wheel bearing grease trick on my Maxima. I tried using teflon tape, but that got sucked in and leaking, nearly getting into the system. At least the grease will dissipate.

I'm a big fan of Speedbleeders - crack the nipple, hook up the hose, and pump away at the brakes. Simple and easy, and they're dirt cheap too.
But, I have seen some instances where you weren't getting ANYWHERE until you hooked up a vacuum pump to get things movin'. Those are really fun!
