My two years are up and I want to replace the brake fluid. I saw Writeme43's howto and thought a MityVac would be neat to have (I love gadgets too) so ordered one. Now here is where it gets ugly...
I hooked up the MityVac and pulled a vacuum but the very second I opened the bleeder screw - bubbles. I mean bubbles everywhere at the fitting. What is going on here? There is a tight seal around the hose and fitting, as I see it, so maybe the air is coming from around the screw threads?
I know it's not coming from an existing condition - my brakes were fine before. It's obviously I don't what I'm doing with this gadget so I simply went with the old method of bleeding brakes. I thought in its operation I could open the bleed screw and brake fluid would siphon out, as long as a vacuum existed, and I could add fluid all in one shot (never touching the brake lever). Am I wrong or have I missed something entirely?
