Brake question.
I have a question about brakes. I just replaced my rotors and painted the brake calipers. In the process I disconnected my calipers from the brake lines. I put everything back as designed including the washers on both sides of the bolts.
When I put everything back togethers, I started bleeding the brakes with my mityvac. I have run at least four containers of break fluid through the systme but I am still getting bubbles. I have tightened all bleeders and double checked eveything. I don't have any line leaks and no puddles under the car. I have kept the master cylinder full of fluid. The front passenger side seems to be the worst. Any suggestions?

could be...
Very possible. The brake pedal is firm with no fade. I have pushed alot of fluid through it. I was thinking of replacing more parts but that may be it.

Put a section of hose from a bleeder into a jar of brake fluid and crack open the bleeder.
Then you can pump the brake pedal without worrying about pulling in air and you can see when bubbles stop comming out. Keeping positive pressure on the system will not allow air to be drawn in past the bleeder threads.

When I use my vacuum bleeder, I always get a line of small bubbles. I read int he manual that it was air being drawn in at the bleeder screw to vacuum hose connection and not too worry about it. If I get the wife to push the pedal, I don't see those bubbles.

Is the hose full of fluid?
I can't seem to get the hose to fill completely with fluid, so to speak. I have fluid flowing but not enough to fill the line

Update
It was the mity vac. I used Square's suggestion and did a manual bleed and no bubbles. Took it out for a test drive and it works like a charm... Thanks guys! The forum is one great place!!!

Very important! crush washers are a single use component, if you find yourself losing a little fluid at a time, replace them and rebleed!
I prefer gravity bleed to all other methods...may take a little longer but it is virtually 100% fool proof

Use teflon tape on your bleeder threads, if that doesn't work, replace the crush washers and buy speedbleeders while you're at it.
Positive pressure (pedal pumping) bleeding is always a more thorough method. There's even a phoenix tool that forces fluid into the system through the caliper (also positive pressure).
