New brake calipers/No pressure
I replaced my old calipers with new ones today and now after bleeding them I have no brake pressure at all. I bled them several times but to no avail. But when I press the pedal down I hear a lot of air. What could this mean? Even before I installed the new calipers I was hearing an "air" sound.

Did you bleed at ALL 4 wheels, starting at the right rear then the left rear then the right front then the left front, and repeat if needed???? If not that may be the problem.

did you install with the bleeders on top? It happens!
Just trying to help. If just bleeding the fronts, passenger
side first. When doing all 4 - RR - LR - RF - LF.

Heres what happening now. I do have some brakes but just a little. With the engine running: When I first press the brakes it goes all the way to the floor, when I lift my foot from the pedal and press again there is a little bit or pressure, I can then pump the brakes and build up a little more pressure. Then if I take my foot off the pedal for a couple of seconds all the pressure goes away then the pedal back to floor when I apply pressure to it.

You still have air in the lines, I prromise...
How are you bleeding the brakes?
I use a small hose on the bleeder and run it into a Mt Dew Bottle (Cause I'm addicted to Mt. Dew) half filled with fluid. Have someone pump the brakes 4 or 5 times and hold it ONE INCH off the floor. (Not all the way to the floor) While they're holding it there you crack the bleeder and watch the bubbles run down the hose into the fluid. This prevents you from sucking air back into the bleeder. Then that person can let off the brakes and do it again.
Do this in the order that they described above. I usually do each wheel about 4 times each on the first round and then at least 2 more times on a second round.
Did you bench bleed the master cylinder? If not, that could certainly be the issue.
Jeff, while you're at it. NAME THIS BAND! lol

Yea I bench bled the master before installation. Im having my wife pump the brakes and then she holds them and I open the bleeder and then I close the bleeder. Im going to tomorrow morning and buying a vaccum bleeder from autozone. I might try your way also but with a Coke bottle.
And as for the band, I'm not sure but the guy on the top row in the middle looks like Kip Winger, so I'll say the band is Winger. But then again the guy at the bottom with the guitar looks like Eddie Van Halen. But I'm going with Winger. Final answer.
