    Just put new pads, rotors and calipers on and now I have no pedal pressure. Also when I pump the pedal my idle become erratic.

    Hi Joe,

    You did not mention if you also flushed the break fluid and/or bleed the system to remove the air in the new calipers and lines. If you haven’t, bleed and flush the whole system with new fresh break fluid.

    To be honest I think the guy that was helping me was turning the bleeders the wrong way cuz he stripped the hell out of them and couldn’t get them open so we just bleed them at the line. I’ve done this with success on other vehicles so I figured it may work. But if that we’re the issue it wouldn’t explain why the brakes are affecting the idle would it?

    Joe,

    When you pump the break pedal you are indeed affecting the vacuum in the system. Remember the booster gets its vacuum from the intake manifold. If in my van I pump the break pedal repeatedly, it affects the idle of the engine to a certain degree.

    Bleeding each line at the caliper is you best shot to restoring breaks effectiveness.
