  • 60 Hawk Brakes or NOT

    OK guys here is the deal, I have all new Hoses, lines, wheel cylinders, MC and a rebuilt Hydro-Vac. I have bled the system every which way from sunday. There is no air in the system. The problem is that the first press of the pedal results in NO brakes or pedal pressure, the second stroke is better and the third is great. The Master cylinder is new, not a rebuilt unit, I picked it up last year in york.
    I have searched all the past post and I did not find this problem any where. Any thoughts?

    I do not think pumping them is a good deal

    Three things come to mind:
    Did you bleed the booster?
    Did you bench bleed the master cylinder?
    Did you adjust the brakes up?
    This by no means covers all bases but it is a place to start

        The only other possibilities I can think of is a defective master cylinder, incorrect free play (should be about 3/8ths of an inch at pedal) or you are sucking air back in when the pedal is released somewhere in the system.

          Sure SOUNDS like air in the system. Those Hydro-Vac's are heck to bleed. Can you bypass it and see if you can get the brakes to work properly? If you can, at least you have localized the prob.

            Once you get good pedal, hold it firmly for 30 seconds or so... if it slowly sinks to the floor, I'd bet bad M/C; if it stays, I'd bet adjustment.

            Remember, drum brakes should actually have a little drag to be adjusted right; you might have to adjust a few times at first till the shoes get seated.

            That's about all I've got to offer... good luck!
