    I think that my M/C has gone in my truck first I would like to confirm that this is the problem.
    I started to find that every once in a while the pedal would sink to the floor b4 I'd stop. It has steadily gotten worse since then and now even after I pump the pedal to restore pressure if I hold the pedal down it will gradually lose pressure until the pedal hits the floor.
    Is this the M/C?
    If so do I just replace it with another one? Or is there an upgrade I can replace it with? And is this a part that I should replace with a new part only or is used fine?

    I need to make sure that this is all I need to pick up as the pick a part is over an hour from my house.
    Thanks in advance. ~Max

    Mine is having the same problem, but I was thinking it was the brake booster since your losing pressure (vacuum loose). If someone has a better answer, please chime in, i'm tired of driving my burb with sketchy brakes /forums/images/graemlins/shocked.gif

    yes it sounds like the m/c is going bad they are cheap replace it and bleed the brakes good and then you should be good to go also check to make sure you have a good vacuum line going to the booster and that its got a good seal and isn't leaking vacuum at the fittings

    when a vacuum booster goes bad it is hard to press on the brakes but they will not go to the floor, sounds like your problem is a bad master cylinder or leaky wheel cylinders leaking all your brake fluid out if your fluid is not low it is your master cylinder. Always buy brand new parts for brakes, they are cheap when it comes to hospital/funeral bills... /forums/images/graemlins/thumb.gif

    About the only thing i'd use used, in brake parts, are drums, rotors & calipers. And these can be bought new, and cheap at most auto parts stores.
