    I believe I have a problem with the master cylinder of a 1995 Saturn SW2
    The brake pedal goes almost to the floor when I brake during driving.
    With the engine off, the brakes pump up 'ok' ...
    When I then start the engine (with pressure still on the pedal), the
    pedal goes almost to the floor. The car has ABS.
    Neither the service light nor the ABS light comes on ... although the
    ABS light came on a couple of times a few weeks ago before I had a brake
    peddle problem.

    I found a rebuild master cylinder ... the problem is that I have never
    changed a master cylinder on a car with ABS ... Anyone have any
    suggestions or comments?

    I appreciate the note. I have not started anything yet. I may see if I
    can get it to autozone ... I have to check what their status is on Sunday.

    Just curious, what makes you think its a master cylinder instead of, say, a
    split brake line?

    In Feb, the brake pedal went to the floor in my fathers old ride(92 LeSabre).
    Upon inspection I found that the inside of the right front tire was covered in
    brake fluid. I pulled the tire and found that the rubber hose running from the
    steel hose near the frame to the caliper itself had dry rotted and split
    through. Earlier this month, he told me the pedal went to the floor again, and
    I guessed it was probably the right side rubber hose........sure enough.

    I would check the brake system over before you change the master cylinder.

    I have not done a thorough check ... haven't had access to a ramp or
    lift yet; but it apparently has not leaked any brake fluid ... the
    reservoir if full.

    Ah ok. A buddy of mine's chevy had a bad master cylinder. You'd be driving the
    car and all of a sudden the brake pedal would go to the fun
    fun. But it could be fixed by pumping the brakes.
