    2002 saturn l200 brakes pedal has went to floortwice in the last 6
    months after doing front pads. no leaks and did not open system.
    Anyone else have this problem. I would normally change the master
    cylinder. Its strange that the brake pedal is normal now.

    Any ideas?

    how is the fluid level and color in the brake reservoir?
    If the fluid is normal level and there are no visible leaks, I would flush
    the old fluid out and replace it until fluid at all the bleed ports runs
    Start with the right rear brake bleed port (furthest distance from master
    cylinder), left rear, right front and lastly left front. Often times some
    dirt or gunk interferes with master cylinder piston sealing. Sometimes you
    get lucky and are able to flush out any schmutz otherwise the master
    cylinder would have to be replaced.
    If you have ABS, it is a flow through system and does not have to be
    energized/cycled while bleeding the brakes.
