    About six weeks ago I developed a brake problem wherein I had to pump the brakes a couple times to get pressure in the pedal. Basically the first touch of the brakes when the car is cold, the pedal would go to the ground (but still stop the car if it was rolling), then after a couple quick pumps the pedal would have nice high and tight pressure. The pedal would maintain this pressure if I was constantly on the brakes, however if I was off the brakes for more than 30-60 seconds I would have to pump them up again.

    The problems first came about after using a friends power bleeder to flush the brakes (never went over 20psi). Since then I have installed speed bleeders and done 3 complete flushes of the system, so I highly doubt that the problem was air in the system.

    My theory was that the MC was damaged during the power bleeding. So the new MC should arrive today.

    Here's the catch... the problem disappeared yesterday.. no more pumping. Brakes are solid.

    Any ideas? Is it just a trick and the MC is about fail horribly while braking on the ramp from 85S to 75N and kill me?

    There's always the emergency brake :)

    I am not entirely sure what could be causing this, you could be on a hunch with the MC but maybe there's another underlying issue. Are your brake lines good, no holes, etc? Were you ever experiencing fluid loss?

    No fluid loss at all, brake lines are solid...

    Air in the system. Or you have wheel bearing issues.

    Winner winner chicken dinner!!!

    I just had the right front wheel bearing replaced at SoG yesterday because it was completely shot. I neglected to mention that little fact :hsugh: Just talked to Jonathon about it in fact, it all makes since now.

    Anybody need an new in the box OEM MC for an '01 RS?
