So yesterday it rained in Chicago, and normally my car does just fine in the rain.

I started noticing weird break pedal response. The pedal would sometimes loose a very little amount of "fight back". I would not lose any breaking power or have a problem stopping. This really dint bother me much as i figure it may just be me.

Only thing is, later that day the ABS and TSC (off) light came on, indicating that I no longer have anti-lock breaks.... Hmmm. So I turn the car off and back on. The light now goes away. The light will then come back on shorty. It comes and goes.

The problem just started yesterday. Any suggestions on what it might be? Possible low fluids? A sensor? Sorry if this description is a little vauge. Im a little hungover right now

Thanks!
