Ive posted this before, but maybe the subject wasn't very clear. Basically, after i turn on the ignition, i sometimes get the big BRAKE warning light come on (exclamation mark in a circle with brackets), it flashes, and beeps 3 or 4 times. It normally happens when the car hasnt been used all day, ie first time in the evening or morning, etc. It doesnt happen when driving, or when the cars heated up a bit. Any "more" clues...its buggin me.
