1st, I apologize if this posted somewhere else; but I haven't been able to find it. It's annoying and a bit embarrasing riding slowly thru a parking lot and hearing the constant "ssssshhhhhhhh" from the front brakes accompanied by the occasional "chirp-chirp". If i apply a light pressure to the front brakes, the noise stops. And they do not squeal when I use the brakes, either. The only time they act up is when they're not used.... Is there a easy fix for this, or should I just turn up the radio? Maybe my pipes aren't loud enough?
