I haven't noticed it before but applying the brakes after driving thru snow I get an awful crunch sound. I have stopped the car a few times to look and it appears the wheel wells are clogged with slush but I don't know if thats whats causing it. After the crunching sound if i'm driving on a clear road there is no noise if I brake. Its much worse than say the crunch you get if the brakes are wet. Whats up with this?
