I have a front brake problem I hope you guys can give me some suggestions on. I have a 2002 EC300 that has a front brake howl(horrible noise especially on long downhills) that has been an issue since the machine was new. I have chamfered the leading edge of the pads, sanded the pads, checked the pins,bolts etc. None of this has made a difference. I am out of ideas short of trying different pads or rotor but I don't want to spend money if it won't solve the problem. It of course has Nissin brakes. Any help would be appreciated.
