Need some help with my disc brakes. Shimano resin pads. Rear brake works fine. Front brake is giving me trouble. To start, it has about half the stopping power of the rear brake. But when I try to really use it, it makes a sound like an air horn. And when starts to honk it brakes even worse.
I have tried isopropyl alcohol, acetone and sandpaper on both the pads and rotors (and all three at once). Nothing seems to make any difference. I have tried gentle and aggressive bedding. Both cases the rotors are quickly covered with a dark powder.
The only bright side is I have a little something extra when people can't hear my bell. Scared the crap out of a teenager yakking on the phone in the middle of a bike path.
