Ever since I did my 240 mod, I have had a strange brake noise. The noise only appears at the last instant of stopping. Sounds like cutting a brake rotor without a band. The pads are brand new OEM, I really don't think it's the pads. I have had the wheel off 3 times looking for problem, but cannot find it. I just replaced the rubber peg in the bracket and a new spring clip for pads. This cured problem for most of a 10 mile ride, but the noise is back. Anyone have any ideas, I'm at a lost. Thanks, Skip.
