I have determined that the reason disk brakes squeak so loud is because the vibration is not dampened ever. It goes straight from the rotor to the hub. Metal on metal. The brake assemble itself goes straight to the frame. Metal on metal.
If you were to use a tough rubber washer, or even nylon and put them in between the rotor and the hub. As well as in between the brake assembly and the frame; wouldn't this stop most of the vibration in turn stopping most of the noise being distributed?
Please prove me wrong otherwise I'm going to go buy some nylon washers.
