Still trying to cure the noise from the rear disc brake

The replacement Swisstop pads came today, but my hopes that they would clear the noise were unfounded, and when I removed the old pads and examined them I found they were already badly damaged after only 300 miles

There is clear physical damage along the bottom edge of this pad, not normal wear

And the damage to the bottom edge of the second pad shows it has literally been hammered.

The obvious conclusion is that there is something wrong with the rotor, so I have sent off for a new one, which should hopefully finally solve the problem.

On the credit side the braking effect from the swisstop pads is far superior to the originals.,
