I've recently acquired a new set of (aluminium) wheels, and at first they were fine, but now when I brake the rear lightly I can feel a shuddering/vibration through the bike. If I press the brake harder, 9/10 times, it will make a loud honking noise, which kind of sounds like an angry goose (i.e. it is not a squealing noise) These are rim brakes btw, as most threads I've searched are a similar problem but are with disc brakes, not rim brakes.
What I did was:
- Took pads out, cleaned them.
- Aligned shoes to braking surface
- Used a business card to toe in the brakes.
This seemed to stop it for a few rides, but the noise has come back again. Any ideas on what could be causing this? I am also using the correct pads as recommended by the wheel manufacturer (Shamal Mille, with Campy blue pads).
Note: An example of the noise can be found here:
