My GT has developed a noise in the drivers side rear wheel area. Whenever I hit a small bump, a clanging noise is coming from the rear brake area. I think it's the backing plate behind the rotor. In checking, I do not see any issue. Its tight, and doesn't appear to be touching anything. If I tap it with my hand, it makes the clanging noise, the left side does not make the noise. Any ideas on what it might be?
Thanks,
