I have a "tinny" rattle when i go over bumps. If i am on the brakes it does not rattle. It just started a couple weeks ago. The large rotor backing plates are not lose or rattling. any other ideas on where to start looking? I have banged aroud on things and cant seem to find the culprit. My thought was that once the brake is engageed, even very lightly, it presurizes a hose, which may be rattling against something, but I am unable to find a lose hose anywhere either.

Any other thoughts on this?
thanks

 

It could be the pads rattling because of a sticky pin or a caliper could have worked itself a little loose. It could also be a loose brake line. Maybe one of the retaining clips broke or came free? I think a sticky pin is the most likely suspect.

 

Thanks, I checked the lines, nothign obvious. The pins is not one I would have considered. None of the external pads are loose, so it must be an inboard pad. Any ideas on how to find it with out pulling off all the wheels?

 

To close the loop on this, there us a bracket on the passenger side frame. It supports something, maybe. Fuel filter? But it was lose and rattling. I jammed some ruber shims in there. Seems to have fixed it. Thanks for the thoughts.
