Hi Folks, Car stopped fine until it sat about a week in cold weather (without park brake). Went to back up, released brake and heard loud snap. Car rolled back fine. Every since then when applying brakes under normal stopping conditions there is a thumping from right-rear wheel. (Feels almost like a flat spot on tire - only present when braking). Any suggestions before I bring it in to my mechanic?
Cheers,
