My car had been sitting idle in the garage for about a week. I hopped into the car, started the engine and put the car into reverse. As I was backing out of the garage, I heard a kind of loud "clunk" sound like something was braking free. It didn't sound good. I investigated and couldn't visibly find anything wrong w/ the car, so I proceeded to back out and drive. It drove fine and I didin't notice anything. The only thing I can think of was the e-brake had gotten slightly rusty and didn't release properly. Any input would be appreciated.
