I was driving on the Interstate and I heard a pop then the car could barely make 60 mph at 3k rpm. I got off at the next exit and parked. Both back wheels were hot as the dickens. I had it flat towed home. I was able to drive it up on the tow bed after it had cooled. I am entirely unfamiliar with brake repair (other than bicycles). I jacked it up and tried loosening the hose to see if that released it(it did not).
I can not tell for sure if the caliper is locked or the emergency brake. Short of taking off the caliper is there a way to test? Thanks for all replies.
