More likely horribly misadjusted brakes. Or the right side not working at all. Yeah, the "kids" working at the shop probably never worked on a front drum brake car before and were clueless. As for the battery in the trunk, inexcusible. That could have burned the car to the ground. I admit I am no fan of front drums on cars but they do work when adjusted properly. I had a 65 Monaco with 11 x 3 drums up front that would plant your face on the dashboard when you tapped the brakes. I have also had misadjusted front drums and gotten myself into accidents with them. Don't accept it from them until it is perfect. Mike
