Guys I have an enigma here....

I recently bought two new tires to replace my rear ones. However, the mechanic switched my left and right wheels around in the process.

The car drives perfectly fine, but when I press on the brakes above 40 mph on turns, there's a loud vibrating noise, a harsh jutter in the brakes and steering wheel and it's pretty damn scary.

I can brake all day straight line and can turn w/o the traction control or braking w/o a problem.

Please help!!!!
