The rear brakes on my 200 lock up when ever the parking brake is used. Need to get a set that works. Reman from online run about $200 for a set.
I actually have two sets of rear calipers and neither work

Bought a rebuild kit and didn't help it.
It's only the parking brake not working, the unit itself helps stop the car.
