My parking brake doesn't. It's too simple not to work but nobody told it that.
Pull hard, the cable is tight, but the car still moves. We've inspected everything, adjusted, taken up the cable slack, installed new shoes, sanded the inside of the drums. It mostly holds now when parked, but is totally ineffective when tested from 5 mph or so.
My friend and excellent mechanic suggested new rotor/drums because "We've tried everything else...." and I 'm installing them in a few days. I doubt it will help but...
Side question: where do the 2 rear cables connect the sole front cable?
