There really should not be any adjustment necessary, the parking brake is self adjusting. When you first install new pads It may take several puls of the lever to get them set up.

The cables MUST be absolutely free moving, for the system to work.

The adjustment as pads wear is inside the caliper itself and it is automatic, there is a little lever on the caliper and it moves the pads ahead every time it is pulled. This lever can become sticky and not return after it is pulled. you can free it up by removing the lever and then removing the rubber dust sheild behind it. Then you clean and lubricate it.
When all is moving freely, the arm should spring back against a hard stop each time the cable is pulled.

There is an adjustment on the cables under the car, just behind the centre console. It normally does not need adjusting unless you replace the cables themselves.
To check the adjustment, you need to make sure that the little levers on the rear calipers are fully returned to their rest position, and make sure the handle inside the car is down. Then adjust the nut to take up the slack in the cables.

I dont think that they can screw up the calipers inside. I have had them apart and there is really nothing to bust. I suspect very strongly that the levers on each caliper are not moving freely.

Most places dont understand all this, even the dealers, so they sell you new cables and calipers. I know for a fact that you can make it all work if you get everything moving freely.
