1995 Cadillac Deville Change Rear Brake Pads

You don't take the bar out. To just change the pads, remove the bottom caliper bolt(12mm), and the park brake cable bracket bolt(14mm). Rotate the caliper up on the slide pin, and the pads can be removed and replaced. You will need to turn the piston in to recover the clearance for the new pads.

Must jack the car up. Place blocks under the main spring and let the jack down so that the car's weight is on the spring and that action rotates the stablizing bar down and out of the way of the emergency brake arm which is connected to the caliper. Then I am able to fully rotate the caliper up, so that the old pads can be removed.

Sounds like you got it whipped. I usually perform the service on a hoist that lifts the body, and the suspension hangs.
