I have a 98 Chrysler cirrus lxi and something is wrong with the rear brakes. At first the parking brake wouldn't disengage, so I took off the center console and found the the brake cable had come loose from the brake handle. I released the tension on the cable and the parking brake released, but not completely. The wheels will spin now, but not as freely as they should. I tried the remove the brake drum but the adjustment gear will only move about 1 centimeter in either direction. How do I get the drum off?
