Pontiac Repair: 2002 Grand Prix Parking brake, brake rotor replacement, caliper brackets


Question
How do I adjust the parking brake. I have replaced the disc pads on all wheels. I see a cable with what looks like an adjuster on it. I had someone at a "brake repair" place tell me that it couldn't be adjusted because it is 4-wheel disc.
