I don't know how anyone has gotten the Avalanche/Silverado parking brake problem resolved. I have fought with Chevy Corp and the dealership and both refer me to each other to resolve the situation. This has been going on for years. The US Government gave Chevy an out by only forcing Chevy to correct parking brake problems on standard transmissions due to the added safety issues with standards. My parking brake stopped working a couple of months after I got the truck but I didn't think it was that big of a deal until I found out Texas requires the parking brake working. Since the original problem was due to a Chevrolet defect, logically, it should be corrected by them or repair be reimbursed by them. I WOULD RECOMMEND EXTENSIVE RESEARCH BE PERFORMED BEFORE BUYING A CHEVROLET ANYMORE TO HOPEFULLY PREVENT PURCHASING A VEHICLE WITH NUMEROUS DEFECTS LIKE THE aVALACHE HAS GONE THROUGH. TAILGATE CABLES, CENTER PARTITION SEAL, AND PARKING BRAKE NOT WORKING SHORTLY AFTER RECEIVING THE VEHICLE. THEY DID REPAIR THE SEAL BUT ARE ADAMANT ABOUT NOT TAKING CARE OF THE DEFECTIVE PARKING BRAKE. ANOTHER DISAPPOINTTED CHEVY CUSTOMER.
