Brakes problem
2003 Mercedes Benz SL55 V8 Two Wheel Drive Automatic 75000 miles

I went and had my car inspected for the state safety sticker and failed as the parking brake release was not working. I have not used it in probably two years. The mechanic showed me that when you pull the release handle in the dash, the handle pulls out without a cable attached. When pushing the brake lock down with your foot, it pops right back up. Any thoughts? I'm sure the dealer will change a big price as it is out of warranty. Thank you.
