If your parking brake isn't working correctly, the problem likely lies within the brake system itself, and adjusting a cable won't fix it. Here's what you should check:
* Brake Shoes: The most common issue is worn-out or damaged parking brake shoes inside the rear rotors. These shoes need to be replaced, not adjusted.
* Parking Brake Cables: While you can't adjust them externally, the cables themselves could be stretched, frayed, or rusted. This requires inspection and potential replacement.
* Return Springs: Weak or broken return springs might prevent the brake shoes from fully releasing.
* Rotors: If the rotors are severely damaged or warped, they could interfere with the proper functioning of the parking brake.
* Hydraulics (unlikely): Though less likely, a problem in the hydraulic system (like low fluid or a leak) could indirectly affect parking brake performance.
What to do:
1. Check the Parking Brake Lever: Make sure the lever is moving through its full range of motion and engaging fully. If it's loose or feels sloppy, there's a problem somewhere in the cable mechanism.
2. Inspect the Rear Brakes: This will require removing the rear wheels and inspecting the brake components, which is a more involved task requiring mechanical knowledge and tools. You'll need to see the condition of the parking brake shoes and the overall state of the rear brakes.
3. Consult a Repair Manual: A repair manual specific to your 1996 Impala SS will provide detailed instructions and diagrams for inspecting and replacing the components of the rear brakes and parking brake system.
4. Professional Mechanic: Unless you're comfortable working on brakes (and if you're asking this question, you likely aren't), it's best to take your car to a qualified mechanic. Improperly maintained brakes are a serious safety hazard. They can diagnose the problem and make the necessary repairs, including replacing worn shoes, cables, springs, or even rotors if needed.
In short, there's no simple adjustment. You need to troubleshoot the underlying cause of the parking brake malfunction. Don't attempt to fix it yourself unless you have the experience and tools. Brake safety is crucial.
