Here's a general outline, but remember this is not a precise guide and the specifics might vary depending on the exact nature of the brake failure:
1. Safety First: Make sure the vehicle is parked on a level surface and the vehicle is turned off. Engage the parking pawl (if the car has an automatic transmission) as an additional safety precaution. Chock the wheels behind the rear tires to prevent any rolling.
2. Locate the Emergency Brake Cable: You'll need to get under the vehicle. The emergency brake cable typically runs from the handle inside the vehicle, down through the floorboard, and connects to the rear brake assemblies. Tracing the cable from the handle will help you locate the connection points.
3. Identify the Problem: Determine *why* the brake is stuck. Is the cable frozen? Is there a binding point? Is there a problem with the mechanism at the rear brakes?
4. Attempt to Release Manually: Once you've located the connection points at the rear brakes, you might be able to carefully and gently release the tension on the cable using pliers or other tools. This requires a good understanding of the brake system and should only be attempted if you are familiar with automotive mechanics.
5. Lubrication (If Appropriate): If the cable appears frozen, you might try to apply a penetrating lubricant (like WD-40 or PB Blaster) to the cable and allow it to soak in for some time before attempting to release it.
Important Considerations:
* Risk of Damage: Forcing the system could break the cable, damage the brake mechanism, or cause other problems.
* Professional Help: This is not a DIY task for most people. The risks of improper repair outweigh the benefits in most cases.
* Vehicle Specifics: The exact location and release mechanism will vary slightly between model years and trim levels of the Suburban. Consulting a repair manual specific to your vehicle is crucial.
If you cannot release the emergency brake, do not drive the vehicle. Call a roadside assistance service or a qualified mechanic to have the problem addressed safely and correctly. Driving with a malfunctioning emergency brake is extremely dangerous.
