Here's a breakdown of troubleshooting and potential solutions:
1. Identify the Problem:
* Is the cable frozen? This is the most likely culprit, especially if you live in a cold climate. Rust and moisture can cause the cable to seize inside its housing.
* Is the cable frayed or broken? A severely damaged cable will prevent it from releasing.
* Is the mechanism at the brake drum seized? The parking brake mechanism itself might be rusted or jammed.
* Is the emergency brake lever not releasing fully? Check the lever itself to ensure it isn't stuck or binding. Sometimes, there's an adjustment at the lever.
2. Troubleshooting Steps:
* Try to release the emergency brake lever slowly and carefully: Gently work the lever back and forth, applying slight pressure and listening for any resistance.
* Check the parking brake cable: Locate the cable leading to the rear brake drum (you may need to access it from under the car). See if you can manually move the cable. If it's stiff or frozen, you might be able to work some penetrating oil (like PB Blaster) into the cable housing. Let it soak for a while before trying again.
* Lubricate the cable: After applying penetrating oil, you may need to work the cable back and forth to help the lubricant penetrate.
* Inspect the brake drum: If you can access the drum (it may involve removing the wheel), inspect the mechanism inside for rust or obstructions. Again, penetrating oil might help free things up. You may need a hammer and punch to carefully break loose any rusted components. However, be extremely careful not to damage the drum or mechanism.
* Check the emergency brake lever adjustment: Some models have an adjustment nut at the lever's base. This allows for fine-tuning the brake's engagement. Tightening it too much can make the release difficult.
3. When to Seek Professional Help:
If you've tried the above steps and the brake is still stuck, it's best to take your car to a qualified mechanic. They have the tools and expertise to diagnose and repair the problem properly. Forcing the mechanism could lead to further damage and potentially a more expensive repair.
Important Considerations:
* Never try to force the brake mechanism. This could lead to damage that is more costly to repair.
* Safety is paramount. Work on the vehicle on level ground with the emergency brake engaged (on the other side, if possible). Use wheel chocks for added safety.
* If you're not comfortable working on your car, don't attempt to repair it yourself. It's always better to be safe than sorry.
By systematically checking each potential problem area, you should be able to diagnose and hopefully fix the issue. Remember to prioritize safety and seek professional assistance if needed.
