If your parking brake isn't working properly, it's almost certainly not a simple adjustment. The problem likely lies within the rear brake system itself and requires professional attention. Possible causes include:
* Worn brake shoes: The brake shoes inside the rear drums are worn down and need replacing.
* Worn or damaged parking brake cables: While you can't adjust the cables externally, they might be frayed, broken, or stretched.
* Contaminated or damaged rear brake components: Rust, dirt, or damage to other brake parts can hinder operation.
* Low brake fluid: Low fluid level can affect overall braking performance, including the parking brake.
* Problem with the parking brake lever/mechanism: Internal linkage problems within the parking brake lever itself can be a rare source of failure.
What to do:
1. Check your owner's manual: See if it provides any specific information about parking brake issues. It's unlikely to contain an adjustment procedure, but it might have troubleshooting tips.
2. Check the brake fluid level: Make sure your brake fluid is at the correct level in the master cylinder reservoir.
3. Have it professionally inspected: This is the best course of action. A mechanic can diagnose the specific problem and perform the necessary repairs, which may involve replacing brake shoes, cables, or other components within the rear drum brakes. Attempting to repair the parking brake yourself without proper knowledge and tools can be dangerous. The parking brake is a critical safety feature.
Do not attempt to "adjust" the parking brake by forcing the lever or using any other unconventional methods. This could damage the system further.
