If your parking brake isn't working correctly, it's almost certainly due to one of these issues and requires professional attention:
* Worn Brake Shoes: The brake shoes inside the rear rotors are worn down and need replacing. This is the most common cause of a poorly functioning parking brake.
* Internal Mechanical Issues: There could be a problem with the internal mechanism of the rear drum brakes, such as a broken spring, sticking components, or a seized cable inside the rotor.
* Low Brake Fluid: While less likely to be the sole cause of a non-functional parking brake, low brake fluid can indicate other issues. Always check your fluid level.
* Cable Issues (less likely): Although less common than problems within the drum itself, a frayed, damaged, or stretched cable *could* contribute to the problem. However, this is usually accompanied by other symptoms.
What to do:
1. Check your owner's manual: Your manual might offer specific details about your parking brake system.
2. Inspect the parking brake lever: Make sure the lever itself is moving freely and engaging fully.
3. Check the brake fluid level: Ensure the brake fluid reservoir is topped off to the correct level. Low fluid indicates a leak or other serious brake problem.
4. Take it to a mechanic: This is the crucial step. Adjusting a rear drum brake parking brake requires specialized tools and expertise. Trying to adjust it yourself can lead to further damage or injury. A qualified mechanic can diagnose the problem and perform the necessary repairs, which will likely involve replacing worn brake shoes, repairing or replacing other internal components, and potentially replacing cables.
Do not attempt to adjust the parking brake yourself unless you have extensive experience working on brakes. Improper adjustment can lead to dangerous driving conditions.
