If your parking brake isn't working correctly, it's likely due to one of these issues:
* Worn brake shoes: The rear brake shoes are the most common culprit. They wear down over time and need to be replaced.
* Low brake fluid: While less directly related, low brake fluid can affect the effectiveness of the parking brake. Check your brake fluid level in the master cylinder reservoir.
* Internal mechanism failure: A problem within the rear drum brake assembly, such as a broken spring or adjuster, could be the cause.
* Cable stretching (though less likely with self-adjusting): While the system is self-adjusting, minimal stretching could occur and might impact performance. This would usually be addressed when replacing brake shoes.
What to do if your parking brake is ineffective:
1. Check the brake fluid level: Ensure it's within the correct range.
2. Inspect the brake shoes: If you have some mechanical aptitude, you might be able to remove the rear drum and check the condition of the brake shoes. They'll need replacement if they're worn.
3. Test the parking brake lever: Make sure the parking brake lever is pulling up the correct number of clicks. Less than the expected number of clicks could indicate internal issues that may require a professional's attention.
4. Have a professional diagnose the problem: If you're not comfortable working on brakes, take your Sephia to a qualified mechanic. They can diagnose the problem and replace any worn or broken components. They have the tools and experience to properly assess the self-adjusting system. Attempting to adjust something you're not familiar with can damage the braking system.
Remember, a properly functioning parking brake is crucial for safety. Don't drive with a faulty parking brake.
