If your parking brake isn't working properly, the problem likely lies in one of these areas:
* Worn brake pads: The most common cause. The parking brake pads wear down just like the regular brake pads. They need to be replaced.
* Calipers: A seized or malfunctioning caliper can prevent the parking brake from engaging properly. This often requires professional repair or replacement.
* Parking brake cable (internal): Though less common with this design than with older cable-actuated systems, internal cable damage or stretching is possible. Diagnosing this typically requires a professional mechanic.
* Low brake fluid: While less directly related, low brake fluid can affect parking brake performance. Check your brake fluid level.
* Internal mechanism within the caliper: A part within the caliper itself may be failing.
What you should NOT do: Don't attempt to adjust anything externally. There's no external adjustment mechanism designed for user access. Doing so could damage the system.
What you SHOULD do:
1. Check the parking brake lever: Ensure it's engaging fully. Sometimes, the lever itself or the linkage may be faulty.
2. Check the brake fluid level: Make sure it's within the correct range.
3. Have a professional mechanic inspect the system: This is the best course of action if the parking brake isn't working correctly. A mechanic can diagnose the specific problem (worn pads, faulty caliper, etc.) and perform the necessary repairs.
In short, don't try to adjust it yourself. Get it checked by a qualified mechanic.
