If your parking brake isn't working correctly, the problem likely lies elsewhere and requires professional diagnosis and repair. Possible causes include:
* Worn-out brake pads: The most common reason. The pads need replacing.
* Problems with the parking brake cable: Although self-adjusting, the cable itself can fray, stretch, or become disconnected.
* Internal issues within the rear calipers: A malfunctioning caliper mechanism could prevent proper engagement.
* Low brake fluid: This isn't directly related to the parking brake, but low fluid affects the entire braking system.
Instead of attempting to adjust the parking brake yourself (which isn't possible in this car's design), take your Intrigue to a qualified mechanic. They have the tools and expertise to properly diagnose and fix the issue, ensuring your safety and the proper function of your braking system. Ignoring a malfunctioning parking brake is dangerous.
