* Cable binding or seizing: The most common culprit. The cables can rust, become frayed, or bind within their housings.
* Brake shoes sticking to the drums: The brake shoes might be corroded or glazed, preventing them from releasing properly.
* Adjuster mechanism malfunction: The self-adjusting mechanism might be jammed or broken.
* Contaminated brake components: Dirt, mud, or moisture can interfere with the brake's operation.
Fixing it yourself requires some mechanical aptitude and basic tools. If you're uncomfortable working on brakes, take it to a mechanic. Brakes are critical safety components.
Here's a general approach, but specifics may vary slightly depending on your Voyager's configuration. Consult a repair manual specific to your 2000 Plymouth Voyager for detailed instructions and diagrams.
1. Assess the Situation:
* Attempt to release the parking brake: Make sure the parking brake lever is fully released. If it's stuck in the "on" position, try gently working it back and forth while applying slight pressure. Don't force it.
* Inspect the rear wheels: Check if one or both rear wheels are locked. This helps determine if the problem is on one side or both.
* Check the brake cables: Locate the parking brake cables where they connect to the rear brakes. Look for any obvious signs of damage, rust, or binding.
2. Attempt a Simple Release (If Possible):
* Lubrication: If you can access the cable mechanism, try lubricating the cables with a penetrating lubricant like WD-40 or a specialized cable lubricant. Let it sit for a while to penetrate before attempting to release the brake. This is often helpful for minor binding issues.
* Manual Adjustment (With Caution): Some Voyagers have a mechanism to manually adjust the rear brake shoes. This is usually a small wheel located near the cable attachment point. Refer to your repair manual for its location and operation. Only attempt this if you're familiar with this process; incorrect adjustment can damage the brakes.
3. More Involved Repairs (Often Requires Removing Brake Drum):
If lubrication and manual adjustment don't work, you'll likely need to access the rear brake assembly:
* Remove the rear wheel: Loosen the lug nuts, jack up the vehicle, secure it on jack stands, and remove the wheel.
* Remove the brake drum: You'll likely need to use a drum puller tool (available at auto parts stores) to remove the drum.
* Inspect the brake shoes and mechanism: Look for rust, corrosion, glazing, or any signs of damage on the brake shoes, springs, and adjuster mechanism.
* Clean and lubricate: Thoroughly clean all brake components. Use appropriate brake cleaner. Lubricate moving parts with brake lubricant (not WD-40, use a specialized product).
* Replace worn or damaged parts: Replace any severely worn or damaged parts, including brake shoes, springs, cables, or the adjuster mechanism.
* Reassemble: Reassemble everything, ensuring proper adjustment of the brake shoes. Follow your repair manual's instructions carefully.
* Re-check: After reassembling, test the parking brake several times.
Important Considerations:
* Safety: Always use jack stands when working under a vehicle. Never rely solely on a jack.
* Repair Manual: A repair manual specific to your 2000 Plymouth Voyager is crucial for detailed instructions and torque specifications.
* Brake System is Critical: If you're unsure about any step, take your Voyager to a qualified mechanic. Improper brake repair can lead to serious accidents.
This is a general guide. The specific steps might vary, so consulting a repair manual for your exact vehicle model is absolutely necessary. Improper repair can severely compromise your braking system and safety.
