Here's a general procedure. Note: The exact location and method may vary slightly depending on your specific Caravan model. Consult a repair manual for your year and model for precise instructions and diagrams.
1. Safety First: Park the van on a level surface, engage the emergency flashers, and chock the wheels (use wheel wedges or bricks) on the opposite side from where you'll be working. Use jack stands to safely lift the van if necessary to access the mechanism easily. *Never work under a vehicle supported only by a jack.*
2. Locate the Cable: You need to find the parking brake cable where it connects to the rear brake calipers. This is usually located near the rear wheels, under the vehicle. You might need to remove some underbody plastic panels to gain better access.
3. Release the Cable: Once you locate the cable, you'll need to determine how to release the mechanism. There are a few possibilities:
* Adjustment Mechanism: Some systems have a small adjustment mechanism on the cable itself near the connection point. This might be a nut or a clamp that can be loosened to release the tension on the cable. Carefully try loosening this to release the brakes.
* Cable Disconnect: You may be able to disconnect the cable from the caliper. This might require using pliers or a wrench to release a clamp or connector. Remember which way the cable was connected for reassembly.
* Manually Moving the Lever: In some cases, you might be able to access the lever mechanism itself connected to the cable near the rear brakes, and manually move it to release the tension.
4. Test and Reassembly: Once you've released the brake, try to move the vehicle a short distance to verify that the parking brake is fully released. Then, carefully reassemble any parts you removed.
Important Considerations:
* Professional Help: This is a complex task, and it is highly recommended to seek professional help from a qualified mechanic if you are not comfortable doing it yourself.
* Damage: Attempting this without the right knowledge could result in damage to your vehicle's braking system.
* Repair Manual: A repair manual specific to your 1999 Dodge Caravan SE is invaluable. It will provide detailed diagrams and instructions that are far more reliable than general advice.
