However, some older models *might* have a manual adjuster. If your Grand Caravan *does* require manual rear brake adjustment (which is rare on modern vehicles), the process is usually as follows:
1. Safety First: Always engage the parking brake before starting any brake work. Disconnect the negative battery terminal to prevent accidental electrical shorts. Use jack stands to securely support the vehicle. Never work under a vehicle supported only by a jack.
2. Locate the Adjuster: This is usually a star-shaped wheel or a screw located on the back of the brake drum. You'll likely need to remove the dust cap to access it. The location varies depending on the year and model. Consult your vehicle's repair manual for the exact location.
3. Adjust the Adjuster: With the parking brake released, use a suitable tool (often a star-shaped wrench or screwdriver) to carefully turn the adjuster. Turn it clockwise (tighten) to tighten the brakes. Turn it very slightly, a little at a time. Rotate the wheel by hand after each small adjustment. If the wheel is difficult to turn, you've likely tightened it too much. Back it off slightly until the wheel turns easily but with some resistance.
4. Check Brake Pedal: After making adjustments, pump the brake pedal several times to verify proper adjustment. The pedal should feel firm.
5. Reassemble: Replace the dust cap and any other components you removed.
Important Considerations:
* Consult Your Repair Manual: This is the most critical step. The location of the adjuster, the type of adjuster, and the proper adjustment procedure vary significantly depending on the year and model of your Grand Caravan. The repair manual will provide specific instructions and diagrams for your vehicle.
* Self-Adjusting Brakes: As mentioned, most modern Grand Caravans have self-adjusting rear brakes. If you're having brake problems, the issue likely isn't a need for manual adjustment. Problems could include worn brake shoes, a sticking caliper (if it has disc brakes in the rear, which is less common), low brake fluid, or a leak.
* Professional Help: If you're not comfortable working on your brakes, it's best to take your Grand Caravan to a qualified mechanic. Brake systems are critical for safety, and improper repair can have serious consequences.
In short: Don't attempt to manually adjust your rear brakes unless you are certain your vehicle requires it and you have the correct information from your repair manual. If you're having brake issues, diagnose the problem first, and consider professional help.
