Here's a general procedure. Specific steps may vary slightly depending on the year and model of your Caravan. Always consult your vehicle's repair manual for precise instructions and torque specifications.
Tools You'll Need:
* Jack and jack stands: Safely lift and support the vehicle. Never work under a vehicle supported only by a jack.
* Lug wrench: Remove the wheel.
* Wheel chocks: To prevent the vehicle from rolling.
* Socket wrench and sockets: Various sizes depending on your Caravan's specific bolts.
* Pliers or a caliper piston compressor tool: To compress the caliper piston.
* C-clamp or brake caliper compression tool: To hold the caliper back
* Wrench for caliper bolts: Usually 14mm or 15mm, but check your vehicle.
* Hammer (optional): To gently tap the rotor loose (if stuck).
* Penetrating lubricant (like PB Blaster): To loosen rusted bolts.
* Torque wrench: To properly tighten bolts after reassembly.
* Gloves: To protect your hands.
Steps:
1. Safety First: Engage the parking brake firmly. Use wheel chocks on the wheels that remain on the ground. Wear safety glasses.
2. Lift and Support: Jack up the front of the vehicle and securely place it on jack stands.
3. Remove the Wheel: Remove the lug nuts and carefully take off the wheel.
4. Remove the Caliper:
* Locate the caliper bolts: These are usually on the back of the caliper.
* Compress the caliper piston: Use the pliers or a caliper piston compressor tool to push the piston back into the caliper. This creates space for the rotor to be removed. If the piston is difficult to compress, it may be seized and require more attention or professional help.
* Remove the caliper bolts: Carefully remove the bolts and carefully support the caliper. You can hang it from a wire or use a bungee cord to keep it out of the way. Do not let the caliper hang by the brake line.
5. Remove the Rotor:
* Inspect the rotor for rust or damage. Sometimes you need to gently tap the rotor with a hammer around its perimeter to loosen it from the hub. Be careful not to damage the rotor or the hub.
* Once loose, pull the rotor off the hub. It should slide off relatively easily.
6. Clean and Inspect: Clean the hub and inspect the rotor for wear. If you are replacing the rotor, proceed to step 7.
7. Install the new rotor (if applicable):
* Slide the new rotor onto the wheel studs.
* Make sure the new rotor is correctly positioned.
* Reinstall the caliper.
* Reinstall the wheel and tighten the lug nuts.
* Lower the vehicle.
8. Bleed the Brakes (Important): After reinstalling the caliper, you'll likely need to bleed the brakes to remove any air that may have entered the brake lines during the process. This is crucial for proper braking function. Consult your vehicle's repair manual for instructions on bleeding the brakes.
Important Considerations:
* Rust: If bolts are rusted, apply penetrating lubricant and let it sit for a while before attempting to remove them.
* Caliper piston: If the caliper piston is difficult to compress, it might be seized and need attention.
* Torque Specifications: Always use a torque wrench and tighten bolts to the manufacturer's specified torque. Incorrect tightening can damage components.
Again, if you are not comfortable performing this repair yourself, take your vehicle to a qualified mechanic. Brake work is critical for safety. Improperly done brake work can lead to dangerous situations.
