Tools you will likely need:
* Jack and jack stands: Essential for safety. Never work under a vehicle supported only by a jack.
* Wheel chocks: To secure the vehicle.
* Lug wrench: To remove the wheels.
* Socket set and wrenches: Various sizes will likely be needed. Check a repair manual for specifics.
* C-clamp or brake caliper compressor tool: To compress the caliper piston.
* Penetrating oil (PB Blaster or similar): To help loosen rusted bolts.
* Wrench for caliper slide pins: Often a 13mm or 15mm.
* Clean rags or shop towels: To clean up brake dust and fluid.
* Brake cleaner: To clean caliper surfaces.
* New rear brake pads: Make sure you get the correct ones for your E350.
* Repair manual specific to your 2006 Ford E350: This is crucial for detailed instructions and torque specifications.
Procedure (General Steps):
1. Safety First: Park the van on a level surface, engage the parking brake, and chock the front wheels. Wear safety glasses.
2. Raise and Support the Vehicle: Safely raise the rear of the van using a floor jack and securely place it on jack stands.
3. Remove the Wheel: Remove the lug nuts and take off the wheel.
4. Expose the Brake Caliper: You'll now see the brake caliper assembly.
5. Compress the Caliper Piston: Using a C-clamp or caliper compressor tool, carefully compress the piston in the caliper. This creates space for the new, thicker pads. Be careful not to damage the piston seal. Some pistons rotate as they compress. Consult your repair manual for proper procedure.
6. Remove the Brake Pads: Locate the retaining clips or pins holding the brake pads in place. Remove these, and the old brake pads should slide out.
7. Clean the Caliper: Use brake cleaner to thoroughly clean the caliper, slide pins, and caliper mounting brackets.
8. Inspect the Rotors: Check the brake rotors for wear and scoring. If they're excessively worn or damaged, they'll need to be replaced or machined.
9. Lubricate the Slide Pins: Apply a thin layer of high-temperature brake grease to the caliper slide pins before reinstalling them.
10. Install the New Brake Pads: Install the new brake pads, ensuring they're properly seated. Replace any retaining clips or pins.
11. Reinstall the Caliper: Carefully reinstall the caliper over the pads.
12. Reinstall the Wheel: Put the wheel back on and tighten the lug nuts. Don't tighten them fully yet.
13. Lower the Vehicle: Lower the vehicle to the ground.
14. Torque Lug Nuts: Tighten the lug nuts to the manufacturer's specified torque (found in your repair manual).
15. Repeat for Other Side: Repeat the process for the other rear wheel.
16. Pump the Brakes: Pump the brake pedal several times to ensure the pads are making contact with the rotors.
17. Test Drive: Take a short test drive to check the brakes. If you notice anything unusual (spongy pedal, pulling to one side), have the vehicle checked by a mechanic.
Important Notes:
* Brake fluid: You may need to add brake fluid after compressing the caliper pistons. Check your fluid level in the master cylinder and top it off if necessary.
* ABS sensors: Be careful not to damage the ABS sensors (if your E350 has them) located near the wheel hub.
* Wear: Carefully inspect all components for wear and tear. Excessive wear might indicate other problems.
This is a simplified guide. Always consult a repair manual specific to your 2006 Ford E350 for detailed instructions, torque specifications, and safety precautions. If you are uncomfortable performing this repair yourself, taking your vehicle to a qualified mechanic is the safest option. Improper brake repair can lead to dangerous situations.
