Here's a general overview of the process. Specific steps and tools may vary slightly depending on the year and trim level of your Ford Five Hundred:
I. Safety First!
* Park on a level surface and engage the parking brake firmly.
* Use jack stands. Never rely solely on a jack.
* Wear safety glasses and gloves.
* Have a helper if possible.
* Obtain a repair manual specific to your vehicle's year and model. This will provide detailed diagrams and torque specifications crucial for safe and proper repair.
II. Tools You'll Need:
* Jack and jack stands
* Lug wrench
* Wheel chocks
* Socket wrench set (metric)
* Wrenches (metric)
* Brake caliper piston compression tool
* C-clamp (may be needed depending on caliper design)
* Pliers
* Wire brush
* Brake cleaner
* New brake pads
* New rotors (likely needed, as pads should almost always be replaced with rotors if they're worn enough)
* Possibly a caliper rebuild kit (if calipers are seized or leaking)
III. Steps (General Outline):
1. Prepare the Vehicle: Secure the vehicle, chock the wheels, and raise the vehicle using the jack and place it securely on jack stands. Remove the wheel.
2. Remove the Brake Caliper: This typically involves removing a retaining bolt or pin and possibly disconnecting the brake line (be careful not to damage the line). Carefully support the caliper to prevent the brake line from stretching or bending. Some designs have a slide pin that might require lubrication.
3. Remove the Brake Pads: The old brake pads should slide out. Inspect the caliper and slide pins closely for any issues.
4. Remove and Replace the Rotors: If your rotors are worn, remove them. These are generally held on by large bolts.
5. Compress the Brake Caliper Piston: Use the compression tool to push the piston back into the caliper. This creates space for the new, thicker brake pads. Be careful not to damage the piston seal.
6. Install New Rotors: Clean the rotor mounting surfaces thoroughly before installing the new rotors. Make sure they're seated properly.
7. Install New Brake Pads: Slide the new pads into place.
8. Reinstall the Brake Caliper: Carefully reinstall the caliper, ensuring it is properly seated and bolted securely.
9. Reinstall the Wheel: Tighten the lug nuts securely, but don't fully tighten them yet.
10. Lower the Vehicle: Slowly lower the vehicle to the ground.
11. Fully Tighten Lug Nuts: Use a star pattern to tighten the lug nuts to the manufacturer's specified torque.
12. Pump the Brakes: With the vehicle on the ground and the parking brake off, pump the brake pedal several times to engage the new pads.
13. Test Drive and Inspect: Take a short test drive to ensure the brakes are working correctly. Check for any unusual noises or vibrations. Visually inspect the brakes again after the short test drive to ensure everything is working and hasn't shifted or come loose.
IV. Important Considerations:
* Bleeding the Brakes: If you disconnect the brake line, you'll likely need to bleed the brakes to remove any air that may have entered the system. This requires a special procedure and tools.
* Caliper Issues: If your calipers are sticking or leaking, they may need to be rebuilt or replaced.
* Torque Specifications: Consult your repair manual for the correct torque specifications for all bolts and nuts. Over-tightening can damage components.
* Brake Fluid: Brake fluid is corrosive. Avoid getting it on your skin or paint.
Again, if you're not comfortable performing this repair yourself, take your vehicle to a qualified mechanic. Brake failure can be catastrophic.
