Here's a general outline. Specific steps may vary slightly depending on your exact model and trim. Always consult your vehicle's repair manual for precise instructions and torque specifications.
Tools You'll Need:
* Jack and jack stands
* Lug wrench
* Wheel chocks
* Socket wrench set (metric)
* Ratchet
* Brake caliper piston compressor tool (essential!)
* Torque wrench
* Wire brush or brake cleaner
* Penetrating lubricant (like PB Blaster)
* Safety glasses
* Gloves
Steps:
1. Safety First: Park on a level surface, engage the parking brake firmly, and chock the wheels opposite the ones you're working on.
2. Remove the Wheel: Loosen the lug nuts slightly with the lug wrench before jacking up the vehicle. Jack up the truck and securely place it on jack stands. Completely remove the lug nuts and take off the wheel.
3. Remove the Caliper:
* Use a socket wrench to remove the caliper mounting bolts. These are usually 14mm or 15mm.
* Carefully remove the caliper assembly. You may need to gently pry it away from the rotor. Do not let the caliper hang by the brake line; support it with a wire or bungee cord to prevent damage to the line.
4. Compress the Caliper Piston:
* This is the crucial step. Use the caliper piston compressor tool to push the caliper piston back into the caliper bore. This creates space for the new, thicker rotor. This is often the most challenging part for beginners. If you're not sure how to use the tool, look up a video online for your specific tool or type of caliper.
5. Remove the Rotor: The rotor may be held in place by a single bolt or simply press fit onto the wheel hub. If there's a bolt, remove it. If it's press-fit, you may need to gently tap it off with a hammer and punch, working your way around the rotor evenly. Be careful not to damage the wheel hub.
6. Clean the Hub: Use a wire brush or brake cleaner to thoroughly clean the wheel hub mating surface where the rotor sits. This ensures a good, even contact between the hub and the new rotor.
7. Install the New Rotor: Carefully slide the new rotor onto the wheel studs. If there's a centering bolt, install it. Make sure it's flush against the wheel hub.
8. Reinstall the Caliper: Mount the caliper back onto the caliper bracket and tighten the mounting bolts to the manufacturer's specified torque.
9. Reinstall the Wheel: Mount the wheel and tighten the lug nuts in a star pattern to ensure even pressure. Then lower the vehicle to the ground and fully tighten the lug nuts.
10. Torque the Lug Nuts: Use your torque wrench to tighten the lug nuts to the manufacturer's specified torque (found in your owner's manual or a repair manual).
11. Repeat for the Other Wheels: Follow the same steps for the remaining wheels.
12. Test: After installing all new rotors, pump the brake pedal several times to ensure the brakes are working properly. Test drive the vehicle carefully.
Important Considerations:
* Brake Pads: Inspect your brake pads while you have the calipers off. If they're worn down, replace them at the same time. It's more efficient and cost-effective to do this all at once.
* Torque Specifications: Incorrect torque can lead to brake failure. Always use a torque wrench and follow the manufacturer's specifications.
* Bleeding Brakes: In some cases (though unlikely after just replacing rotors), air may get into the brake lines. If your brakes feel spongy after the replacement, you may need to bleed the brakes.
If you're uncomfortable performing this task yourself, it's always best to take your vehicle to a qualified mechanic. Brake work is crucial for safety, so don't hesitate to seek professional help if needed.
