Tools you'll likely need:
* Jack and jack stands: Essential for safely lifting the car. Never work under a car supported only by a jack.
* Lug wrench: To remove the wheels.
* Wheel chocks: To prevent the car from rolling.
* Socket wrench set: You'll need sockets to remove caliper bolts, and possibly the rotor retaining nut or bolt (if any).
* C-clamp or rotor compression tool: This helps to compress the caliper piston to allow for rotor removal and installation.
* Wrench for caliper mounting bolts: Usually a combination wrench or socket.
* Penetrating oil (like PB Blaster): Helps loosen rusted bolts.
* Brake cleaner: To clean brake parts.
* Gloves: To keep your hands clean.
* New brake rotors: Make sure you get the correct ones for your car.
* Torque wrench: To tighten bolts to the manufacturer's specifications (crucial for safety).
* Wire brush: To clean up the hub.
Steps (General Outline):
1. Safety First: Engage the parking brake, chock the wheels, and use jack stands to securely lift the car. Consult your owner's manual for the correct jack points.
2. Remove the Wheel: Remove the lug nuts and take off the wheel.
3. Remove the Caliper: Locate the caliper mounting bolts (usually two). Spray penetrating oil on them if they're stuck. Remove the bolts and carefully remove the caliper. You may need to use a bungee cord or hang the caliper from something to keep it out of the way. Do not let the brake line hang freely; support it.
4. Compress the Caliper Piston: Use a C-clamp or caliper compression tool to slowly and evenly compress the caliper piston. This creates space for the new rotor. Be careful not to damage the piston seal.
5. Remove the Rotor: The rotor might be held on by a single large bolt in the center, or simply friction. If there's a retaining bolt, remove it. Sometimes the rotor is just pressed on. You may need to gently tap it off with a rubber mallet.
6. Clean the Hub: Use a wire brush to clean the wheel hub where the rotor sits, removing any rust or debris.
7. Install the New Rotor: Slide the new rotor onto the wheel studs. If there's a retaining bolt, install and tighten it to the correct torque specification (check your repair manual).
8. Reinstall the Caliper: Carefully place the caliper back onto its mounting bracket and secure the bolts, tightening them to the correct torque specification (check your repair manual).
9. Reinstall the Wheel: Put the wheel back on and tighten the lug nuts.
10. Lower the Car: Carefully lower the car using the jack.
11. Torque Lug Nuts: Torque the lug nuts to the manufacturer's specifications.
12. Test the Brakes: Carefully test the brakes before driving. Check for any unusual noises or vibrations.
Important Considerations:
* Brake Fluid: You may need to bleed the brakes after replacing the rotors, especially if you fully depress the brake pedal during caliper piston compression. Bleeding brakes is a separate procedure requiring a helper and a bleeding kit.
* Brake Pads: Inspect your brake pads while you're working on the rotors. They might need replacing too, especially if they are worn.
* Professional Help: If you are unsure about any part of this process, take your car to a qualified mechanic. Brake work is critical for safety.
Remember, this is a general overview. Consult a repair manual specific to your vehicle for detailed instructions and torque specifications. Safety should be your top priority when working on your brakes.
