Tools You'll Need:
* Jack and jack stands: Essential for safety. Never work under a vehicle supported only by a jack.
* Lug wrench: To remove the wheel.
* Wheel chocks: To secure the vehicle.
* Socket wrench and sockets: Appropriate sizes for your lug nuts, caliper bolts, and possibly the parking brake cable.
* C-clamp or rotor puller: To remove the rotor if it's stuck. A good quality puller is preferable to avoid damaging the rotor or hub.
* Penetrating lubricant (PB Blaster or similar): Helps loosen rusted or seized bolts.
* Wrench for the caliper mounting bracket bolts (if needed): Some models require removing the caliper bracket.
* Clean rags or shop towels: To keep things clean.
* Gloves: Protect your hands.
Procedure:
1. Safety First: Park the vehicle on a level surface, engage the parking brake, and chock the front wheels. Raise the rear of the vehicle using the jack and securely support it with jack stands. Remove the wheel.
2. Inspect the Brake System: Observe the caliper, pads, and rotor for any obvious damage or wear.
3. Release the Parking Brake: If your vehicle has a separate parking brake cable connected to the rear calipers, you may need to loosen it. Consult your repair manual for the location and procedure.
4. Remove the Caliper: There are typically two bolts securing the caliper to the caliper bracket. Spray penetrating lubricant on these bolts and allow it to sit for a few minutes. Use a socket wrench to carefully remove the bolts. Support the caliper with a bungee cord or wire to prevent it from hanging by the brake line. Do not let the brake line hang freely or it could be damaged.
5. Remove the Parking Brake Cable (if applicable): If the parking brake cable is still attached, carefully disconnect it. Your repair manual will show exactly where and how.
6. Remove the Rotor: Sometimes the rotor will simply slide off the hub. If it's stuck, use a rotor puller or a C-clamp to carefully pull it off. Apply pressure evenly to avoid damaging the hub. Tap gently with a hammer if needed but avoid damaging the rotor or hub.
7. Inspect the Hub: Inspect the wheel hub for any damage or rust. Clean it thoroughly.
8. Reassembly: Once you've completed your work on the rotor (replacing, cleaning, or machining), reverse the steps to reassemble the brake components. Make sure to tighten all bolts to the manufacturer's specifications (found in your repair manual).
9. Bleed the Brakes: After reassembly, you may need to bleed the brakes to remove any air that may have entered the system. This is crucial to ensure proper brake function. If you are unfamiliar with bleeding brakes, consult a repair manual or professional mechanic.
Important Considerations:
* Rust and corrosion: Older vehicles often have rusted or seized components. Penetrating lubricant is your friend.
* Torque specifications: Use the correct torque specifications for all bolts to prevent damage. Too tight, and you risk stripping threads. Too loose, and components may become loose.
* Brake pad wear: While you're at it, inspect the brake pads. Replace them if necessary.
* Professional assistance: If you are not comfortable performing this repair yourself, it's always best to consult a qualified mechanic. Brake systems are critical for safety.
This guide provides a general overview. Always refer to your vehicle's specific repair manual for detailed instructions and torque specifications. Improper repair can lead to brake failure, so proceed with caution.
