Tools You'll Likely Need:
* Jack and jack stands: To safely lift the truck.
* Lug wrench: To remove the wheels.
* Wheel chocks: For added safety.
* Sockets and wrenches: Various sizes depending on your caliper bolts, lug nuts, and potentially rotor retaining hardware (some models use a retaining bolt or clip).
* C-clamp or rotor puller: To help remove the rotor if it's stuck.
* Hammer (rubber mallet preferred): May be needed to gently tap the rotor loose.
* Penetrating lubricant (like PB Blaster): To help loosen any rusted bolts.
* Wrench for caliper bracket bolts: This might be a different size than the caliper piston bolts, so check your vehicle beforehand.
* Gloves: To protect your hands.
Procedure:
1. Safety First: Park on a level surface, engage the parking brake, and chock the wheels. Use jack stands to securely lift the truck after raising it with the jack. Never work under a vehicle supported only by a jack.
2. Remove the Wheel: Remove the lug nuts and carefully remove the wheel.
3. Compress the Caliper Piston: Use a C-clamp or appropriate tool to compress the caliper piston. This will give you the clearance to remove the rotor. Important: You might need to open the bleeder valve slightly to release pressure from the brake system if using a C-clamp; otherwise, the piston may not compress far enough.
4. Remove the Caliper: Some models require removing the caliper entirely, while others allow for removal of the rotor with the caliper still attached (but it may be very difficult). If you need to remove the caliper, carefully detach the caliper bracket bolts. Some calipers hang on a bracket and can be simply moved out of the way with some play in the brake lines. Others require disconnecting the brake line. If you disconnect a brake line, be sure to have someone help you bleed the brakes afterwards. Support the caliper using wire or a bungee cord to keep it from hanging by the brake line.
5. Remove the Rotor: Inspect the rotor for any retaining bolts or clips. Some rotors are simply pressed onto the hub, while others use these. Remove any retaining hardware if present. If the rotor is stuck, use a rubber mallet to gently tap it from the back. A rotor puller may also be necessary. Tap around the circumference to loosen it evenly. Avoid damaging the wheel hub or rotor.
6. Inspect the Hub: Once the rotor is removed, inspect the wheel hub for any damage or corrosion. Clean and lightly lubricate the hub if needed.
7. Installation (Reverse Order): Installation is the reverse of the removal process. Remember to lubricate the hub and properly torque all bolts to the manufacturer's specifications (check your repair manual). After reinstalling the caliper, bleed the brakes if you disconnected the brake line.
Important Considerations:
* Brake Fluid: If you are working with the brake lines, be aware that brake fluid is corrosive and can damage paint.
* Torque Specifications: Always refer to your repair manual for the proper torque specifications for all bolts and nuts. Over-tightening can damage components.
* Rust and Corrosion: On older vehicles, rust and corrosion can make this process more difficult. Penetrating lubricant is your friend!
