Here's a general guide. Consult your vehicle's repair manual for precise torque specifications and any model-specific nuances. This is a general procedure and variations may exist.
Tools You'll Need:
* Jack and jack stands: Absolutely essential for safety.
* Wheel chocks: To prevent the vehicle from rolling.
* Lug wrench: To remove the wheel nuts.
* Sockets and wrenches: Various sizes depending on your vehicle's specifications (consult your manual). You'll likely need sockets for caliper bolts, rotor retaining bolts (if any), and possibly lug nuts.
* C-clamp or caliper compression tool: To compress the caliper piston.
* Wire or a bungee cord: To hold the caliper out of the way.
* Torque wrench: Crucial for properly tightening bolts to prevent damage.
* Penetrating oil (PB Blaster or similar): Helps loosen rusted or seized bolts.
* Clean rags or shop towels: To clean up brake dust and fluids.
* Safety glasses and gloves: Protect yourself from flying debris and brake dust.
* New front brake rotors: Make sure you get the correct ones for your vehicle.
* Optional: Wire brush: To clean the hub mating surface.
Procedure:
1. Safety First: Park the vehicle on a level surface, engage the parking brake, and chock the rear wheels. Use the jack to lift the front of the vehicle, then securely place it on jack stands.
2. Remove the Wheel: Loosen the lug nuts slightly before jacking up the vehicle. Remove the wheel and set it aside.
3. Remove the Caliper:
* Use a socket wrench to remove the caliper mounting bolts. Penetrating oil may be necessary if they're stuck.
* Carefully remove the caliper. You might need to gently pry it away from the rotor. Support the caliper's weight; do not let it hang by the brake hose. You can use a wire or bungee cord to hang it from something nearby.
4. Compress the Caliper Piston: Using a C-clamp or caliper compression tool, slowly and evenly compress the caliper piston. This creates space to accommodate the new, thicker rotor. Be careful not to damage the piston seal.
5. Remove the Rotor:
* Some Trackers have a retaining bolt or screw holding the rotor to the hub. If present, remove it.
* Usually, the rotor simply slides off the hub. If it's stuck, gently tap it from the back with a rubber mallet or use a rotor puller (if necessary). Avoid damaging the hub's mating surface.
6. Clean the Hub: Use a wire brush (if needed) to clean any rust, dirt, or debris from the wheel hub mating surface. This ensures proper contact between the hub and the new rotor.
7. Install the New Rotor: Slide the new rotor onto the hub. Make sure it's seated properly and flush against the hub. If there's a retaining bolt, reinstall it.
8. Reinstall the Caliper: Carefully reinstall the caliper over the new rotor, ensuring it aligns correctly with the caliper mounting bracket. Tighten the caliper mounting bolts to the manufacturer's specified torque.
9. Reinstall the Wheel: Put the wheel back on and tighten the lug nuts snugly but not completely tight yet.
10. Lower the Vehicle: Lower the vehicle to the ground.
11. Torque Lug Nuts: Tighten the lug nuts to the manufacturer's specified torque using a torque wrench.
12. Final Check: Double-check that all bolts are tightened properly. Pump the brake pedal several times to ensure the brakes engage properly. Test drive the vehicle carefully to verify everything functions correctly.
Important Considerations:
* Brake fluid: If you're working on the braking system, be prepared for the possibility of brake fluid spillage. Brake fluid is corrosive, so clean up any spills immediately.
* Brake pad thickness: Inspect your brake pads while the caliper is off. Replace them if they are worn down below the minimum thickness.
* Professional help: If you are not comfortable performing this repair, take your vehicle to a qualified mechanic. Brake systems are critical for safety.
This is a general guide. Always refer to your vehicle's repair manual for the most accurate and detailed instructions. Improper installation of brake components can lead to dangerous situations. If you are unsure about any step, seek professional assistance.
