Here's a general guide. Specific steps may vary slightly depending on your exact model and any modifications. Always consult a repair manual specific to your year and model for precise instructions and torque specifications.
Tools You'll Need:
* Jack and jack stands (Crucial for safety)
* Lug wrench
* Wheel chocks
* Socket wrench set (Metric)
* Ratchet
* Brake caliper piston compressor tool (C-clamp can be used as a makeshift but a dedicated tool is recommended)
* Wire brush or brake cleaner
* New brake pads (ensure you get the correct ones for your vehicle)
* Torque wrench (highly recommended)
* Penetrating oil (like PB Blaster)
* Gloves and safety glasses
Procedure:
1. Safety First: Park on a level surface, engage the parking brake firmly, and chock the rear wheels. Raise the front of the truck using the jack and securely support it on jack stands. Never work under a vehicle supported only by a jack.
2. Remove the Wheel: Remove the lug nuts and take off the wheel.
3. Expose the Caliper: You'll see the brake caliper clamping onto the rotor.
4. Remove the Caliper: There are typically two bolts holding the caliper to the caliper bracket. Use your socket wrench to carefully remove these bolts. Once loose, carefully support the caliper—you can hang it from the suspension using a piece of wire or hang it from a bungee cord to avoid stressing the brake line.
5. Compress the Caliper Piston: This is critical. The new brake pads will be thicker than the old ones. Use the caliper piston compressor tool to push the piston back into the caliper. This allows the new, thicker pads to fit. Turn the piston slowly and evenly to avoid damaging the seals. If using a C-clamp, be extremely careful not to damage the piston or caliper.
6. Remove Old Brake Pads: The old brake pads should now be easily removable. They are typically held in place by a pin or clip. Remove any retaining clips and take out the old pads.
7. Clean: Use a wire brush to clean any rust or debris from the caliper bracket and the sliding pins (if applicable). Clean the caliper and piston with brake cleaner.
8. Install New Brake Pads: Insert the new brake pads into the caliper bracket, ensuring they are seated correctly.
9. Reinstall Caliper: Carefully reinstall the caliper onto the bracket, making sure the sliding pins (if present) are lubricated with a high-temperature caliper grease. Tighten the caliper bolts to the manufacturer's specified torque.
10. Reinstall the Wheel: Put the wheel back on and tighten the lug nuts. Lower the truck from the jack stands.
11. Torque Lug Nuts: Use a torque wrench to tighten the lug nuts to the manufacturer's specified torque.
12. Pump the Brakes: Before driving, pump the brake pedal several times to ensure the pads are properly seated.
Important Considerations:
* Brake Rotor Inspection: Inspect the brake rotors for wear and tear. If they are excessively worn, grooved, or warped, they may need to be replaced or resurfaced.
* Brake Fluid: If you're doing a complete brake job, you may need to bleed the brakes afterwards to remove air bubbles in the brake lines.
* Caliper Slides: Ensure the caliper slides smoothly. If they are stiff or seized, they may need to be cleaned and lubricated.
This is a general guide. Consult a repair manual specific to your vehicle for detailed instructions, torque specifications, and safety precautions. If you're not comfortable performing this repair yourself, it's always best to take your vehicle to a qualified mechanic.
