Safety First!
* Jack up the truck securely: Use jack stands under the frame, never rely solely on the jack. Chock the rear wheels.
* Wear safety glasses: Brake dust is irritating.
* Use gloves: To protect your hands.
* Dispose of old brake parts properly: Brake fluid and pads are hazardous waste.
Tools You'll Need:
* Jack and jack stands
* Wheel chocks
* Lug wrench
* Socket wrench set (metric)
* Brake caliper piston compression tool
* C-clamp (or equivalent for caliper piston compression)
* Pliers
* Wire brush
* Brake cleaner
* New brake pads
* New rotors (likely needed, unless inspection shows they're in good condition)
* Torque wrench
* Penetrating lubricant (like PB Blaster)
Steps:
1. Prepare the Vehicle: Park on a level surface, engage the parking brake, and chock the rear wheels. Loosen the lug nuts on the front wheels before jacking up the truck.
2. Remove the Wheels: Raise the truck using the jack and securely position jack stands. Remove the lug nuts and take off the wheels.
3. Remove the Caliper: Locate the caliper bolts holding the caliper to the knuckle. Spray penetrating lubricant on the bolts if needed and let it sit for a few minutes. Unscrew the bolts and carefully remove the caliper. It's often helpful to hang the caliper from the suspension using a wire or bungee cord to keep it out of the way and prevent damage to the brake hose.
4. Compress the Caliper Piston: Using a caliper piston compression tool or a C-clamp, carefully compress the caliper piston. This will make space for the new, thicker brake pads. Be careful not to damage the piston seal.
5. Remove the Old Brake Pads: Remove the old brake pads from the caliper bracket. Clean the caliper bracket with a wire brush and brake cleaner.
6. Inspect and Replace Rotors (if necessary): Inspect the brake rotors for scoring, grooves, or excessive wear. If they are damaged, they must be replaced. If replacing the rotors, you'll need to remove them using appropriate tools. (This typically involves removing additional bolts and potentially using a rotor puller).
7. Install New Rotors (if necessary): Clean the rotor mounting surface on the wheel hub. Install the new rotors, ensuring they are properly seated and tightened according to the manufacturer's specifications.
8. Install New Brake Pads: Insert the new brake pads into the caliper bracket.
9. Reinstall the Caliper: Carefully reinstall the caliper over the new brake pads, ensuring that it's properly aligned. Tighten the caliper bolts to the manufacturer's specified torque.
10. Reinstall the Wheel: Put the wheel back on, and tighten the lug nuts.
11. Lower the Vehicle: Carefully lower the truck from the jack stands.
12. Tighten Lug Nuts: Once the truck is on the ground, tighten the lug nuts in a star pattern to ensure even pressure.
13. Check Brake Fluid Level: Check the brake fluid level in the master cylinder reservoir and add fluid if necessary.
14. Pump the Brakes: Pump the brake pedal several times to ensure the brakes are working properly.
15. Test Drive: Take a short test drive to ensure the brakes are functioning correctly. If you feel anything unusual, stop immediately and have the brakes inspected by a qualified mechanic.
Important Considerations:
* Bleeding the Brakes: In some cases, bleeding the brakes might be necessary after replacing the pads and/or rotors. This removes air bubbles from the brake lines. If you're unsure how to bleed brakes, consult a professional.
* Torque Specifications: Always use a torque wrench and adhere to the manufacturer's specified torque values for all bolts and nuts. Incorrect tightening can lead to damage and safety hazards.
* Professional Assistance: If you're uncomfortable performing this task, it's best to take your truck to a qualified mechanic. Brake failure is a serious safety issue.
This is a general guide. Always refer to your vehicle's specific repair manual for detailed instructions and safety precautions. Improper brake repair can be dangerous. If you're unsure about any step, consult a qualified mechanic.
