Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the parking brake engaged.
Wear safety glasses and gloves for protection.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle based on the affected brake system.
Secure the vehicle with jack stands for safety.

3. Remove Wheel

Use a lug wrench to loosen and remove the lug nuts.
Take off the wheel to access the brake components.

4. Inspect and Replace Brake Pads

Inspection:
- Remove the caliper bolts using a socket set.
- Slide the caliper off the rotor and support it without stressing the brake line.
- Inspect the brake pads for thickness; replace if less than 3mm.
Replacement:
- Remove old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are properly seated.
- Apply brake grease to the back of the pads to reduce noise.

5. Inspect and Replace Brake Rotors (if necessary)

Check the rotor surface for grooves or warping.
If damaged, remove the rotor by unscrewing the retaining bolts.
Install new rotors, ensuring they are clean and free of oil.
Torque the rotor bolts to the manufacturer's specification (usually around 90 lb-ft).

6. Reassemble Brake Components

Reinstall the caliper over the new brake pads and rotor.
Secure caliper bolts to the manufacturer's torque specification (typically 25-35 lb-ft).
Reattach the wheel and torque lug nuts to the manufacturer's specification (usually 76 lb-ft).

7. Final Checks

Lower the vehicle back to the ground.
Pump the brake pedal several times to ensure proper brake pad seating.
