Solution

1. Preparation

Gather all necessary tools and equipment.
Park the vehicle on a flat surface and engage the parking brake.
Lift the vehicle using a jack and secure it with jack stands for safety.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check the thickness of each pad and note any uneven wear.
Remove Brake Caliper:
- Use a socket set to remove the bolts securing the brake caliper.
- Carefully slide the caliper off the rotor and suspend it with a bungee cord to avoid stress on the brake line.
Remove Old Brake Pads:
- Slide the old brake pads out of the caliper bracket.
Install New Brake Pads:
- Place new brake pads into the caliper bracket. Ensure they are secured correctly.
Reattach Brake Caliper:
- Slide the caliper back over the new pads and torque the caliper bolts to the manufacturer's specifications (typically around 20-30 lb-ft).

4. Inspect and Replace Brake Rotors (if needed)

Remove Brake Rotor:
- If the rotor shows signs of wear or warping, remove it by unscrewing the retaining screws (if applicable) and gently tapping it with a hammer.
Install New Brake Rotor:
- Place the new rotor onto the hub, ensuring it’s properly seated.

5. Reassemble and Test

Replace the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (usually 80-100 lb-ft).
Pump the brake pedal a few times to seat the pads against the rotor before test driving.
