Solution

1. Preparation

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

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts using a socket set and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect: Check the thickness of the brake pads. If they are worn below 3mm, replacement is necessary.
Replace:
- Remove the caliper bolts with a socket set.
- Slide the caliper off the rotor and secure it without stressing the brake line.
- Remove old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are oriented correctly.

4. Inspect and Replace Brake Rotors (if necessary)

Inspect: Check the rotor for grooves or warping using a straightedge.
Replace:
- Remove the caliper bracket if necessary.
- Unscrew the rotor retaining screws (if equipped) using a screwdriver.
- Slide the rotor off the hub.
- Install the new rotor, ensuring it is seated properly.

5. Reassemble Components

Reattach the caliper bracket, torque the bolts to manufacturer's specifications.
Reinstall the caliper over the new pads, ensuring proper alignment.
Reattach the wheel, hand-tighten lug nuts, and lower the vehicle.

6. Final Checks

Pump the brake pedal to ensure proper pad seating.
Check brake fluid level and top off if necessary.
