Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake assembly.

3. Inspect Brake Pads and Rotors

Examine the brake pads for uneven wear; replace if necessary.
Measure rotor thickness with a caliper; replace if below manufacturer specifications.
Check for signs of warping by visually inspecting the rotor surface.

4. Replace Brake Pads and/or Rotors (if needed)

If replacing pads:
- Remove the caliper bolts using a socket set.
- Slide the caliper off the rotor and support it without stressing the brake line.
- Remove the old brake pads and install new ones, ensuring proper orientation.
If replacing rotors:
- Remove the old rotor by unbolting it from the hub.
- Install the new rotor and torque bolts to the manufacturer's specifications.

5. Reassemble and Test

Reattach the caliper over the new pads and torque caliper bolts to specification.
Reinstall the wheel and torque the lug nuts in a crisscross pattern.
Lower the vehicle and test the brake system by pressing the pedal to ensure it feels firm.
