Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, brake cleaner, safety goggles, gloves.
Safely park the vehicle on a flat surface, engage the parking brake, and disconnect the battery for safety.

2. Remove Wheel

Loosen the lug nuts with a lug wrench.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel to access the brake assembly.

3. Inspect Brake Components

Sub-steps:
- Visually inspect brake pads for wear; replace if less than 3mm thick.
- Check rotors for grooves or scoring; consider resurfacing or replacing if damaged.
- Examine the caliper for proper operation and any signs of leakage.
- Clean the brake pads and rotors with brake cleaner to remove any dust or debris.

4. Replace Brake Pads (if necessary)

Sub-steps:
- Remove the caliper bolts using a socket set and slide the caliper off the rotor.
- Remove old brake pads and install new pads, ensuring they are oriented correctly.
- Use a C-clamp to compress the caliper piston back into the caliper housing.
- Reinstall the caliper over the new pads and torque the caliper bolts to manufacturer specifications.

5. Reassemble and Test

Replace the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque lug nuts to the recommended value.
Reconnect the battery and perform a brake test at low speeds.
