Solution

1. Preparation

Gather tools: jack stands, lug wrench, torque wrench, brake pad spreader, caliper tool, and a runout gauge.
Ensure the vehicle is on a flat surface and securely supported with jack stands.
Disconnect the battery if working on electronic components.

2. Inspect and Replace Brake Pads

Remove the wheel using the lug wrench.
Inspect brake pads for wear; replace if they are worn down.
- Tools Required: Brake pad spreader.
- Safety Warnings: Wear gloves and safety glasses to protect from dust and debris.
If replacing, install new brake pads following manufacturer specifications.

3. Check and Resurface/Replace Rotors

Use a runout gauge to measure rotor flatness. If warped beyond specifications, replace or resurface them.
- Tools Required: Runout gauge, rotor resurfacing tool (if applicable).
If replacing rotors, remove the caliper and rotor from the hub.
Install new rotors, ensuring they are properly seated.

4. Inspect Brake Calipers

Check brake calipers for proper operation. Look for signs of sticking or leaks.
If necessary, rebuild or replace the caliper.
- Tools Required: Caliper tool, brake cleaner.

5. Reassemble and Torque Components

Reinstall the wheel and lug nuts.
Torque lug nuts to manufacturer specifications using a torque wrench.
