Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Safety warning: Wear protective gear and ensure the vehicle is securely supported on jack stands.

2. Inspect and Replace Brake Pads

Remove the wheel using a socket set and torque wrench.
Remove the brake caliper bolts and carefully slide the caliper off the rotor.
Remove the old brake pads and inspect them for wear. Replace if worn unevenly.
Install new brake pads, ensuring they are seated correctly.
Reattach the caliper and tighten bolts to manufacturer torque specifications.

3. Inspect and Resurface or Replace Brake Rotors

Check rotor thickness with a micrometer; if below minimum specification, replace the rotor.
If rotors are within specification but warped, consider resurfacing them.
If resurfacing, follow manufacturer guidelines for runout and finish.
Reinstall the rotor (if resurfaced) and ensure it is torqued to specification.

4. Brake System Bleeding

Use a brake bleeder kit to remove air from the brake lines.
Start from the wheel furthest from the master cylinder (usually the right rear) and work towards the closest (left front).
Fill the master cylinder with the appropriate brake fluid as you bleed each line.
