Solution

1. Preparation

Gather tools and ensure the vehicle is parked on a level surface.
Safety: Engage the parking brake and wear safety goggles.
Tools Required: Jack, jack stands, lug wrench, torque wrench, caliper tool, runout gauge.

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the brake caliper by unscrewing the caliper bolts.
Slide the caliper off the rotor and support it with a bungee cord (do not hang by the brake line).
Remove old brake pads from the caliper bracket.
Inspect the brake pads for uneven wear; replace if necessary.
Install new brake pads, ensuring they are correctly aligned.

4. Check and Resurface or Replace Rotors

Use a runout gauge to measure the rotor’s runout; if it exceeds specifications, resurface or replace the rotor.
If replacing, remove the rotor by unscrewing the retaining screws.
Install new or resurfaced rotors and torque to manufacturer specifications.

5. Reassemble Braking Components

Reinstall the brake caliper over new pads and rotor.
Tighten caliper bolts to the specified torque.
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Checks

Lower the vehicle to the ground and fully tighten the lug nuts to the proper torque specification.
Remove any tools from the workspace and ensure everything is secure.
