Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a flat surface and engage the parking brake.
Gather necessary tools: jack, jack stands, lug wrench, dial indicator, torque wrench, and brake cleaner.

2. Remove Wheel

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

3. Inspect and Replace Brake Rotors

Use the dial indicator to measure rotor runout. If it exceeds manufacturer specifications, replace the rotors.
If replacing, remove the caliper by unbolting it and disconnecting it from the bracket. Support it with a bungee cord to avoid stress on the brake line.
Remove the rotor by unscrewing any retaining screws and sliding it off the hub.
Install the new rotor and ensure it is seated correctly. Torque retaining screws to manufacturer specifications.

4. Inspect and Replace Brake Pads

Remove the brake pads from the caliper bracket. Measure the thickness and condition; replace if worn unevenly.
Clean the caliper bracket and apply brake grease to the backing of the new pads.
Install the new brake pads and ensure they fit snugly.

5. Reassemble and Torque

Reinstall the brake caliper over the new pads and rotor, ensuring it moves freely.
Replace the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to manufacturer specifications in a crisscross pattern.

6. Final Inspection

Inspect for any visible leaks around the brake system.
Test the brakes by pressing the pedal gently before driving.
