Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, brake cleaner, safety glasses, gloves.
Safety Warnings: Ensure the vehicle is on a level surface and secured with jack stands. Wear safety glasses and gloves.

2. Remove Wheel

Loosen the lug nuts slightly with the lug wrench.
Raise 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

Inspect for Wear: Check the thickness of the brake pads. Replace if below 3mm.
Remove Caliper: Unbolt the caliper using a socket set and hang it securely using a bungee cord.
Remove Old Pads: Slide the old pads out of the caliper bracket.
Install New Pads: Apply brake grease to the backing of the new pads, then slide them into the bracket.
Reattach Caliper: Position the caliper back over the new pads and torque bolts to manufacturer specifications.

4. Inspect and Resurface/Replace Rotors

Check Rotor Condition: Measure rotor thickness and check for scoring.
Resurface or Replace: If rotors are within spec, resurface them. If not, replace with new rotors.
Reinstall Rotors: If replaced, slide the new rotor onto the hub.

5. Reassemble Components

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle, then torque the lug nuts to manufacturer specifications in a star pattern.

6. Final Checks

Pump the brake pedal to seat the pads against the rotors.
Check brake fluid level and top off if necessary.
