Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the negative battery terminal for safety.

2. Remove the Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts using a socket and ratchet.
Take off the wheel to access the brake components.

3. Inspect and Replace Brake Components

A. Brake Rotor Inspection

Check if the rotors are warped using a dial indicator. If warping exceeds manufacturer specifications, replace the rotors.
If rotors are in good condition, clean them with brake cleaner.

B. Brake Pad Inspection

Remove the brake caliper by unbolting it from the bracket.
Inspect the brake pads for thickness; replace if they are worn below 3mm.
Replace pads by sliding new ones into the caliper bracket.

C. Reassemble Brake System

Reinstall the brake caliper over the new pads and torque the bolts to manufacturer specifications.
Repeat the inspection for the other wheel if necessary.

4. Reinstall the Wheel

Place the wheel back onto the hub.
Hand-tighten the lug nuts and then lower the vehicle.
Torque the lug nuts to the manufacturer's specification using a torque wrench.

5. Final Checks

Reconnect the negative battery terminal.
Perform a brake fluid check and top off if necessary.
Test the brakes in a safe area to ensure proper operation.
