Solution

1. Preparation

Gather tools: jack, jack stands, wheel chocks, lug wrench, torque wrench, caliper gauge, runout gauge, OBD-II scanner.
Ensure the vehicle is on a flat surface, and the parking brake is engaged.
Disconnect the battery (if applicable) for safety.

2. Remove Wheel

Loosen the lug nuts with the lug wrench (do not fully remove yet).
Use the jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

Check brake pads:
- Measure the thickness; replace if below manufacturer specifications (usually 3 mm).
Inspect rotors:
- Use a runout gauge to check for warping; replace if warping exceeds manufacturer limits (typically 0.002 inches).
Check calipers:
- Ensure calipers move freely and are not sticking; lubricate slide pins if necessary.

4. Replace Brake Pads and Rotors (if needed)

Brake Pads Replacement:
- Remove the caliper bolts using a socket.
- Slide the caliper off and support it with a hanger (do not let it hang by the brake line).
- Remove old pads and install new ones, ensuring correct orientation.
- Reinstall caliper and torque bolts to manufacturer specifications.
Brake Rotor Replacement:
- Remove the rotor by unscrewing any retaining screws (if present) and sliding it off the hub.
- Clean the hub surface to remove any rust or debris.
- Install the new rotor and secure it if necessary.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to manufacturer specifications (usually 76-80 ft-lbs).
Reconnect the battery if disconnected.
Pump the brake pedal a few times to ensure proper brake function.
