Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety glasses and gloves.

2. Remove Wheel

Sub-steps:
1. Loosen wheel lug nuts with a socket or impact wrench.
2. Lift the vehicle using a jack and secure it with jack stands.
3. Remove the wheel completely.

3. Inspect and Replace Components

Inspect Brake Pads:
- Check both inner and outer pads for wear. Replace if thickness is below 3mm.
Inspect Calipers:
- Remove caliper bolts with a socket.
- Slide the caliper off the rotor. Check for sticking or uneven movement. Clean and lubricate the caliper slides if necessary, or replace if damaged.
Inspect Rotors:
- Measure rotor thickness with a micrometer. Replace if below specification or if warped.
Replace Pads and Rotors:
- Install new pads and/or rotors as needed. Ensure the pads are properly oriented and that all hardware is reinstalled.

4. Reassemble and Test

Reassemble Components:
1. Reinstall the caliper over the new pads.
2. Torque caliper bolts to manufacturer specifications (usually around 25-30 Nm).
3. Reinstall the wheel and hand-tighten the lug nuts.
Lower Vehicle:
- Carefully lower the vehicle from the jack stands and fully tighten the lug nuts in a star pattern to the specified torque (typically 110 Nm).

5. Brake System Bleeding (If Required)

If brake fluid was lost during the process, bleed the brake system using a brake bleeder kit to ensure no air is in the lines.
