Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and securely lift it using a jack.
Use wheel chocks to prevent movement.

2. Remove Wheel

Use a socket set to remove the lug nuts and take off the wheel.
Place the wheel aside in a safe location.

3. Remove Brake Caliper

Use a socket to remove the caliper mounting bolts.
Carefully slide the caliper off the brake rotor; support it using a bungee cord to avoid straining the brake line.

4. Inspect and Replace Brake Pads

Remove old brake pads from the caliper bracket.
Inspect the brake rotor for wear; resurface or replace if necessary.
Install new brake pads in the caliper bracket, ensuring proper orientation.

5. Reassemble Components

Slide the brake caliper back over the new pads and rotor.
Reinstall the caliper mounting bolts; torque to manufacturer specifications (typically around 25-35 Nm).
Reinstall the wheel and torque the lug nuts to the manufacturer's specification (usually 120 Nm).

6. Final Checks

Lower the vehicle and pump the brake pedal several times to seat the new pads.
Check brake fluid level and top off if necessary.
