Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and securely raise it using a jack and jack stands.
Disconnect the battery for safety.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts.
Lift the vehicle using a jack and securely place it on jack stands.
Remove the lug nuts and take off the wheel to access the brake assembly.

3. Inspect and Replace Brake Pads

Inspect: Check the thickness of the brake pads. If they are worn down to 3 mm or less, they need replacement.
Remove Pads: Unscrew and remove the caliper bolts using a socket set. Carefully lift the caliper off the rotor and support it with a bungee cord or similar.
Replace Pads: Remove the old brake pads and install new ones. Ensure they are aligned correctly and seated properly.

4. Check and Replace Brake Rotors (if necessary)

Inspect Rotors: Check for any scoring or uneven wear. If they are below the minimum thickness or warped, they need to be replaced.
Remove Rotors: Remove the caliper bracket if necessary to access the rotor. Unscrew and slide off the rotor.
Install New Rotors: Place the new rotor onto the hub, ensuring it is properly aligned. Reattach the caliper bracket.

5. Reassemble Brake Components

Reattach the caliper over the new pads and rotor. Ensure all bolts are tightened to the manufacturer's torque specifications (typically around 25-35 Nm).
Reinstall the wheel and lug nuts, tightening them in a crisscross pattern to ensure even pressure.

6. Final Checks

Reconnect the battery.
Pump the brake pedal a few times to ensure proper brake pad seating.
Check brake fluid level and top off if necessary.
