Solution

1. Preparation

Gather tools: jack, jack stands, socket set, torque wrench, brake cleaner, and safety glasses.
Ensure the vehicle is on a flat surface and securely parked.
Disconnect the battery to avoid any electrical issues during the process.

2. Remove Wheel

Loosen wheel lug nuts slightly while the car is on the ground.
Use the jack to raise the vehicle and then secure it with jack stands.
Remove the lug nuts completely and take off the wheel to access the brake components.

3. Inspect Brake Components

Inspect brake pads for wear; replace if the thickness is below 3mm.
Check the brake rotors for scoring or warping; replace if necessary.
Clean the brake pad backing and caliper bracket with brake cleaner.
Inspect the caliper for any signs of leakage or improper alignment.

4. Replace Brake Pads (if necessary)

Remove the caliper by unscrewing the caliper bolts with a socket set.
Carefully slide the caliper off the rotor and support it without stretching the brake line.
Remove the old brake pads from the caliper bracket.
Install the new brake pads, making sure they are correctly oriented.
Reinstall the caliper over the new pads and torque the caliper bolts to manufacturer specifications.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle back to the ground and torque the lug nuts to manufacturer specifications.
Reconnect the battery.
Test the brakes by pressing the pedal several times to seat the pads.
