Solution

1. Preparation

Gather tools and materials before starting the repair.
Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, brake cleaner, C-clamp, and possibly a multimeter.
Safety Warnings: Ensure the vehicle is on a flat surface and secure with wheel chocks before lifting.

2. Remove Wheel

Loosen lug nuts slightly while the car is still on the ground.
Raise the vehicle with a jack and secure it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Clean Brake Components

Remove the brake caliper by unscrewing the caliper bolts (consult vehicle manual for torque specifications).
Carefully hang the caliper using a wire to avoid stressing the brake line.
Remove the brake pads and inspect for wear patterns.
Clean the caliper bracket and rotor surface with brake cleaner.

4. Replace Brake Pads (if necessary)

If pads are unevenly worn, replace them with new OEM or quality aftermarket pads.
Ensure pads are installed in the correct orientation and seated properly in the caliper bracket.

5. Reassemble Components

Reinstall the brake caliper and torque bolts to manufacturer specifications.
Reinstall the wheel and hand-tighten lug nuts.
Lower the vehicle and torque the lug nuts in a star pattern to the specified torque.

6. Test Brake System

Pump the brake pedal to seat the pads against the rotors.
Check for any abnormal noises or function during a low-speed test drive.
