Solution

1. Preparation

Tools Required: Brake cleaner, jack and jack stands, lug wrench, torque wrench, socket set.
Safety Warnings: Always engage the parking brake and ensure the vehicle is on a flat surface. Wear safety glasses and gloves.

2. Remove Wheel

Loosen the lug nuts with a lug wrench while the vehicle is on the ground.
Raise the vehicle with a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel to access the brake assembly.

3. Inspect and Replace Brake Pads

Remove the caliper by unscrewing the caliper bolts with a socket set.
Carefully slide the caliper off the brake pads without disconnecting the brake line.
Inspect the brake pads for wear; replace if the friction material is less than 3mm thick.
If replacing, install new brake pads by sliding them into the caliper bracket.
Reinstall the caliper over the new pads and secure it with the caliper bolts. Torque the bolts to the manufacturer's specifications (usually around 20-30 ft-lbs).

4. Inspect and Resurface/Replace Rotors

Check the brake rotors for any visible damage or warping.
If the rotor thickness is below the minimum specification or shows signs of scoring, replace it. Otherwise, resurface the rotor if it is not damaged.
Clean the rotor surface with brake cleaner before reinstallation.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and tighten the lug nuts in a crisscross pattern to the specified torque (typically 100-120 ft-lbs).
Pump the brake pedal a few times to seat the brake pads against the rotor.
