Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a flat surface and the engine is off.
Engage the parking brake and use wheel chocks.

2. Remove Wheel

Loosen lug nuts slightly before lifting the vehicle.
Use a jack to raise the vehicle and secure it with jack stands.
Fully remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Pads: Check both inner and outer pads for wear patterns. Note which side is more worn.
Remove Caliper: Use a socket set to remove the caliper mounting bolts. Support the caliper using a bungee cord or rope to avoid stress on the brake line.
Remove Old Pads: Slide the brake pads out of the caliper bracket.
Install New Pads: Align new pads in the caliper bracket, ensuring they are seated correctly.

4. Inspect and Replace Components as Needed

Check Rotors: If rotors are worn or warped, replace or resurface them.
Inspect Calipers: If calipers are sticking, clean or replace caliper hardware and pistons as necessary.
Brake Fluid: Check and top up brake fluid as needed, using the manufacturer-recommended fluid.

5. Reassemble and Test

Reattach Caliper: Reinstall the caliper over the new brake pads and torque the mounting bolts to manufacturer specifications.
Reinstall Wheel: Place the wheel back on, hand-tighten the lug nuts, lower the vehicle, and then torque the lug nuts to specifications.
Test Brakes: Before driving, pump the brake pedal to seat the pads and ensure proper function.
