Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent any electrical issues.

2. Remove Wheel

Use a jack to lift the vehicle and secure it on jack stands.
Remove the lug nuts using a socket set and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads: Check for excessive wear; if they are worn down to the metal, they need replacement.
Remove Brake Caliper: Use a socket set to remove the caliper mounting bolts. Hang the caliper using a bungee cord to avoid strain on the brake line.
Remove Old Pads: Slide out the old brake pads from the caliper bracket.
Install New Pads: Insert new brake pads into the caliper bracket, ensuring they are oriented correctly.

4. Inspect and Replace Rotors

Check Rotors: Inspect for grooves or warping; if damaged, replace them.
Remove Brake Rotor: If necessary, remove the rotor by unscrewing any retaining screws or bolts.
Install New Rotor: Place the new rotor on the hub and secure it.

5. Reassemble

Reattach the brake caliper over the new pads and rotor, tightening the caliper bolts to the manufacturer's torque specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value.

6. Final Checks

Reconnect the battery.
Pump the brake pedal to ensure proper pad seating before driving.
