Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Use wheel chocks to prevent the vehicle from rolling.
Disconnect the battery to ensure safety while working.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts with a socket wrench and take off the wheel.

3. Replace Brake Pads

Remove caliper: Use a socket wrench to remove the caliper mounting bolts and slide the caliper off the rotor.
Remove old brake pads: Slide the old brake pads out of the caliper bracket.
Install new brake pads: Insert new brake pads into the caliper bracket, ensuring they are properly oriented.
Reinstall caliper: Position the caliper over the new pads and secure it with mounting bolts. Torque bolts to manufacturer specifications (typically around 20-30 lb-ft for most models).

4. Inspect and Replace Brake Rotors (if necessary)

Check rotor condition: Use a caliper gauge to measure thickness and check for warping or scoring.
Replace rotors: If worn, remove the rotor by unscrewing the retaining screws (if applicable) and remove the rotor from the hub.
Install new rotors: Place the new rotor onto the hub and secure with retaining screws, if present.

5. Final Assembly

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to manufacturer specifications (typically around 76-90 lb-ft).
Reconnect the battery.
