Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the negative battery terminal to prevent any electrical issues.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Remove the caliper bolts with a socket wrench.
Carefully slide the caliper off the rotor. Support it with a bungee cord or similar method to avoid strain on the brake line.
Inspect the brake pads for wear. If they are worn down to the indicator, replace them.
To install new pads, compress the caliper piston using a brake caliper tool.
Place new brake pads into the caliper bracket and reattach the caliper.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotor surface for scoring or warping. If damaged, remove the rotor by unbolting it from the hub.
Clean the hub surface with brake cleaner.
Install new rotors by reversing the removal process and torquing the bolts to manufacturer specifications.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts to the proper torque specification.
Reconnect the negative battery terminal.
Test the brakes by pressing the pedal several times to ensure proper engagement.
