Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical issues.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts with a socket and ratchet.
Take off the wheel to access the braking components.

3. Inspect Brake Components

Visually inspect the brake pads, calipers, and rotors.
Measure brake pad thickness with a caliper; replace if below manufacturer specifications.
Check for caliper movement; if sticking, consider replacing or servicing the caliper.

4. Replace Brake Pads (if necessary)

Remove the caliper bolts using a socket and ratchet.
Carefully slide the caliper off the rotor and support it with a bungee cord to avoid strain on the brake line.
Remove old brake pads from the caliper bracket.
Apply brake grease to the back of the new pads and install them in the caliper bracket.

5. Reassemble

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

6. Finish Up

Reconnect the negative battery terminal.
Pump the brake pedal a few times to seat the brake pads properly.
Check brake fluid level and top off if necessary.
