Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery for safety.

2. Remove the Wheel

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

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket set.
Carefully slide off the brake caliper and suspend it with a wire or bungee cord to avoid straining the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the brake pads for wear; if the material is below 3mm, replace with new pads.
Apply anti-squeal lubricant to the back of the new brake pads and install them into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Check the brake rotor for scoring, rust, or warping.
If damaged, remove the caliper bracket bolts and slide off the old rotor.
Clean the hub surface before installing the new rotor.
Install the new rotor and torque the caliper bracket bolts to the manufacturer's specifications.

5. Reassemble and Test

Reattach the brake caliper and torque the caliper bolts.
Reinstall the wheel and lug nuts, tightening them in a star pattern.
Lower the vehicle and reconnect the battery.
Pump the brake pedal several times to seat the brake pads.
