Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, brake cleaner, anti-squeal lubricant.
Safety Warnings: Ensure the vehicle is on a flat surface and use wheel chocks to prevent rolling.

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and securely place it on jack stands.
Remove the lug nuts completely and take off the rear wheel.

3. Inspect and Remove Brake Components

Remove the caliper bolts using a socket set.
Slide the caliper off the rotor and support it using a bungee cord or rope to avoid stress on the brake line.
Remove the brake pads from the caliper bracket.

4. Clean and Prepare Components

Clean the brake rotor surface using brake cleaner to remove dust and debris.
Inspect the rotor for any signs of damage; if warped or excessively worn, replace the rotor.
Apply anti-squeal lubricant to the back of the new brake pads.

5. Install New Brake Pads and Reassemble

Place the new brake pads into the caliper bracket.
Reattach the caliper over the new pads.
Torque the caliper bolts to the manufacturer's specifications (usually around 30-40 Nm).
Reinstall the wheel and torque lug nuts to the manufacturer's specifications.

6. Final Check

Lower the vehicle off the jack stands and remove wheel chocks.
Pump the brake pedal a few times to ensure proper pad seating.
