Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely lifted with jack stands.
Remove the wheel to access the rear brake components.

2. Inspect and Replace Brake Pads

Remove the brake caliper using a socket set (typically 14mm or 17mm).
Carefully suspend the caliper using a bungee cord or hook to avoid strain on the brake line.
Remove the old brake pads by sliding them out of the caliper bracket.
Inspect the new brake pads for proper fit and any damage.
Apply a thin layer of brake grease to the backing plate of the new pads to prevent noise.
Install the new brake pads into the caliper bracket.

3. Inspect and Resurface/Replace Rotors

Check the thickness of the rotors using a micrometer or caliper; replace if below the minimum specification (usually 24mm for most Toyota rotors).
If rotors are within spec but scored, consider resurfacing them; if severely damaged, replace them.
Clean the rotor surface with brake cleaner to remove any debris or contaminants.
Install the rotor back onto the hub, ensuring it is seated properly.

4. Reassemble Brake Components

Reinstall the brake caliper over the new brake pads.
Torque the caliper bolts to the manufacturer's specifications (usually around 25-30 ft-lbs).
Reinstall the wheel and torque the lug nuts to specifications (usually around 76 ft-lbs).
Repeat the process on the other rear wheel if necessary.

5. Final Checks

Pump the brake pedal several times to ensure proper pad seating.
Check brake fluid level and top off if necessary.
Clean up the work area and ensure all tools are accounted for.
