Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, brake cleaner, safety goggles, gloves.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety goggles and gloves for protection.

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Use the jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

Brake Pads:
- Remove the brake caliper by unbolting it from the bracket.
- Inspect the brake pads for thickness; replace if worn below 3mm.
- If pads are worn unevenly, check caliper slide pins for sticking.
Brake Rotors:
- Inspect the brake rotor surface for grooves or scoring.
- If damaged, replace the rotors. If slightly worn, consider resurfacing.
Calipers:
- Check for fluid leaks around the caliper seals.
- Ensure the caliper moves freely on its slides.

4. Replace Components (if necessary)

If brake pads are worn:
- Remove old pads and install new ones, ensuring they are properly seated.
If rotors are damaged:
- Unbolt old rotor and replace with a new rotor, securing it to the hub.

5. Reassemble and Torque

Reinstall the brake caliper over the new pads and rotor.
Torque caliper bolts to manufacturer specifications (usually around 25-30 ft-lbs).
Replace the wheel and hand-tighten the lug nuts, then lower the vehicle back to the ground.

6. Final Checks

Torque the lug nuts to the specified value (typically 76-82 ft-lbs for Corolla).
Pump the brake pedal a few times to ensure proper seating of the pads and caliper.
