Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Use wheel chocks for additional safety.

2. Brake Inspection and Replacement

Remove the Wheel
- Use a lug wrench to loosen the lug nuts.
- Lift the vehicle with a jack and secure it on jack stands.
- Remove the lug nuts and take off the wheel.
Inspect Brake Components
- Visually check brake pads for thickness; replace if less than 3mm.
- Inspect the brake rotors for scoring or warping; replace if necessary.
Replace Brake Pads and Rotors
- If pads need replacement, remove caliper bolts using a socket set, then lift the caliper away from the rotor.
- Replace the brake pads and reassemble caliper.
- If rotors are replaced, remove rotor screws using a screwdriver, install new rotors, and secure them.
Reassemble
- Reinstall the wheel and hand-tighten the lug nuts.
- Lower the vehicle, then torque the lug nuts to the manufacturer's specifications (typically 75 ft-lbs for Toyota).

3. Wheel Bearing Inspection and Replacement

Remove the Brake Assembly
- Repeat the wheel removal process.
- Remove the brake caliper and rotor to access the wheel bearing.
Check Bearing for Wear
- Spin the hub and listen for grinding noises.
- If noise is present, the bearing must be replaced.
Replace Wheel Bearing
- Use a bearing puller to remove the old bearing.
- Press in the new bearing using a bearing press or suitable tool.
- Reassemble the brake components and wheel.
