Solution

1. Preparation

Gather tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Gather necessary tools: jack, jack stands, lug wrench, torque wrench, dial indicator, and brake cleaner.

2. Lift Vehicle

Use the jack to lift the front of the vehicle.
Secure the vehicle on jack stands to ensure safety.

3. Remove Wheel

Use a lug wrench to loosen and remove the lug nuts.
Remove the wheel and set it aside.

4. Inspect and Replace Brake Components

A. Brake Rotor Inspection

Measure rotor thickness using a micrometer.
If warped or below minimum thickness, replace rotors.

B. Brake Pad Inspection

Check pads for thickness; replace if they are worn down to the indicator.
Ensure pads are installed correctly and are not sticking.

5. Reassemble Components

Reinstall new or machined brake rotors.
Install new brake pads and ensure they are properly seated.
Reattach the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Torque Lug Nuts

Carefully lower the vehicle off jack stands.
Use a torque wrench to tighten the lug nuts to the manufacturer's specifications (typically 76 ft-lbs for Tacoma).

7. Final Checks

Inspect wheel bearings and suspension components for any additional issues.
If necessary, replace damaged or worn components.
