Solution

1. Preparation

Tools Required: Jack, jack stands, wheel chocks, socket set, torque wrench, brake cleaner, gloves, safety glasses.
Safety Warnings: Ensure the vehicle is on a level surface and securely supported by jack stands before working on it. Wear safety glasses and gloves.

2. Remove Wheel

Loosen the lug nuts on the wheel using a socket wrench.
Lift the vehicle with a jack and secure it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Components

Inspect Brake Pads:
- Check the thickness of the brake pads. If worn down to 3mm or less, replace them.
- Remove the caliper bolts using a socket wrench and slide the caliper off the rotor.
- Use a brake pad spreader tool to compress the caliper piston if necessary.
- Remove old brake pads and install new ones, ensuring they are properly seated.
Inspect and Replace Rotors (if needed):
- Check the rotors for grooves or scoring. If they are damaged beyond resurfacing, replace them.
- To remove the rotor, take off any retaining screws and slide the rotor off the hub.
- Clean the hub surface with brake cleaner before installing new rotors.
- Install new rotors and secure them with retaining screws.
Reassemble Caliper:
- Reinstall the caliper over the new brake pads.
- Torque the caliper bolts to the manufacturer’s specifications (usually around 25-30 ft-lbs for Tacoma).

4. Reinstall Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle off the jack stands.
Torque the lug nuts to the proper specifications (typically 80-100 ft-lbs).

5. Final Checks

Recheck brake fluid levels in the master cylinder and add fluid if necessary.
Pump the brake pedal a few times to ensure proper pedal feel and position.
