Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety gloves and goggles.

2. Lift the Vehicle

Use a floor jack to lift the front or rear of the vehicle as needed.
Secure it with jack stands.

3. Remove the Wheel

Use a lug wrench to loosen and remove the lug nuts.
Take off the wheel to access the brake components.

4. Inspect and Replace Brake Pads

Inspect Pads: Check the brake pads for signs of uneven wear.
Remove Caliper:
- Use a socket set to remove the caliper bolts.
- Hang the caliper using a bungee cord to avoid strain on the brake line.
Remove Old Pads:
- Slide the old brake pads out of the caliper bracket.
Install New Pads:
- Insert new brake pads into the caliper bracket, ensuring they are seated correctly.

5. Inspect and Replace Brake Rotors (if necessary)

Remove Rotor:
- If warped or damaged, remove the rotor by unscrewing the retaining screws and sliding it off the hub.
Install New Rotor:
- Clean the new rotor with brake cleaner.
- Slide the new rotor onto the hub and secure it with screws.

6. Reassemble the Braking System

Reattach the caliper over the new pads and rotor.
Tighten caliper bolts to manufacturer's torque specifications (typically around 20-30 lb-ft).

7. Reinstall the Wheel

Place the wheel back onto the hub.
Hand-tighten the lug nuts and lower the vehicle from the jack stands.
Torque the lug nuts to the specified value (usually about 76 lb-ft for most Toyota models).

8. Brake System Bleeding (if necessary)

If brake fluid was added or replaced, bleed the brake system to remove air bubbles.
Start with the brake furthest from the master cylinder and work your way closer (usually rear passenger to front driver).
