Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, brake cleaner, torque wrench, safety goggles, gloves.
Secure the vehicle by parking on a level surface and engaging the parking brake.
Wear safety goggles and gloves to protect against debris and chemicals.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Components

Brake Pads:
- Remove the caliper bolts using the appropriate socket.
- Slide the caliper off the rotor and support it without stretching the brake line.
- Remove the old brake pads from the caliper bracket.
- Inspect the new pads for compatibility and install them into the bracket.
Brake Rotors:
- Check the rotor surface for damage or scoring.
- If damaged, remove the rotor by unscrewing the retaining screws (if equipped) and pulling it off the hub.
- Install a new rotor ensuring it is clean and free of oils.
Brake Calipers:
- Inspect the caliper for any signs of sticking or damage.
- If necessary, replace the caliper by disconnecting the brake line and mounting bolts, and bleeding the brake system upon installation of the new caliper.

4. Reassemble and Test

Reinstall the caliper over the new brake pads and torque the caliper bolts to manufacturer specifications (typically around 25-35 lb-ft).
Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the recommended specification (usually 76-83 lb-ft for a RAV4).

5. Clean and Inspect

Clean the brake assembly with brake cleaner to remove any dust or debris.
Ensure everything is secure and properly installed before testing.
