Solution

1. Preparation

Required Tools: Jack and jack stands, lug wrench, socket set, torque wrench, brake cleaner, wire brush, and a C-clamp.
Safety Warning: Ensure the vehicle is on a flat surface and properly secured with jack stands before working.

2. Remove Wheel

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

3. Inspect and Service Brake Components

Inspect Brake Pads:
- Remove the caliper bolts using the socket set and slide the caliper off the rotor.
- Check for uneven wear on the brake pads. Replace any severely worn pads.
Check Brake Caliper:
- Ensure the caliper slides freely and is not sticking. If it is, clean the caliper slides and apply lubrication if necessary.
- If the caliper is damaged, replace it.
Inspect Brake Rotors:
- Check for warping or grooves on the rotor surface. Measure rotor thickness; if below specifications, replace the rotor.

4. Reassemble Components

Brake Pad Replacement:
- If pads are worn, remove old pads and install new ones, ensuring they are correctly seated in the caliper bracket.
Reattach Caliper:
- Slide the caliper back onto the rotor and tighten the caliper bolts to the manufacturer's specified torque.
Reinstall Wheel:
- Place the wheel back onto the hub and hand-tighten the lug nuts.
- Lower the vehicle and tighten the lug nuts to the specified torque.

5. Brake System Bleeding (If Necessary)

If any brake fluid was lost during service, bleed the brake system to remove air. Follow the recommended procedure for the RAV4.
