Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, socket set, brake cleaner, safety glasses, gloves.
Raise the vehicle using a jack and secure it with jack stands.
Remove the rear wheels using a lug wrench.

2. Remove Brake Components

Sub-steps:
1. Remove the caliper mounting bolts using a socket wrench.
2. Carefully slide the caliper off the rotor and support it with a bungee cord or similar (do not hang it by the brake line).
3. Remove the old brake pads from the caliper bracket.
4. If necessary, remove the caliper bracket by unscrewing the bolts and set it aside.

3. Inspect and Replace Brake Parts

Sub-steps:
1. Inspect the brake rotors for scoring, warping, or excessive wear, and replace if necessary.
2. Clean the rotor surface with brake cleaner before installation of new pads.
3. Install new brake pads into the caliper bracket, ensuring they are positioned correctly.
4. Compress the caliper piston using a brake caliper tool to make room for the new pads.

4. Reassemble Brakes

Sub-steps:
1. Reattach the caliper over the new brake pads and secure it with mounting bolts.
2. Torque the caliper bolts to the manufacturer’s specifications (usually around 79 ft-lbs for RAV4).
3. Reinstall the wheel and hand-tighten the lug nuts.

5. Final Checks

Lower the vehicle and torque the lug nuts to the specified value (typically 76 ft-lbs).
Pump the brake pedal a few times to ensure proper seating of the pads.
