Solution

1. Preparation

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

2. Remove the Wheel

Use a lug wrench to loosen the lug nuts on the rear wheel.
Elevate the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the rear wheel.

3. Remove Brake Components

Remove the caliper mounting bolts using a socket set.
Carefully slide the caliper off the rotor and support it using a bungee cord or wire to avoid straining the brake line.
Take out the brake pads from the caliper bracket.

4. Inspect and Replace

Inspect the brake pads for excessive wear; if they are worn down to the metal backing, replace them.
Check the brake rotor for damage; if it has deep grooves or is warped, replace or resurface it.
Clean the caliper and bracket using brake cleaner to remove dust and debris.

5. Reassemble

Install new brake pads into the caliper bracket.
Reinstall the caliper over the new pads and secure it with the mounting bolts.
Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (typically 76 ft-lbs for Toyota RAV4).

6. Final Checks

Pump the brake pedal a few times to seat the brake pads.
Check for any leaks around the caliper and ensure everything is secure before driving.
