why is my Toyota RAV4 XA50 (2019-2024) making a grinding noise when braking

Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Park the vehicle on a level surface and engage the parking brake.
• Disconnect the battery to ensure safety while working on the braking system.

2. Remove Wheel Assembly

• Using a socket set, loosen and remove the lug nuts from the wheel.
• Use a jack to lift the vehicle and secure it on jack stands.
• Remove the wheel to access the brake assembly.

3. Inspect and Replace Brake Pads

• Remove the caliper bolts using a socket wrench and carefully slide the caliper off the rotor.
• Support the caliper with a bungee cord to avoid strain on the brake line.
• Remove the old brake pads from the caliper bracket.
• Measure the thickness of the old pads; replace if they are below the manufacturer’s specifications (usually less than 3mm).
• Install new brake pads in the caliper bracket, ensuring they are seated correctly.

4. Inspect and Replace Brake Rotors (if necessary)

• Check the rotor for any scoring, grooves, or warping.
• If replacement is necessary, remove the rotor by unscrewing any retaining screws and sliding it off the hub.
• Install new rotors, ensuring they are clean and free of debris.
• Torque the rotor retaining screws to the manufacturer's specifications.

5. Reassemble Brake Components

• Reinstall the caliper over the new brake pads and rotor.
• Tighten the caliper bolts to the specified torque.
• Reinstall the wheel and tighten lug nuts in a crisscross pattern to the manufacturer’s torque settings.

6. Final Checks

• Reconnect the battery.
• Pump the brake pedal several times to ensure proper operation of the brake system.
• Check brake fluid level and add fluid if necessary.
