Signs of Brake Wear in a 2021 Toyota Highlander (Fourth Generation)

When assessing the brakes of a 2021 Toyota Highlander, it’s important to recognize the signs of brake wear to ensure safety and performance. Here are the common symptoms, diagnostic steps, and repair instructions related to brake wear.

Tools Required
  • Jack and jack stands
  • Lug wrench
  • Torque wrench
  • Brake pad thickness gauge
  • Digital caliper (for measuring rotor thickness)
  • Brake cleaner
  • Safety glasses and gloves
  • Brake fluid (if needed)
  • Torque specifications for bolts (refer to the vehicle’s service manual)
Repair Instructions
1. Brake Pad Replacement

Step 1: Preparation

  • Park the vehicle on a flat surface and engage the parking brake.
  • Loosen the lug nuts slightly while the wheel is still on the ground.

Step 2: Lift the Vehicle

  • Use a jack to lift the front or rear of the vehicle, depending on which brakes are being serviced.
  • Secure the vehicle with jack stands.

Step 3: Remove the Wheel

  • Remove the lug nuts completely and take off the wheel.

Step 4: Inspect Brake Components

  • Visually inspect brake pads, rotors, and calipers for wear or damage.

Step 5: Remove Caliper

  • Use a socket wrench to remove the bolts securing the caliper.
  • Carefully slide the caliper off the brake pad and hang it securely (do not let it dangle from the brake line).

Step 6: Remove Old Brake Pads

  • Slide the old brake pads out of the caliper bracket. Measure their thickness using a brake pad thickness gauge.

Step 7: Install New Brake Pads

  • Apply brake lubricant to the backing of the new pads to prevent squeaking.
  • Slide the new pads into the caliper bracket.

Step 8: Reinstall Caliper

  • Compress the caliper piston using a c-clamp or brake caliper tool to allow room for the new pads.
  • Reinstall the caliper over the new pads and secure it with the bolts. Torque to specifications.

Step 9: Reinstall Wheel

  • Place the wheel back onto the hub and hand-tighten the lug nuts.

Step 10: Lower the Vehicle

  • Carefully lower the vehicle back to the ground.

Step 11: Torque Lug Nuts

  • Once on the ground, use a torque wrench to torque the lug nuts to the manufacturer’s specifications.
2. Rotor Replacement (if needed)

If rotors are worn or damaged, follow these additional steps:

Step 1: Remove Caliper and Pads (as above)

Step 2: Remove Caliper Bracket:

  • Use a socket wrench to remove the caliper bracket bolts.

Step 3: Remove Rotor:

  • If there are retaining screws, remove them using a screwdriver.
  • Slide the rotor off the hub. If it's stuck, gently tap with a rubber mallet.

Step 4: Install New Rotor:

  • Place the new rotor onto the hub and secure it with retaining screws if applicable.

Step 5: Reinstall Caliper Bracket and Caliper:

  • Reinstall the caliper bracket, followed by the caliper with new brake pads as previously described.
Final Steps

  1. Test the Brakes:

    • Before driving, pump the brake pedal a few times to ensure proper contact between the pads and rotors.

  2. Check Brake Fluid:

    • Ensure the brake fluid reservoir is filled to the appropriate level.

  3. Test Drive:

    • Conduct a short test drive to confirm that the brakes are functioning properly and listen for any unusual sounds.

By following these steps, you can effectively diagnose and repair brake wear issues in a 2021 Toyota Highlander, ensuring safe driving conditions.
