why does my Toyota Highlander XU70 (2020-Present) vibrate when braking

Solution

1. Preparation

• Tools Required:
  • Jack and jack stands
  • Lug wrench
  • Torque wrench
  • Brake cleaner
  • Runout gauge
• Safety Warnings:
  • Ensure vehicle is on a flat surface and securely supported by jack stands.
  • Wear safety glasses and gloves.

2. Remove Wheel

1. Loosen lug nuts slightly while the vehicle is on the ground.
2. Lift the vehicle using the jack and secure it with jack stands.
3. Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

1. Check the brake pads for uneven wear or damage.
2. If worn or damaged, remove the caliper by unscrewing the caliper bolts.
3. Slide the caliper off the rotor and support it with a bungee cord (do not let it hang by the brake line).
4. Remove old brake pads and replace them with new ones.
5. Apply brake grease to the back of the new pads to prevent squeaking.

4. Inspect and Replace Brake Rotors

1. Measure the rotor thickness using calipers; if below minimum specifications, replace the rotors.
2. If the rotor is warped, remove it by unscrewing the retaining screws (if applicable) and pulling it off the hub.
3. Install new rotors, ensuring they are clean and free from oil.
4. Torque rotor retaining screws to manufacturer specifications.

5. Reassemble and Test

1. Reinstall the brake caliper over the new pads and torque caliper bolts to specifications.
2. Put the wheel back on and hand-tighten the lug nuts.
3. Lower the vehicle to the ground and torque the lug nuts in a star pattern to the manufacturer's specifications.
