my Skoda Octavia NFL (2020-Present) vibrates when I brake, what could be the issue?

Solution

1. Preparation

• Gather tools: socket set, torque wrench, jack stands, brake cleaner, and protective gloves.
• Park the vehicle on a level surface and engage the parking brake.
• Disconnect the battery for safety if required by local regulations.

2. Remove Wheel

• Loosen the lug nuts slightly while the vehicle is still on the ground.
• Use a jack to lift the vehicle and securely place it on jack stands.
• Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Rotors

• Inspection: Use a run-out gauge to measure the rotor for warping. If the run-out exceeds the manufacturer's specifications, replace the rotor.
• Replacement:
  1. Remove the caliper by unbolting it and hanging it with a bungee cord (do not let it dangle by the brake line).
  2. Remove the brake rotor by loosening the retaining screws (if applicable) and sliding it off the hub.
  3. Install the new rotor, ensuring it is seated properly.
  4. Reattach the caliper and torque the bolts to the manufacturer's specifications.

4. Inspect and Replace Brake Pads

• Check the brake pads for wear; if they are below the minimum thickness, they should be replaced.
• To replace, remove the caliper bracket bolts, slide out the old pads, and insert new pads in the same orientation.
• Reinstall the caliper and torque to specification.

5. Reassemble and Test

• Reattach the wheel and hand-tighten the lug nuts.
• Lower the vehicle from the jack stands and tighten the lug nuts to the manufacturer's torque specification in a star pattern.
• Reconnect the battery and conduct a test drive to ensure the issue is resolved.
