my Skoda Octavia NFL (2020-Present) has a strong vibration when braking, what's wrong?

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Remove the Wheel

1. Loosen the lug nuts on the affected wheel while the vehicle is still on the ground.
2. Use a jack to raise the vehicle and securely support it with jack stands.
3. Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

1. Remove the caliper bolts using a socket set.
2. Carefully slide the caliper off the brake rotor.
3. Inspect the brake pads for wear; if they are worn beyond specifications (usually less than 3mm), replace them.
4. Install new brake pads, ensuring they are properly seated in the caliper bracket.

4. Check and Replace Brake Rotors

1. Remove the brake rotor by unscrewing the retaining screws if present.
2. Use a dial indicator to measure the rotor's runout; if it exceeds the manufacturer's specifications (typically 0.002 inches), replace the rotor.
3. Install new rotors, ensuring they are clean and free of debris.

5. Reassemble

1. Reattach the brake caliper over the new pads and rotor.
2. Tighten the caliper bolts to the manufacturer's torque specifications.
3. Reinstall the wheel and hand-tighten the lug nuts.
4. Lower the vehicle and securely tighten the lug nuts in a crisscross pattern to the specified torque.

6. Final Check

• Recheck the brake fluid level and top off if necessary.
• Test the brakes at low speed to ensure proper operation.
