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

Solution

1. Preparation

• Gather all necessary tools and parts.
• Ensure the vehicle is parked on a level surface and engage the parking brake.
• Disconnect the battery to ensure safety while working on the brake system.

2. Inspect and Replace Brake Pads

• Sub-steps:
  1. Remove the wheel to access the brake assembly.
  2. Inspect the brake pads for uneven wear; replace if worn beyond specifications (usually 3mm).
  3. Use a torque wrench to tighten the caliper bolts to manufacturer specifications (typically around 30 Nm).

3. Check and Resurface or Replace Brake Rotors

• Sub-steps:
  1. Measure the thickness of the rotors using a micrometer; replace if below minimum thickness (usually 22 mm for most models).
  2. If warping is detected, resurface the rotors or replace them as necessary.
  3. Clean the rotor surface with brake cleaner before reinstallation.

4. Inspect Wheel Bearings

• Sub-steps:
  1. Lift the vehicle and secure it on jack stands.
  2. Grab the wheel at 12 and 6 o'clock positions and check for play; replace bearings if excessive movement is felt.
  3. Repack bearings with high-temperature grease if serviceable or replace with new units.

5. Check Tire Condition and Balance

• Sub-steps:
  1. Inspect tires for uneven wear, bulges, or damage; replace if necessary.
  2. Ensure tires are properly inflated to the manufacturer’s specifications.
  3. Have tires balanced if vibration persists after brake repairs.
