my Skoda Octavia NFL (2020-Present) has a hard brake pedal, what should I do?

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a flat surface and set the parking brake.
• Wear safety gloves and goggles for protection.

2. Inspect and Replace Brake Fluid

• Sub-steps:
  1. Open the brake fluid reservoir cap.
  2. Inspect the fluid level; if low, top it up with the manufacturer-approved brake fluid (DOT 4).
  3. If the fluid is contaminated, proceed to replace it.
• Tools Required: Brake fluid, funnel, rags for spills.

3. Check and Repair the Brake Booster

• Sub-steps:
  1. Locate the brake booster (usually mounted on the firewall).
  2. Inspect the vacuum line for damage; replace if necessary.
  3. If the brake booster is faulty, disconnect the vacuum line and remove the master cylinder from the brake booster.
  4. Unbolt and remove the brake booster from the firewall.
  5. Install the new brake booster in reverse order of removal, ensuring proper torque specifications (consult service manual for specific values).
• Tools Required: Socket set, torque wrench, vacuum line.

4. Test and Inspect Brake Components

• Sub-steps:
  1. After repairs, inspect brake pads and rotors for wear; replace if necessary.
  2. Bleed the brake system to remove any air bubbles.
  3. Reassemble any components that were removed during the inspection.
• Tools Required: Brake bleeder kit, wrench set.
