my Skoda Octavia's brake lights are stuck on, what could be causing this?

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative terminal of the battery to prevent electrical shock.
• Ensure the vehicle is parked on a flat surface and the ignition is off.

2. Inspect Brake Pedal Mechanism

• Check for any obstructions preventing the brake pedal from returning to its resting position.
• If necessary, clean and lubricate the pivot point of the brake pedal.

3. Adjust or Replace Brake Light Switch

• Locate the brake light switch, typically mounted near the top of the brake pedal.
• Adjustment:
  • If the switch is adjustable, reposition it so that it is triggered correctly when the pedal is released.
• Replacement:
  • If the switch is faulty, disconnect the wiring harness.
  • Remove the switch from its mounting bracket.
  • Install the new switch by reversing the removal steps.
  • Reconnect the wiring harness.

4. Test Electrical Circuit

• Use a multimeter to check for voltage at the brake light switch connector.
• Ensure that there is no voltage present when the brake pedal is not depressed.
• If voltage is present when it shouldn't be, investigate further into wiring and relay issues.

5. Reassemble and Test

• Reconnect the negative battery terminal.
• Test the brake lights by pressing the brake pedal to ensure they turn on and off as intended.
• Conduct a test drive to confirm proper operation.
