my Skoda Octavia's brake warning light is on, what should I check?

Solution

1. Preparation

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

2. Check Brake Fluid Level

• Open the hood and locate the brake fluid reservoir.
• Remove the cap and check the fluid level against the minimum and maximum marks.
• If low, add the appropriate brake fluid (DOT 4 recommended for most models).

3. Inspect Brake Pads and Rotors

• Remove the wheel using a socket set.
• Inspect the brake pads for thickness (minimum thickness is typically 3mm).
• Check the rotors for grooves, scoring, or excessive wear.
• Replace pads or rotors if necessary, following standard replacement procedures.

4. Examine Brake Lines and Hoses

• Visually inspect all brake lines and hoses for cracks, abrasions, or leaks.
• If any leaks are found, replace the damaged lines or hoses.
• Ensure all fittings are tight and free of corrosion.

5. Test Brake Warning Switch

• Locate the brake warning switch, typically mounted near the brake pedal.
• Disconnect the switch connector and test with a multimeter for continuity when the pedal is pressed.
• Replace the switch if it is faulty.
