Check for any visible leaks in the brake lines, calipers, and around the master cylinder.
3
Examine the brake pads and rotors for wear, as worn components can affect fluid levels.
4
Test the brake pedal feel; note any sponginess or abnormal behavior.
5
Scan for any diagnostic trouble codes (DTCs) related to the braking system using an OBD-II scanner.

Diagnostic Steps

Solution

1. Preparation

Tools Required: Brake fluid, funnel, brake line wrench, cloth, OBD-II scanner, jack and jack stands.
Ensure the vehicle is on a flat surface and the ignition is off.
Allow the engine to cool and engage the parking brake.

2. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Clean the area around the reservoir cap to prevent dirt from entering.
Remove the cap and check the fluid level; if low, add the appropriate brake fluid (typically DOT 4 for Skoda vehicles).

3. Inspect for Leaks

Visually inspect all brake lines, fittings, calipers, and the master cylinder for signs of leaks.
Use a cloth to wipe areas that may appear wet to determine if they are leaking.
If leaks are found, mark the location for repair.

4. Replace Brake Fluid (if necessary)

If the fluid is contaminated or has absorbed moisture, it may need to be replaced:
- Use a brake line wrench to disconnect the brake line from the master cylinder.
- Allow old fluid to drain into a container.
- Reconnect the brake line and refill the reservoir with new brake fluid.
- Bleed the brakes to remove air from the system:
  - Start at the wheel farthest from the master cylinder and work towards the closest.
  - Open the bleeder valve and pump the brake pedal until fluid flows without bubbles, then close the valve.

5. Final Checks

Recheck the brake fluid level after bleeding and ensure it is within the recommended range.
Replace the reservoir cap securely.
Dispose of any used fluid according to local regulations.
