- Preverite stanje tekočine: Brake fluid should be clear or light amber. Dark or cloudy fluid may indicate contamination or degradation and should be flushed.
- Izpiranje zavorne tekočine: Follow your vehicle manufacturer's recommendations for brake fluid flush intervals, typically every 2-3 years or 30,000-45,000 miles.
- Preverite puščanje: Regularly check around the master cylinder, brake lines, calipers, and wheel cylinders for any signs of brake fluid leaks.
