Description
Brake fluid is hygroscopic. That means it absorbs moisture from its environment. If the brake fluid absorbs too much moisture, the wet boiling point is lowered significantly, which increases the risk of total brake system failure under extreme loads.
Example Downhill: If the foot is constantly on the brake, the temperature of the brake fluid rises. When the boiling point is reached, the bound water begins to boil and vapour bubbles form in the brake system.
The Result: No pressure can build up in the brake system = total brake failure!
DOT MAKES THE DIFFERENCE
THE RIGHT TEXTAR BRAKE FLUID FOR EVERY NEED
Brake fluid should be changed every two years. When choosing, manufacturer‘s specifications must be observed because there are different classes:
- DOT 3, 4, 5 and 5.1 differ mainly in terms of boiling point and cold viscosity.
- DOT 3, 4 and 5.1 are glycol-based,
- DOT 5 silicone-based.
The higher the DOT class, the higher the boiling temperature and wet boiling point. Higher DOT classes tend to allow for longer maintenance intervals. The DOT standards are based on the American FMVSS-116 standard of the Department of Transportation (DOT).
