Can you fix brake line with rubber hose?

You can not use regular rubber line with a brake system. First, even with a barbed or rolled end, the clamps will not stand up to the 100+ psi. Second, brake fluid is not kind to rubber hoses. Third, the pressure will burst regular line even if the clamps held.
