If it is not an emergancy brake, why are brake line locks illegal in california?
I don't think it's so much that they're illegal as that they don't qualify as a parking brake. To be legal, a parking brake needs to be independent of the service brake system, which a line lock is not. If you were to blow a hydraulic line, for example, a line lock wouldn't help.
There are some disk brake systems that use the same calipers with a mechanical actuator, and there are air-braked vehicles with spring brakes that share the same foundation brakes, and they're obviously legal. So I don't know exactly what the law says, but that's the basics of it.
If you want to look it up, it should all be in the Federal Motor Vehicle Safety Standards.
