Brake Booster Question

[Socrates]

Just wondering if the vacuum line that connects to the brake booster can be replaced with any vacuum line, as long as it fits, or does it have to be replaced with the oem hard rubber one that it came with?

I used fuel line and from time to time my brakes will lock up on me, or rather engage without me pressing down on the pedal. I know it is not the front caliper because I just replaced both right and left I also recently replaced the brake booster.

thanks
