Basically what you are doing by putting it in the rear line is PREVENTING the fluid from applying the rear brakes. You do this by turining on the line lock BEFORE applying pressure to the brakes, thus preventing fluid flow to the rear brakes. You are also allowing control over your front brakes, allowing you to creep forward.
