Your constant 12v feed is connected to terminal 30 and is output thru terminal 87a, this will provide a constant 12v feed to whatever circuit you require when you are not applying the brakes. Connect a wire from the output side of the brake light switch to terminal 86, when you apply the brakes, the relay will interrupt your constant 12v feed until you release the brakes.
