Brakes are designed with two hydraulic circuits to provide redundancy. In diagonally split braking, opposite corners are connected to the same circuit: front-right with rear-left on one circuit, and front-left with rear-right on the other. Front-wheel-drive vehicles typically bear more braking load at the front, so this diagonal arrangement helps ensure you still have braking on two wheels even if one circuit fails, improving safety without needing a separate circuit for each wheel. The other terms aren’t standard descriptions of how two circuits are arranged, and all-wheel braking isn’t a typical setup for the two-circuit design used today.
