NORMAL BRAKE MODE
During non-antilock braking, pressure is applied through the brake pedal and fluid comes from the master cylinder into
the hydraulic unit. The normally open isolation cartridge and normally closed dump cartridge would remain in these
positions to allow fluid pressure to the calipers and the wheel cylinders. And each wheel begins locking.
