Who is right about a "longitudinally split" brake system? Technician A: Each master cylinder piston operates the brake assemblies on opposite corners of the vehicle. Technician B: One master cylinder piston operates the front wheel brake assemblies and the other piston operates the rear wheel brake assemblies.
