it doesn’t need to have a baffle, it has 2 chambers insde the master cylinder. 1 to feed the front, 1 to feed the rear. hence if you lose a rear brake line, you still have fronts to stop the car. it’s not great, but it still stops the car. if you lose a line now, you’d have absolutely no brakes. but you’ll never listen to anyone, so why am i wasting my breath?
