I could not have said this any better except to add that if you go buy all this mondo brake stuff and can't lock the fronts, you're wasting your time. If you can't lock the front brakes, you're leaving stopping ability on the table.
True. It is just a question of force applied to the brake pedal, unless something is bottoming-out so you are no longer pressing on just the hydraulic fluid. Might need to use both feet if poor boost with disk brakes.
