Concerned braking attitude

When I brake at a stop light sometimes the brake pedal has to go all the way down and the pressure seems to give.Some days it will grab good or decent and like today the pedal nearly hit the floor and the pressure jumped it stopped the truck but what was also weird and it's happening more is my leg has to keep good pressure now on the pedal or it will have pressure releases and jump the truck forward etc.Why is this pressure wierd?

Master Cylinder is going bad. The seals are by - passing internally. Needs to be replaced.
