[jakemprater]

so for the last few days my brakes have been pulsing pretty bad when applied. and today my pedal just fell to the floor and after a few seconds of pumping it came back up. i think i need a booster. im not sure can someone please help!!!! THANKS!

Sounds like a master cylinder to me. Check for fluid leaks in your system, including your rear wheel cylinders. Most of the time, when your booster goes bad your pedal will be hard and you'll have to use two feet to get the brakes to apply.

I'd have to say its the master cylinder also.
sounds like it is bypassing the fluid.

Sounds like to me you might need a master cylinder, if your brake pedal is goin to the floor and you pump it its that piston that is retractin buts not holdin pressure
