No Brakes!!

[JaeTea]

Since it was somewhat warm out today I figured I'd move my car that's been sitting outside all winter to avoid flat spotting my tires.

Well when I released the parking brake, I stepped on the brake pedal and nothing!!! The car rolled straight down the driveway!

Popped the hood and there was zero brake fluid in the master cylinder, it was completely full before I parked it for the winter. So I filled that up and pumped the brake pedal for about 15 minutes and still nothing.

Not sure where all the brake fluid that was in the master cylinder originally went.

try bleeding the brakes

bled the brakes and still the same. Pedal goes straight to the floor with no resistance. The level in my BMC keeps going down too.

you have a leak somewhere in the system. check all the lines, also check below booster and inside right behind booster, just incase the master is leaking.

If there are no puddles or marks under the car where you parked it its most likely a bad master cylinder. check inside like japslapsiliva said. also check the engine bay the fluid may not of reached the ground. not likely but is still a possiblility

also if the fluid is in your car, or on the frame rail etc....remove all of the fluid....sand and re-paint the surface. brake fluid is very caustic and will promote rust if left untreated.

The fluid is probably leaking into your booster.
