ok people, I need the help

[Paukert11]

Ok so today my car just started this but when I step on the break its stiff and then a starts to sink. Now this isnt the check vacuum valve right??? or is it the Pressure Regulator. Can some one help me out?? But when my foot is all the way down on the floor the car does stop. so can someone help?? asap

If it were a vacuum leak, the pedal wouldn't sink. It seems more like you're losing pressure in your brake system somewhere. Does it sometimes seem to depress rather much without having any effect on the car's momentum?

Master cylinder or brake booster problems???

If you're not losing brake fluid, it's probably your master cylinder.
I don't think a bad break booster would cause the pedal to sink to the floor.

BRAKE booster, dammit!

BRAKE booster, dammit!

3/5 spelling it right is about as good as it gets. =/

[Paukert11]

so break booster! ok thnks

[Kerrath]

so break booster! ok thnks

Pretty sure luke was saying you spelled brake wrong. It's brake. The e goes at the end.

your problem is Not your brake booster from the limited info you gave. A problem with the booster would make it very Hard to press, not easier.
