Blew into the hose into the booster with my mouth, not sure it did anything. The brakes light are still stuck on when I connect the battery, very annoying. Tried pulling the brake pedal back and still no luck. I have no idea whats going on. Need help!

with your mouth blow into booster she might have a split diaphragm

okay found a live wire with a plug going to the battery that might be the cause for the brake lights staying on. If i disconnect it the brake lights go off completely and so do the headlights. If i leave it on the headlights work but the brake lights stay on. Argh. What do i do?

still doing the rev thing. Also forgot to mention that the brake lights won't go off after a swapped the hose too. What do you guys think it could be?

Okay just tested it and the engine revs only when I hit the brakes and then again when I let go of them, not when I hold them down.

the hose is teh vaccum line to the brake booster, the valve is a one way valve so that the booster holds vaccum

what happens when you hold your foot on the brakes? does the engine rev up and stay up. or does it just go up then back down to normal again?

Tonight, while looking around under the hood, I found a hose that goes from my brake booster to a little valve on the intake manifold into my A15 that looked damaged and flattened. Thinking that this was probably not good, I went out and bought a new hose line, disconnected the old one from the intake and then the brake booster and replaced it, screwing it down on each end with some hose clamps like what was done before. Everything is normal except when I touched the brakes the first time the pedal was stiff. Touched it a few more times and it was better but the engine revs up about 500 rpms from idle...is this normal?

What does the hose do and what is the valve pictured on my intake do?

Just worried I've done something wrong.

Cheers.
