So I went through a big puddle the other day and now when I hit my brakes the peddle barely moves and kind of jumps around, I don't know how to explain it.. But when all this is going on, I hear a screaming noise coming from my engine, somewhere around the brake fluid resevior.. Like its choking/gargling. The fluid looks fine, and is topped off.. any ideas of what it could be?

 

do you have a CAI and how deep was the puddle . i hope you didnt get water in the engine

 

Could be water in the brake servo, would explain the hard feeling on the brakes, try disconnecting the servo pipe and see if it's full of water...

 

I have a k/n cai.. And where is the servo pipe? I have an 02 4.7 if that helps, and the puddle wasn't too bad.. Maybe a foot, but nothing crazy

 

On your brake servo there should be a pipe going into it, about 1/2" dia, it should have a non return valve on the pipe somewhere as well. If the non return valve is working properly you'll hear air entering the servo as you pull the pipe out, if not that may explain why your brakes are hard.

Did you hit the brakes as you went through the water?
