So i was changing my rear rotors today and bled out the rear passenger brake line and master cylinder. I didn't get around to doing anything else but...

when i apply the brake hard my rpms dip, and once or twice the car has shut down. There is a lot of hissing noise coming from the front two brakes or somewhere in the center of the engine and only occurs when i apply the brake hard (ie. as far as it goes). Is this just air in the line from old fluid - which i will flush out tmmrw or is this a bigger issue? Any advice would be greatly appreciated .

Did u bleed the master into itself

Do you mean empty out the master so that it sucks in air? Then no. I topped it up after about 8 or 9 applications. Reading online, could it possibly be a booster vaccum leak?

The master has two bleeders. You put a hose on it and run it into the master thru the top. One ata time

I will do that. What would be the purpose of that? To release any air built up in the master itself?

 

[chrisW]

Yes. That's right

Did you run the master dry?

Meggie knows her brakes! :wink:

Did you run the master dry?

No, i topped it off pretty frequently. How would running the master dry contribute to the engine shutting off? I've been ridiculously busy with work, so hopefully i can get to this soon and report back to you lovely folk

Gill I think you have a problem with the power steering pump. The 01Bullitts use a hydrolic pressure to boost the brake master cylinder.
The problem could be just low fluid or the pump itself . Vacuum should not have anything to do with the brakes.

It may be the pump is putting a lot of drag on the belt and at a low RPMs the engine stalls. :b01:

I was just going to say it's a booster problem but the bullitts have a hydraulic system.
