Hey, guys. I took my car to a mechanic to get my brake master cylinder/booster replaced. After getting it back, the car ran okay for a few days till it started choking every now and then. It eventually died and wouldn't start again. I looked under the hood and realized that all brake fluid was gone. So, I took it back to the same "professional", who has had the car for over 3 weeks and cannot figure out what the problem is.
Any help?
Are there any parts I should look into changing/replacing to see if it fixes the issue? Given, the brakes have been properly bled and lines have been checked for leaks.
Thanks

 

If you ran out of break fluid your breaks would not be working properly.

Are you blowing out a **** ton of blue smoke from your tailpipe?

 

the only common part between the brake system and the engine is the vacuum line that connects the intake to the booster. I've never heard of this happening, but I suppose if fluid got on the vacuum side of the booster, the engine would suck it in...

Is there brake fluid in the boosters vacuum hose? Or intake manifold?

 

@ mouab18c1: I used to be blowing tons of smoke, but then we changed the booster/master cylinder. we thought that one, or both may be damaged...so when we replaced them, the smoke went away.
Then I rode it for a day or so with no issues until the car started choking, till it completely died. I didn't think the problems were related, till when I was towing the car, I realized I had no brakes.

 

I'm not sure. I will have to call the guy, as the car has been in his shop (forever!) It sounds weird to me too. Maybe a damaged prop valve? Could this be it?

 

I would take it to a different shop. Thats my advice for now, headed to work so ill reply back later when I get home.

 

Got to agree with mouab18c1, if it took your "professional" 3 weeks to install a booster and master cylinder, and now he can't figure out what is wrong, I would be taking it someplace else. 94

 

"Professional" sounds like an idiot... I would that the car elsewhere... The only way brake fluid could get into your engine is through the booster vacuum hose, and thats highly unlikely. just pull the hose off and check for brake fluid in it.

 

Thanks, guys. I thought I'd give him the benefit of a doubt, since it sounds like an anomaly. But you are right. I feel like he's blowing me off just not to deal with it. I'll be towing it to a different shop on Monday...so I'll keep you posted!
