Just experienced brake failure. Exactly like described in post #6.
Interested to hear more about metal shavings going up in the block. Seems like it’s not actually possible.

I now have just under 100K miles and haven’t had a recurrence or any other vacuum related issues.

After my “no brakes” situation, I did find that a vacuum hose was left disconnected from the air box which may (or may not) have played a role in the pump failing.
The car also had the PSE exhaust cable unplugged ….such that the car was always in “loud” mode. I can’t see how that might cause any issues with the vacuum line running to it…. but who knows …thought I’d mention it just in case it was helpful.

Thanks for replying.
Vacuum pump was diagnosed as weak and is being replaced as we speak.
Weak meaning that it couldn’t manage more than 2 “presses” on it hégire becoming hard as rock and would quickly fully fail.

Hmm, unless the pump is outragously expensive, sounds like something that might be replaced as preventative maintenance just to be on the safe side.

Pump is a couple hundred bucks. Can be cheaper if bought from FCP.
Indy quoted ~$460 for parts and labor (turned out to be a little more as they had to investigate the issue - could have been the lines).
By the way this is a TX and CA car only so no corrosion.

Can you explain how it was tested and confirmed weak?

AxelR

I didn’t have time to ask them when I picked it up. I can check with them at some point.
