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.

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.

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

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.

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.
