02 ZL1#51 losing brake fluid??

[GRB]

Yesterday my brake light came on. When I got home my master cylinder was almost empty. I've got almost 200 miles on the car.
Still waiting for the C5R motor to be completed. I wonder if the line lock could have caused this. I can't find any obvious leaks. Anybody else have this happen? /ubbthreads/images/graemlins/dunno.gif

This may sound silly, but I'am wondering if Matt and the guys completely refilled the master after the line-lock install.

With no obvious leaks its a thought.

That's a possibility but why didn't the light come on sooner? Maybe there was some air in the lines that has worked it's way out. /ubbthreads/images/graemlins/dunno.gif

Yes, air could be a problem. Bleeding the brakes on 98-02 F-bodies is tricky. GM says to bench bleed the master off the car, reinstall and bleed the lines.

Best bet is to make sure there are Zero fluid leaks anywhere. After that, follow the the bleeding procedure in the shop (Helms) manual.

As you know, brake fluid doesn't evaporate, it only leaks out.
