I wrote to you yesterday about loss of brake fluid from my1992 Honda Accord. Model EX1, Eng 2.2 lt type F22A9. 4 wheel disks with ABS. Handbrake to rear disks (not drums with shoes).
I've checked all wheel calipers and hoses but no leaks. No leaks evident on the pavement when brakes applied repeatedly when stationary.
No loss of fluid from ABS tank, only from brake master cylinder. No wetness around booster.
Any ideas?
I donated $10 yesterday.
hope you can help. Thanks

No visible leak sounds like its being sucked in by the brake booster-

Let me try Oz-pull the brake master cylinder of the the booster and inspect behind it for wetness-also the the Vacuum hose for fluid

rasmataz is right,check for paint off behind booster or remove the hose like rasmataz said.
if nothing there, then you have a bypass in the primary piston in the master cylinder.
brake fluid contamination caused that,
look in the master cylinder while somebody is pumping on the brake, if you see big bubles inside, then you have bypass on the primary cup.

have a good day,
got to go
