Need a AO gear head

[Swampy]

My frickin Dodge is acting up again. this time ABS and Brake idiot lights are on. and its not leaking out anywhere visable out of the lines, rear drums are dry, but its eating fluid. Master Cylinder bad?

Anybody got any suggestions its a
1994 Dodge 1500 2wd pickup with 165K on her. wouldn't be surprised if it was the master cylinder.

The vacuum seal on the master cyl. may be bad. Your fluid me be collecting in front of the diaphram...........just a guess
