Master Cylinder question
I replaced my hydroboost unit about 10,000 miles ago. Today I noticed it was wet under the unit. Only this time, it's not red PS fluid, rather, it is brake fluid. So, I assume the master cylinder is leaking and winding up under the hydroboost unit via gravity. Or at least that's my theory.
Anyway Rockauto lists 2 motorcraft master cylinders.
One is BRMC-26 for Hydroboost
The other is BRMC-27 for speed control.
I have obviously Hydroboost, but also have speed control. Anyone go through this and figure out the right one?
Thanks!

Do what Stewart says first because that could be your leak. As far as the master cylinder goes, they have all been replaced by the BRMC-27.
