Master cylinder

[Geoffrey]

In the 2.3 ford Master Cylinder, does anyone know if the rear reservoir (the larger one) controls the front or the rear brakes?

I discovered mine is nearly empty but is not leaking from the Master Cylinder. The brake fluid is also not leaking out of the “junction box” below it. I do believe it is leaking from one of the lines though. According to the puddle, it looks like it is dripping somewhere near the center of the car so I’m assuming the rear brakes?

I’m finding it difficult to determine where though. Does anyone know of any dyes or something similar I can put in there to make the leak more apparent(or any other good tricks)?

    Thanks

 Geoff, Refill the mastercylinder reservior ,jack up the car , have someone depress the brake pedal while you are under the car and look for where the fluid is leaking. The pressure on the system should cause the fluid to leak in sufficient quanity to enable you to see the problem.Be sure to have the car supported so it  does not fall on you when the person gets into the seat to mash the brake pedal.We don’t want to loose a member because of his car landing on top of him.

Thanks Larry,

Yeah, I love my car and all, but I don’t want to die under it. Thanks for the tip-

Yeah, the larger one is the rear brakes. If you are pretty sure it’s leaking in the lines anywhere, go ahead and change out the lines. I’m flushing out the fluid in my system this weekend.  With cars this old, if it’s leaking anywhere there’s a good chance it will start leaking in another spot due to corrosion from water contamination. Since it’s getting winter time, just make the brake upgrades your next project and replace the lines.
