Have a 93 with a 5.0 and I'm losing brake fluid. It's leaking from a part on the drivers side of the motor underneath the master cylinder. Anybody know what this is ??

 

Take a picture. It could be master cylinder or a rusty line

 

Not exactly sure what your referring to but i`ll guess it`s the RABS (Rear Anti-lock Brake Solenoid ) bolted to the frame ?? But first,,have you replaced the steel brake lines. They rust out and leak. You`ll need to have a good look at them, and really, if they are original, replace them all. Could be the solenoid but usually it`s the lines. Probably not what you wanted to hear but it is 22 yrs old .

 

That's one of the parts

 

And this is the other, had to remove the wiring cause it kept blowing the fuse for the brake lights and I know it has something to do with the speed control

 

Usually the line leaks where it joins the rubber flex line to the left front wheel.
Fordtuff is right about replacing the lines. I've had more than a few of these trucks and the FIRST thing I do is replace all the steel brake lines. All of them. If they're not new, you can't depend on them, and they're kind of important.

 

The pictures just loaded up. Yes you should have new brake lines and possibly a RABS valve. I can't quite tell what that 2nd pic is.

 

I guessed right, lol...The second one looks like the remains of a pressure switch. Maybe part of trailer tow package ? Don`t have one of those on mine. Looks like the lines are the originals .

 

Replace the switch and the line at valve for the rear abs.
