CJ 7 Brake Master Cylinder
During wheeling Saturday I lost my brakes in my '79 CJ7, haven't had
much time to diagnose it, due to yesterday being Mothers Day. My wife
was mad I even had to borrow a trailer and go back and get the Jeep
Sunday morning.
I believe it may be leaking fluid from the Mastercylinder as I am losing
fluid from both resevoirs. I could not diagnose it Saturday as it was
to covered in mud to see anything and I was busy helping our club with
the rest of our event. Picts can be seen here:
http://www.mudnuts.org/gallery/dalton04 including a rolled UniMog.
oh yeah, back to my problem....
Some of you may remember me posting last week about my brake issues due
to a sticking e-brake cable, I wonder if driving with the rear brakes
locked then out of adjustment put to much stress on my resevoir. I
looked online at NAPA and see many different choices for Master
Cylinders for manual brakes. What are the differences besides
new/rebuilt? Is there a big difference between a new and rebuilt unit?

Also more info....
In the near future I will be swapping in a rear Dana44 from a 74 CJ5,
which has 11" rear drums instead of my current 10.75" drums on the AMC
20. Should I go ahead and get the MC from a 74? But the 74 was
designed for fron drums where I will be keeping my front disks.

Re: CJ 7 Brake Master Cylinder
My guess is the rim and rubber seal on the fluid container are dirty
letting it leak out the top.

Re: CJ 7 Brake Master Cylinder
My guess is the rim and rubber seal on the fluid container are dirty
letting it leak out the top.

Re: CJ 7 Brake Master Cylinder

is what make me think the seal finally died.
What do you think about the difference when I change the rear axle to a
Dana 44? Will I need a different MC?
