brake cylinder or maybe something else?

had what i thought was brake fluid under the rear right wheel area.. like under the shock on the floor.

pretty good pool of it

guy at the shop when i got my 31s put on yesterday said it was a leaking wheel cylinder

i dont think its brake fluid now because the resivior still has fluid in it... like just a little below the full mark.

what else could it be and what should i look for?

the brake line inthe area looks good

its not leaking out of the wheel area like the back of the drum brake onto the rim or anything..

it might be leaking from above the shock

it almost looks like the shock is just blown and leaking but this seems like too much fluid to just be a shock

if you want i can post pics

keak

my bet would be the shock-wipe it bown and clean it good andcheck it again- then again if it is on concrete all it takes is one drop to make a good size puddle.

What axle, Dana 35c or Dana 44, do you have in the rear? If it's a Dana 44, it sounds like a leaky axle seal to me which is neither difficult nor expensive to replace.

D35 is ok depending on your driving/use of the jeep/tire size

D44 is the prefered axle to have.


The front axle is a D30 ....its fine up to 35/36'' tire.

well the brake cylinder bolt in the rear of the drum was rusted on pretty good, so i just rebuilt it. cleaned it out real good and used the new parts on the old one.

the other side looked fine as well so im gonna hold off.

brakes on the leaking side were dirty but not too bad at all, probably due to only driving it about a mile and a half to my buddies house to fix it since the leak started.

so i took the brakes off and cleaned em real good with brake cleaner and brillo, and put those puppies right back on.

went ahead and bled the brakes while i was there.

they have enough tread left to assume they were replaced when the front brakes were replaced, which was october this year, and 1200 miles ago. so needless to say im taking my new shoes and spring kit back.

and yes the shock is leaking too lol.

only thing left fluid wise is the power steering flush.
