I also have 15 delux and did disc brakes all around. i was gonna do the same set up in back as you. but same problem. also when i did my vert same thing. i could never get a good answer from anyone or shop so i just did disc all around. alot more cost but better piece of mine in the long run. i think just the quality of parts are just no good. for awhile i use to try to look at other cars to see if they leaked. and most of them did. i think its just a vw thing.im sure someone has the answer but i could never get it. i know this didnt help much. but just want to let you know i fill
your frustration. i have been there.

Have the shoes been all the way adjusted out before pumping up the system?

Who made your rear w/cylinders? German, Brazil or China?

Was in the garage looking over everything again and noticed I had the emergency brake on while bleeding the brakes Embarassed

. Removed the ebrake and removed the wheels and drums and to a look and everythingn looks in place just leaking but new Confused

. cleaned it all out replaced the drums and adjusted the brakes so the drum was tight evenly on both sides. Will try again tomorrow. Wish me Luck!

Did you bleed the fronts first??

You should take the rears apart to inspect the cylinder seals to make sure they are not all jambed up.

there really isn't much to a wheel cylinder...take it apart and figure out why it's leaking.

did you replace the hard lines going to the wheel cylinders?? all of the new lines' flares i've seen recently are garbage and leak...even if you tighten the piss out of the flare nut, they will leak because they are formed improperly...probably by slave labor

I started bleeding the rear passenger side then moved to the drivers rear side then passenger front then driver front. I will open cylinders tomorrow and check them. Its kind of trippy cause they are both leaking and both new but I will check them out tomorrow.

are you sure they are leaking from inside the drum and not from where the hard line screws in?

Yeah its dry on the out side where it screws in but I pulled off the drum and there was a puddle on the bottom of the drum and I can see it leaking from the bottom of the seal.

What is this master cylinder? The 113 part number sounds like bug/ghia. Pics?

The orifice passages inside the cylinder might be affecting the rear? On my bug, when converting to all disc brakes, nothing ever worked right until I put the "new " late bug 4 wheel disc master cylinder. It looks like stock, but internally it is not. The fact that both sides just happen to be leaking at the same time makes me suspect something might be getting too much pressure, if thats possible with a wheel cylinder.

Too much pressure,from a master cylinder is not possible. The pressure pushes the seals against the sides of the wheel cylinder,making the seal.
I would return those wheel cylinders where you bought them.

Has any body used the chinese wheel cylinders it seems that is all anyone has in the area and I am not to sure about that brand.
I am carrying my kids in this bus and want something reliable.

I try to stay away from China and Brazilian parts but if I have no other choice, I'd pick Brazilian.
I just bought some T3 w/cylinders that are Varga or brazilian, from ISP west:
http://www.vwispwest.com/home.php

I would guess they have more. I was unable to find ATE or German anywhere.

EDIT: That is incorrect, come to remember, ISP West did have the German ones, they were near $80 a piece and are said to leak after sitting for awhile, like the Brazilian; I picked the $20 Brazilian ones after hearing that.

Clyde at Athens German Aircooled usually has Brazilian brake parts in stock. I got some front wheel cylinders from him a couple of months ago. Since he is close by, you can save alot on shipping and help out a local vendor at the same time!
