TO those with leaky caps, have you tried lowering the fluid level a bit?

Yes, I used a rag and soaked out a bit of fluid. It is at the bottom of the tubes, if not a bit lower. There is no full marking on them though.

I've had ZERO problems with leaking caps.

Leaky caps on mine also. Lowering the fluid level helped,but didn't cure it. Funny thing is, leaking cap is the main reason I ditched the original iron cyl.

Same here....thought screw on caps would eliminate the possibility of leaking...little did I know.

I just wanted to add that i got one of the master kits with adapter from eberg for a 69 b body with front disc and changed over to bigger brakes and new dot 5 fluid and have not had any kind of a problem in almost 2 years

Hi-I put those aluminum cylinders on my 71 dart, 69 fury,and 74 duster. None worked no mater what I did, including months( a few hours at a time) of bleeding, including power bleeding etc...I thought I was the only one with weeping caps! I went to the junk yard and some used ones that worked a bit better. I still dont have decent brakes after putting the iron back on the Duster! I even bought a brake resevoir and added it and still little brakes. Its a gamble every time I hit the road!

Did you install later rear wheel cylinders?
If you use the older style rear cylinders you can have problems with getting the system bled. E-Burg wrote about it in Mopar Action a few times.
I had a real problem with soft pedal feel in my 74 Swinger that I had installed an aluminum master, untill I installed the rear wheel cylinders out of a late 70s pickup.
very solid pedal from that day on and no more rear wheel lock up.
