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!
