I bought a brake combo with the gold anodized power booster and the factory style looking master cyclinder with the side bleeders. First one leaked out the back right away and they warranties it. Got the replacement and it worked for a week and now it leaks between the master and booster. It was through our sponsor for brand type reference only. Both where great help getting a replacement. I been bleeding brakes for 30 years and never had this problem. Brakes are not partially engaged, seam to work right, I had rod in right hole, I just want to resolve this. Not going to send 2nd one back at this point. Bench bleed the wheel bleed. All new stuff at 4 corners. What am I doing wrong?
