No, I got them to work fine. I could bleed the dho4s in a parking lot with body armor on. I did multiple times. I had them working perfectly, in the lot. As soon as you got on them in a stressful situation, they were worthless. I believe it was due to the small pad size compared to any other pad. They howled constantly. They faded instantly. And he when you got back to the lot, they worked perfectly with zero compression in the lever. I hope you're talking about the m4s, and not the dh04s, because the dh04 was a terrible brake, but it looked nice. Mine even had the mini levers.Ok, I gotta ask. You couldn't get DH04s/M4s to work nor Gustavs?
The Gustavs were set up fine, they just had huge lever blades, three finger style, so I was never fully comfortable squeezing them. Combine that with a wet day at highland and the wheels broke free instantly. I'm sure I could have gotten them sorted out in time, but I sold the bike before investing in two finger levers.
