Felt B2 rear mounted brake sticking- any advice?
Hey folks. I've got a Felt B2 which has the rear brake hidden down at the bottom and behind the seat post. The brake calipers are kinda "sticking" and the action of the break lever is squishy and doesn't really realease correctly. FYI- these are the stock brake calipers that came with the B2- pretty low end crap stuff (obviously where they saved some $$).
Anybody run into this before and have any idea how I fix it? I think I might need a special wrench to adjust the bolt that holds the caliper to the bike?? Would that adjust the caliper action?

Nemo, Can't provide specific stuff on this brake. However, to save you some hassle if you decide to switch. You'll need shimano 7800 series ( I had to go to ebay to find it). The B series and DA are the same frame just different carbon.
From the folks at GAG in Chicago (who did my build)
2) The rear Ultegra brake you had us order is incompatible with the Felt DA frame (the front brake is fine). In the past, I have also found that the SRAM Red, Force, Rival, and Shimano Dura-Ace 7900 rear brake is incompatible with the DA. The incompatibility is due to the arch of the brake hitting the frame. The only common brake I have found to fit the Felt DA is the Dura-Ace 7800.
If the brakes worked OK at first, it could be that the housing got kinked or that it is interfering with the cable moving easily. To test that, you can undo the cable fixing bolt on the caliper and feel how smoothly the cable runs.

Just cut the cable - brakes are for wussies
For better or worse, integrated or otherwise hidden or non-conventional brake designs I think are only going to become more and more prevalent on the next generation of TT bikes. From here on out, I don't think we'll see many conventionally mounted rear brakes (look at the Felts, P4), and now we'll get to deal with the fun of inaccessible integrated front brakes too (Speed Concept, Shiv).
As for the HED C2 rim, the Stinger 6 is actually wider at its apex than the Stinger 9 (or at least it seems), such you can not even mount it even with zero cable tension on the front brake without modified pads or calipers. I’d have to remove the front brake all together… maybe that’s not such a bad idea… I’ll pull the brakes, get a Bianchi Pista, a brooks saddle and match the colorway in accordance to my novelty mustache. As far as I know, there’s no USAT rule prohibiting hipsters... but ahem, back to reality. The 2010 Zipp 303 uses a similar width rim to the C2 I believe, it'll be interesting if the full line of Zipps moves in the same direction as HED.
