I have Specialized TriCross bike with disc brakes. The stock setup uses SRAM BB5 brakes with barrel nut located at the very end of the brake cable (no barrel nuts at the levers, no inline barrel nuts). The nut actually works against the "cable guide" arm of the brake, as shown in this picture
I'm planning to switch from BB5 to BB7. However, the similar "cable guide" arm (whatever the proper name for that arm is) on BB7 has some sort of long plastic (or rubber) sleeve sticking out of it. I presume the end of the cable goes into that sleeve
So, what would be the proper way to install BB7 on my bike if I want to keep my current brake cables? Can I just remove and throw away the black sleeve and end up with the setup similar to what I currently have on BB5? Or is it more complicated with BB7?
