How do you get new BB7 pads to install in the new caliper bodies? By "new" I mean the ones with the spring steel "cap" on the opening at the "top" of the caliper unit (the side opposite the axle).
On my c. 2004 Gary Fisher, the silver calipers are closed on the side opposite the axle. On my 2015 Salsa Vaya the black calipers have an opening on that side, and they have a spring steel cap that clips into the opening. The upper "ears" on the pads extend up into that space.
Here is what it looks like from the "top" (looking toward the axle):
You can see the pads through the opening in the cap.
On the old Fisher, I would install BB7 pads just by pinching the pad-spring-pad "sandwich" and pushing the sandwich into the caliper from the "bottom" (the side toward the axle). This is how all the advice on the web tells you to install BB7 pads. On the Salsa Vaya, with the cap installed, I can only get the pads all the way in about one in fifty tries--usually one or the other pad will not go all the way in. Sometimes both pads hang up short. If I take the cap off, then the pads go in fine. I rode all the way across the U.S. with the cap off because that was the only way I could get the pads into the caliper. What's the trick?
