Hello people

I bought some BB7's recently, although I think they may be the older type. I noticed that the pads are loose, and also the, uhhh, piston assembly, or whatever it is that gets pulled by the cable and rotates. Is this normal?

There's a spring clip that sits between the pads to push them apart. If this is missing then the pads can be flopping around in the caliper. If it is in there then the pads will move a little but will always spread apart. The rotating assembly has some wobble to it on my BB7s.

The version 1 calipers used magnets to hold/retract the pads. Sometimes the magnets came loose and/or broke into pieces. You can use the spring "H"-clip if you want. There is also a different spring clip inside the caliper that the pads snap into. It can crack and the pads will be loose without the rotor in place.

The piston assembly may be a bit dirty though it does not really matter if it rotates or not.
