I'm looking to modify either a Shimano CX-50 or CX-70 brake. I haven't had a chance to look at one of these in person yet, so I don't know if it will work.
What I want to do is either replace or shorten the spacer between the pad and the brake ( see attached pic ). I don't know how that spacer is kept in place. Does the screw screw into that, the pad or does the pad have a pole that goes the the brake arm. Could I use a shorter screw once the spacer is replaced? Is it needed? Does it come with different size spacers?
If anyone has any advice or pictures of this assembly, I would appreciate it.
Or, is there anything proprietary about the brake that would prevent me from using the shoes from another brake, like the R550 without the CX-50/70 spacer?
