I have reviewed a few of the posts on placing a recessed nut rear brake onto the bike. I noticed a few people have mentioned that you need to bore out the hole with a 5/16" drill bit going from the seat post direction toward the rear of the bike. I assume that you don't go all the way through? I did buy a rear brake and I thought I was going to be able to fit it on the bike. However, I was thinking, could I just buy a rear brake that is old style and uses washers and nuts? Any suggestions on where to buy and what would be a good way to look for them?
Any help appreciated
Plus, to drill I would need to use a special drill that fits or can I use an alternative method to drill out the hole?
