Following on from my previous thread "what are these mounts for", I thought I'd make a more specific thread regarding them!
So I have these mounts on my bike, there is one on each side of the seatstay (they are the screws below the mudguard and above the reflective sticker). I was wondering if they would allow me to mount a rear brake. The rim of the wheel is below the screw.

If they are intended to screw cantilever posts into then it is a very odd frame. Canti posts normally mount up on the back/upper side of the seat stays. Also they are generally either welded on or there's a welded on base to accept a screw in canti post. So these screws are in a very odd spot. They may be mount points for brakes but if so it's a style of brake that I'm not familiar with. Certainly it is not for cantilever or V brakes. Perhaps it's intended for some sort of center pull U brake. But those normally attach to posts or mounts that are higher than the rim. So all in all this one is a mystery to me.
What brakes does your rear wheel use currently? Since there's none showing I'm guessing that it's either a hub coaster brake or a low mounted center pull. I'm guessing coaster brake since the rim looks oddly like a disc brake or coaster brake style rim. The face that the rim brakes would rub on looks VERY small unless your'e running a very fat tire. So adapting a rim brake onto this bike may well require that you buy a new wheel to go with it. Can you measure the width of the face where the pads would run and let us know? From that we'll be able to tell you if rim brakes are an option with this rim.

I suspect they may be placed there to mount a Ring Lock onto. the lock remains on the frame,
and you ride with the key in the lock, then to immobilize the rear wheel,
close the hasp of the lock around the wheel, and remove the key.
no roll off thefts. very convenient.
I have an AXA Defender ring lock and a 1.4M long chain that adds the ability to lock up the front wheel
and put the chain around something solid, with a pin that fits in the other side from the lock Key. catches in a receiving socket.
Abus offers a similar ring lock setup.
My NL built Koga Miyata included a ring lock , when manufactured ..

Disc brakes at the moment. Unfortunately that ring lock explanation sounds pretty plausible :( never mind! Am converting to fixed gear so have to forego the disc brake therefore was wondering if I could put a different brake on the bike! Oh well, not to worry.
@BCRider, I have just built a fixed wheel that has a braking surface, so that is not an issue. Thanks though.
Thanks for the info.
