WTF can I do? Rear brake mount has no thread
Wow. That was fast. Thanks.
Disc IS mount. Slightly oversized holes like what Ton says. Sorry – Im a noob.
Yes, the threads are in the adaptor. However when I attach it and tighten there is still a bit of wobble – I need another 1/2 turn. I thought the mount needed facing but when I hold the mount against the frame without bolts it sits perfectly flush
edit: there is a bit of thread in there but the hole is slightly OS. I'll try a dab of loctite or similar which will probably sort itPosted 7 years ago

There'll be something stopping it sitting flush then – sounds like it's on the outboard side of the mount where the bolt heads sit, not the inboard. Probably a blob of paint. Quick rub with a file, or even quicker, nip the bolts up so tight the paint gets crushed off.Posted 7 years agoIAMember
Eh can I suggest caution with the rest of your bike assembly? Bolting brakes on is one of the more trivial tasks, so I worry about the rest of it! If you can't bolt them on, can you set them up correctly? Parktool.com has great advice if you need it.
(I'm not saying don't build it, just to be careful, take your time and be sure you're getting it right)Posted 7 years agoThree_FishMember

There isn't any thread. Calipers and adaptors are threaded, so the frame doesn't need to be. In fact, threading calipers/adaptors means that he frame can't be threaded – it wouldn't be possible to align the threads and one set would invariably be destroyed. The holes in the frame are just plain old holes, slightly larger than 6mm. Threadlock is a complete waste of time/threadlock.
Worst-case scenario is that the frame mounts are not fitted straight, so the threads of the bolts are marking the interior of the hole when you tighten everything up. I think that your best course of action would be to let a bicycle mechanic take a look for you.Posted 7 years ago
