I've fitted a set of the bargain Fox 36 forks (which are great!) but when fitting the caliper I noticed I no longer need the 20mm caliper spacer and now my caliper bolts are too long.
I have SRAM brakes and the have conical washers on top of the caliper and between the head of the caliper bolts, are they needed?
I've managed to find some old Shimano caliper bolts and I think they will be too short if I use the spacers.
If I need to get shorter caliper bolts would something like this be okay?:
The cup n cone washers are only needed for the adapters with two unthreaded holes, caliper straight to post mount just needs 20mm m6 bolts and some decent washers around 12mm OD. Those Toolstation ones might be a bit rough n ready but should be okay, Hopes tapered head bolts are quite though.
I would try SJS (St John Street) for decent bolts.
Holt or Allen might also do them in marine grade stainless steel. Available from a chandlers if you're near a boaty place.
Cut down the old screws if there's sufficient thread? Ask at your LBS? What length are you after, is it 20mm as in the Toolstation link? I have loads of socket screws in various lengths, let me know size and I'll post your way if you want.
Thanks for all your advice, I did contact my local bike shop but they only had the same bolts I managed to find in my nuts a bolts draw!
That's very good of you to offer Ambrose, thank you. I've had a better idea tho.......I already have the 20mm spacer and longer bolts to match so it's an ideal opportunity to upgrade the rotor to 200mm instead :).
Go big or go home 🙂
Sorted!
Sounds sensible on 36's!
FWIW I've been using Toolstation stainless bolts in all my brakes for years. Started with a big bag because I needed a couple, and swapped all the rest because they look a bit neater than plan black bolts.
Using them elsewhere could be a bit dicey, I tend to assume that any bolt that wasn't stainless to begin with was probably high tensile or chromoly and shouldn't be swapped (e.g. stems with tiny little bolts, brake rotors, etc).
Long M6 grubscrew thread locked into the fork then use nylok nuts or nordlok washers. I'm not a fan of using setscrews/bolts into magnesium unless there are thread inserts. I'd rather use a long grub screw/engineers stud that stays in the fork with the nuts being removable.
^ for the same reason I like brake adaptors that bolt to the fork/frame and use a second set of bolts to mount the caliper.
