Brake caliper bolt lengths - longer calliper bolts?

ive got this problem to!
if any of those long bolts be offered around are still available i would happily take them off anyones hands! cheers

Cernan: I drilleded mine out in the end. It's not a big job really since there's already a pilot hole in effect.

drill it. piece of piss, takes literally about 15 seconds then you can put a decent modern caliper on. you would have to be a retard to get it wrong.

which is precisely why i shouldnt try it!
i get far to excited when i am working on bikes and as a result lose concentration and seriously fuck stuff up maybe 50% of the time.
for example (i shouldnt admit this probably) on getting new pedals i flipped my frame over to fit them rather than work on it in the roof hooks and promptly destroyed the thread in my non drive crank trying to fit the wrong pedal to it.

Or you could just source a dual pivot caliper with a longer bolt on it with conventional nut on the back. I have one of the these on my converted Bianchi and it stops the bike fine. LBS at £10 a go.

anyone want to gang up and do some gang drilling? i have the same problem and would like to solve it.

Sorry for the bump, but does anyone know where I can buy a pair of recessed hex caliper mounting bolts?

Pair of calipers I purchased from ebay appear to be lacking them :(

I know this is an old thread, but I have the same prob... anyone with spare long bolts knocking about?

*bumps for both of us...

I have an NOS bmx caliper with a long bolt, ideal if you have super-long drop requirements (it's more than the usual 57mm longdrop). It's a freestyle cable route, so cable goes down below the caliper, threads through upwards and bolts on at the top. £10? Brand new, fitted and removed (once I realised the blocks would grab my spokes!).

did any one buy that brake?

I have a rear shimano caliper from my old bike and want to use it on the front of my new build - from UTFS i understand all i need is a longer "sunken retaining bolt" like this;

My question is, which length do i need? I'm assuming the longest 18mm one? I think the one i have at the moment is possibly 10mm.

Cheers.

The longest one.
(You could always measure it?)

Remember to turn the pads around and re-toe them in.

ah bingo! i didn't know you could get these. i had to put 2mm of spacers infront of fork crown as brake hit the headset and so the brake only has few turns on the bolt, bit worried its one day going to thread and fly off under heavy braking - problem solved!

I bought a load of brake parts from here a while ago to somehow cobble together a working front brake. So far I've gotten nowhere...

I need to remove the center bolt nut from one, to use it on another, but it doesn't seem to budge at all. I've removed the little screw that the're working on here

to then remove the bigger bolt, that they work on here

but the bolt itself doesn't move even a fraction. Is this even possible?

bump

When i took my Tektro's apart (although they look similar).....there was a grub screw holding the main bolt and it too a fair bit of leverage to start it moving as the bolt had been Loctite'd in (the Blue Threadlock stuff)
Hope this is of some help.

cool cheers, that's what i thought. Gonna give it another go but seems like a need a vice tbh

hi all,

ive got a campag mirage front calliper (recessed nut) and im trying to fit it into some Columbus aero tusk forks. I cant get the bolt and nut to meet through the fork

the fork hole is wide enough at the back for a recessed nut, but the nut I have is too long so wont sit flush as it keeps banging into the front of the fork from the inside.

ive tried fitting another brake with a slightly longer bolt and shorter nut and these also wont meet. I've also tried a few combinations.

does anyone know of a brake calliper with an exceptionally long bolt or any other fix?

cheers

You need a longer bolt.

You need a longer bolt.

^This

Most brakes, when new, come with a variety of lengths of bolts for just this situation. I assume yours is second hand? Good cycling shops will have spares and will give you one for free.

yeah, the calliper is second hand. At risk of seeming an idiot by bolt you do mean the bolt holding the actual brake together?
is it a pain to take apart?

thanks for the reply guys

no, the other bit

I'm a bit confused as to whether the nut you have is too long or too short.

Either way, they are commonly available in a variety of lengths, which will sort you out.

Why not try the shorter nut you have, with the Mirage calliper?
