easy fix for caliper upgrade.

I didnt think they'd be long enough as the sleeve wouldn't go all the way inside the holes where the calipers aline onthe fork stantions. These are bolts used on the front discs? Strength in numbers comes to mind. I wouldn't trust them in the calipers what with the forces that are going on down there.

Of all areas to neglect basic good engineering principles ..The brakes are not the place.....As I said its far more complex than " they work on a 1000" there are both shear force and tension forces to consider. Fatigue...creep etc......Add to that that some caliper bolts are meant to be replaced every time the caliper comes off ( torque once bolts) . just like conrod bolts. Unless you know why a particular bolt is in a particular application, I would not compare the two situations. At least use the highest tensile strength bolt you can for that size and dont shear load the thread area. Anyway take my advice or not. But as an engineer I would never suggest using those whithout a lot more data. take it or leave it......cheers

not doubting your engineering skills at all tk400. and sometimes things are a little over engineered, the back brake of the zxr springs to mind.
i used spacers and bolts on my calipers and never once had a problem, and i took mine on and off several times to change wheels etc.
i agree with you in a lot of what you say, but i took my bike out on the 'suck it and see' bases and it worked. admitedly i kept looking down for the first few laps to make sure the calipers weren't hanging off!! but it worked and the same bolts are still in the bike now 3 years later.
like i say not doubting anyones profesional abilities but i genuinly think that andyvp has stumbled onto a good thing there.

fair enough, Im runnin outa breath anyway......LOL

The bolts will work, I've used them to mount gixxer calipers. Just a bit of a pain to drill for safety wire.

I fitted the 6 pots to the wifes zzr600....easy to drill and tap the 10mm thread. Some High tensile bolts from the bolt store. Sorted.
I think the 8mm v 10mm is a no brainer.....Just imagine...at the time you REALLY need ya brakes to work well.....

right this easy fix wasnt so easy! the calipers i used were off a 900 fireblade and bolt on fine with the bolts previously mentioned, but the 310mm L model discs are too big! they catch the back of the caliper! gutted i was!

anyway a set of 300mm H model discs on L model forks with fireblade calipers and suki bandit bolts should fit

just need a disc for the left side now to find out...
