Brake disc mounting bolts

[Miztaziggy]

The manual recommends replacing these every time they're undone / redone.

I must had had mine out and back in 10 times in last 3 months when changing wheels. I never locktite them or use torque wrench, and haven't had any issues, but now I've read the note in the manual, I'm thinking I should change them, or at least locktite them.

Anyone else recommend changing them or something, or do they say to change them just to save rounding off the Allen key hole?

I would imagin it's all to due with the elements taking effects on the Allen key heads. They may stretch a little but should be much as I don't think there done up very tight?

If the manual has a measurement for the thread then measure it against that? Failing that ask to speak to a tech at suzuki. They may surprise you with what they say.

I have had many bikes and have never changed them,never had an issue neither but there again i don't take notice of sell by dates.

They tell you to replace them because of the Lawyers.

As for wear on the bolt, here in sunny Ca we don't have the corrosion issues that you guys have which makes bit last much longer.
With that, I am still using the caliper bolts that came on the bike when I purchased it way back in 9\97.

In that time I have run 2 different front ends.
2 different sets of calipers
More front pads than I want to admit to going through and the calipers being pulled more times than I could possible remember.

No rounding of the Allen hex, no bolt stretch.
Though you do need to put your own lock-tite, which IMHO is way they tell you to replace them as they don't trust you to do this step correctly.

So I believe I have done a pretty thorough test of the bolts and can confidently say that you can reuse the caliper bolts with no worries.

I have reused mine and about a year ago I pulled the thread on one, so I heli coiled it and thread locked and seems fine so far

I've always re-used mine with no issues, I wonder if they advise to change them, because they'll earn money out of it!!!!!!
just a theory....

Its a bolt. I reckon 3 would be strong enough to stop you on one disc. I think the heads could snap off several with no issues. the disc is mounted on a boss on the wheel and there is no lateral force involved on the disc, pure shearing force on the bolt, no twisting or bending on it.

I got the wrong end of this thread
or is that the wrong part
I thought we where talking about the two calliper mounting bolts
and then I read the last post and realised

Hard steel bolt vs soft aluminium wheel? Don't think bolt stretch/stress is the reason for Honda's recommendations. The comment about lawyer issues is probably on the money, but also the OEM bolts probably have a pre-coated threadlock compound on them that Honda think should not be relied upon for re-use.
