powdercoat wheel nightmare!

You could add your own and reuse them. As far as I know they are not torque to yield bolts. On one site, they joke that ALOC means Add Locker or Crash But buying new ones is not a bad thing.

Anyway the torque spec is:
Front Brake Caliper Mounting Bolts (4): 23 ft lbs
Rear Brake Caliper Bolt (1) : 16 ft lbs

Yes, they are torque-to-yield bolts. I researched this very thoroughly four years ago. Just do not want anyone to have incorrect information. That's why Honda want you to replace them.

Wolf, Not to start an argument, but can you provide any evidence of that? I ask as there are a number of ALOC bolts on the bike that are for mundane things. To me 16 and 23 ft. Lbs doesn’t seem like enough to really streach a bolt, but I’m not a mechanical engineer either.

Did you find out what ALOC means? On other boards they can’t decide if they are torque to yield or just have locker already applied.

I do agree that following the manual is prudent.

I do agree that following the manual is prudent.

When I first went to change the tires on my 2013, I found out about this. No other bike I'd had used this kind of bolt. So I researched it and learned that the bolt is a "stretch-to-torque" type and thus, Honda say it needs to be replaced every time.

I can't recall just where I got the information, but I got it, and I still have six of those bolts in my garage, unused. I laid in a supply.

The evidence is that Honda says to replace the bolt. If it just needed some thread lock, that would be specified as the procedure, not replacement.

But I do very clearly recall learning that this particular bolt was a stretch type and that's why it needed to be replaced every time. In fact, I compared the length of the used bolt with a new one, and sure enough, there was a noticeable difference, unlike what you'd find on a typical brake caliper bolt.

I found these bolts for $2.15 each online, so the price is not excessive. It's only necessary to remove on caliper (the left) to remove the front wheel. I think following Honda's instructions is the safe play here. These are your brakes, it's ten bucks for all four bolts.

Guys will pour thousands of dollars into cosmetic mods but try to skip a simple thing like this. I would not want to find out why Honda said replace 'em the hard way.

The other thing is, none of us are mechanical engineers, but Honda has some of the best. And they say use new bolts.

Well, that length difference is pretty informative. I think I’ll have to order some and lay in a supply too!

Good grief, almost 6,000 posts! Just noticed that. You got to be an old-timer around here.

I gave my service manual away and I thought about just giving those bolts to someone, but since I'm thinking on getting another CB1100, I'm gonna hang on to that and the cush drive inserts I still have new in the packaging.

Might need 'em sometime.

CORRECT = REPLACE as per Honda (did not know either)
In cars, same issue for cylinder head bolts = replace every time head is pulled off

I remember that the last time this question came up (probably a few years ago), somebody posted a pic of a used bolt alongside a new bolt. The difference was obvious. The used bolt was longer and noticeably thinner around the middle of the threads.

That's exactly what I recall.

Just to clarify, are the brake rotor bolts to be replaced everytime they’re removed? And the caliper bolts as well?

[Lord Popgun]

According to the service manual, yes. Replace.

However, the caliper pin bolts can be reused. Book says apply a locking agent to the threads.
