Never put thread locker on those bolts! They are hard enough to get loose without thread locker on them.

I just wished that I flushed it. Maybe it's not a big deal at all and something I'll do next time.

Only 8-9 lbs of torque? I'm no mechanical engineer, but I may take argument with Honda on that one. I've read that threadlocker shouldn't be used either.

But would you trust things at only 8-9 lbs? If those sliders come loose...then....hmm..

 Maybe I should back off my 40lbs...it didn't feel like I was giving it THAT much pressure.

I rinsed my fork tubes with SeaFoam Engine Treatment (100% petroleum distillates):  I added 2-3 oz. of SeaFoam to the old fluid in each tube, prior to draining, then I pumped them up/down 5-10 times, to circulate it through the upper/lower portions, to mix it thoroughly, and to allow it to dissolve any deposits within the tube assemblies; after that, I drained it, and added fresh ATF fluid.

If you are concerned about it, re-do it.  ATF fluid is cheap, you can be certain it is completely flushed, and you will be able to re-torque the screws to proper levels.  Cheers!

Even if the bolts did come loose the worst that would happen is that you would lose all the fork oil. Unless maybe you were into riding wheelies. Then you had better be into unicycles.

Completed this task. After compressing the piston with a c-clamp so that I could get the rotor back on, I somehow injected some air into the system by doing this (this didn't happen when I did this before).

Brakes were spongey and stopping power was weak, so I quickly turned the bike around into the garage.

Bled the brake fluid, and I also followed the manual on adjusting the caliper, which is basically tightening the flathead screw until the rotor rubs the pad, and then backing off a little bit.

All is great now. The forks are nice and wet, and the fluid hasn't seeped out over the dust cap yet. I'm always looking for that since I'm use to that happening.

I'll probably use some heavier weight oil for the forks in the future. While ATF isn't "bad", I would prefer something with a little more density to stiffen it up some more. ATF is about 7 weight from what I've been reading. I think 9-12 would probably be about right.

These are incredibly concise instructions. I replaced mine this weekend exactly as prescribed. It's great having the progressives work the way their supposed to again. Thanks, TOOLS.
