BR-6600 toe-in adjustment
I'm just installing a new BR-6600 front caliper brake, and I'm definitely in need of some toeing-in.
The instruction sheet and the marketing blurbs talk about being able to adjust toe-in using the brakepad mounts, but they neglect to provide instructions how.
The one thing that seems clear upon trolling the repair sites/advice is that the old trick of adjusting toe-in by violently twisting the arm is no longer acceptable. How true is that really?
For the sake of Google-searchers who are similarly mystified, I'll post the resolution.
With your BR-6600, pull the pad off the calipers. Then screw the fixing bolt back into the fixing nut, just a turn or two, not all the way. Then wiggle. Then tighten it all the way. Then try to wiggle, and it won't.
That's right... when it's loose, the fixing bolt is designed with play in it, so you can adjust toe-in and other things. Once you tighten it back down, it's fixed in the position it held while being tightened.
Hope this helps!
