If the adhesive is truly made by 3M, I would trust it. Make sure you clean the surface really well before applying the adhesive. The better the prep work the better the adhesion will be. I'm guessing the most difficult place for one of those clamps to stay on would be the fork, since it constantly moved back and forth. Would these work with traditional mechanical brake housing too? The only issue I can think of is if the diameter of the mechanical brake housing is smaller than the hydraulic housing.
