On my 2005 C'dale Bad Boy, the cantilever brake pads are almost impossible to replace. These are the long pads that slide in from the back, then youre supposed to lock them in w/a pin. But it's hard to get them in all the way. I used WD40 as a lube, and it worked great; had no apparent effect after a ride. Will WD40 dentegrate the pad? How bout chain lube, grease, vaseline,???

I'd try some liquid dish soap, there's just something wrong with using a lube like that on brake pads.

I've put those pads on Cannondales before with the pin. You can use a vise to press them in or a long handled pliers.

Maybe Hair spray? I've used it to slip grips on, it evaporates , and then is sticky..

KY. Works well for things like this. Once the pad is on, you just rinse with water and you're done. I wouldn't use any petroleum-based materials, but you will figure out what the residue does sooner or later.

I use a drop of white lightening, evaporates fast, any wax residue will just flake off without messing up the braking surfaces.

hairspray best, as is not water soluble or lubricant - vice good too- your issue normal for lots of brands and types
