Replying to Bending Binding Brakes

I just got a pair of Dynastar px12s which have an 80 mm brake width, and need to bend them to get them to fit my 89 mm double times. Alas, I have a whole slew of noob like questions as I haven't had this problem before.

1) will my shop bend the brakes for me when I get them mounted? If so, all following questions are irrelevant.

2) Does anyone have good ways to bend brakes (preferably without dismantling the bindings)?

3) Could I just bend them by hand? I've tried and it hasn't been working so great, but I'm also really worried about snapping something in the bindings.



thanks in advance and k+ for any help. (and inb4 "searchbar n00b" yes I did searchbar and no I didn't find anything helpful.
