The front brakes on my bike are squealing and I've read that the problem is the pads need to be toed-in. Several sites recommend using a dime or penny behind the rear of the pad while you tighten the bolt to help with it however the rear of my pads are behind the fork and there's no room to get my fingers in there.

Any thoughts on how I might accomplish this? So far it's been an exercise in frustration. Thanks in advance.
