Any suggestions on how to stop brake pad squeeling on my Eagle Claw 2 brake pads. They were fine until recently but now squeel loudly when hard braking which is very annoying not to mention embarassing when you sound like and old dump truck coming to a stop. The pads are less than a year old and still have lots of pad left. I have cantilever style brakes and it was suggested to adjust the toe in but I don't see a way to adjust it without physically bending the brake arm post connected to the frame which is rather scary for fear it will crack.
