I did some work on my Spyder( valve adj. check, belt tension etc.) After brakes warmed up they squeaked like crazy at the rear. Finally discovered that the combination of moving things around put tension on the e-brake cable. The cable was pulling the rear caliper crooked and when I gave the sheath some slack...my squeak went away. Might be something for others to look for. I hope my post makes sense?!:sour:
