do you use any particular brand of copper brake grease?I pulled my pads last weekend, and cleaned the heck out of everything, calipers etc.. The previous owner hadn't had them apart I don't believe. Put a little copper brake grease on the face of the pistons/back of the pads. Not a peep since. I seem to have to do this once every few years on anything with Brembos I feel like. My Thruxton R was the same and I fixed it the same way. Just pick up a T60torx bit and some blue loctite and be sure to re-torque everything and it is easily done in an afternoon.
