I had the drums and rotors on my RR turned down and now they are only .001-.002" over the minimum thickness numbers cast into them. Is it a good idea to use them if they are getting this thin even though they are still within spec? Right now I'm having trouble getting the brake pedal (which is already close to the floor before pressing it down - see my other post here) to activate the brakes without having to press it all the way down to the floor, and I'm wondering if the thinness of the drums and rotors is adding to this problem. I might need to do some more adjusting on my rear shoes to try to remedy this, but you can only move them out so far and then you run out of adjustment. Also, it seems like you are limited in how far the pistons in the calipers can move to push the brake pads out to contact the thinner rotors on the front brakes.
