Thanks, Guy's. I'll just keep it at a sensible speed and on paved roads to be safe. It's interesting what 180 said about the different surface area of the brake cylinders (I presume the brake calipers). Mine are stock XF calipers and the pads were from Needswings as a set for front and rear. They are ceramics and seem to be working as they should. The rotors are new also. I was hoping there was a way to make the rear brakes do just a little more work than it seems like they are doing. I'll just have to live with it and hope the electronic "stuff" keeps doing what it's supposed to do.
