A radially mounted caliper is stiffer, and is better at maintaining alignment with the rotor. This means the pads stay in alignment better, making better contact with the rotor and exerting less lateral force on the rotor while generating less heat for a given pad pressure.
With traditional caliper mount points on the trailing end of the caliper, pad pressure at the leading edge of the caliper has considerable leverage to misalign the caliper in relation to the rotor. Radial mounting takes care of that. Putting a mount at both the leading and trailing end of the caliper, leverage at the leading edge of the pads is reduced to a level that it becomes insignificant.

RE: Explain: Radial Brakes
I'm speaking of in terms of design. For example, my F4i has standard mount brakes, but the RR has radial. The new '07 RR added a radial master cylinder. I understand the goal is better brake feel and stopping power, I just want to know how to be able to tell the difference by sight and understand a little on how they operate.
