Pumping the brake pads to run closer to the rotor will provide less lever travel. The earliest disc-brake systems on mountain bikes could suck air into the hoses if the bike was turned upside down. However, the advantages of disc brakes lie not in the size of the rotor, but how efficiently force is transferred from the lever to the braking surface. Automotive disc brake cleaners can often be problematic. Generally speaking, high-end resin pads will often use aluminium backing plates, while the metallic versions will use titanium backing plate.
