I have One Lube which is also a silicone based lubricant. Just awesome. If you have access to the cable though you should use a true bike grease (any 'grease' will do actually) and rub it into the cable. Very, VERY thin coat of grease on the entire brake cable.
Also, grease your lever where they move and put grease onto any points that may cause friction along the braking path. Grease your U-Brake mounts, grease the spring inside your brakes, grease the connection point that rotates with the wire on your brakes.
Anything you can't grease, hit with Tri-Flow/One Lube.
