i have a speedfight 2 50cc liquid cooled x-race and the back brake wont work i checked pads and they are a couple of weeks old any way so they are fine and topped up brake fluid and checked line for leaks and its all fine but their is no pressure in the brake leaver so brake dont work. (my mate has exactly the same bike with exactly the same problem) what could be at fault? thanks for any suggestions.
just bleed the brake mate it just needs alot of pumping and realeasing the bleed nipple on the rear brake caliper when the brake is being held in it can take a while as they have micro bore braided brake lines as standard

sounds like air in the system try bleeding if not succesful then check the master cylinder(the 1 with the lever)if it not drawing air or leaking, or you might have a siezed caliper the item which push the brake pads against the disc.
