bleeding brakes

When you mean not bleed do you mean not fluid comes out or that air keeps coming out of the bleeder? If the fluid is not coming out I would crack the line loose at the caliper and then push on the pedal to see of the caliper is getting pressure and it is a bleeder issue. If no pressure is observed I would expect the brake flex hose from the frame to the caliper. Here is a video and guide below to help you bleed the brake system correctly.
