Brake system failure on a kx 125

Had a crash a while ago where I tank slapered myself into a fence and broke my shoulder. Just so happens that when the front brake lever hit the fence it depressed it so hard that before breaking it blew out the brake line/caliper seals. problem is I can't get any pressure whatsoever to try and see where its leaking from so I can order parts. If anyone has any ideas it would be greatly appreciated
