P brakes dash light wont go off!!!!!

I just installed a 3 inch lift and the first probem i get is that my parking brake lights in the dash wont go out. Anyone have this problem? It happened right after the lift. I tried to loosen tension in the line but it doesn't do anything. even though the P brake light in the dash is still on there is no engagment in the rear brakes. Don't know what it could be. Please help. thanks

Whar year and did you remove any brakelines(hyd)???

fixed it...

Ya fixed it tonight. I bled the rear brakes and in the process let the resivoir empty and air into the front brakes. Bled front and back today and light went away.
