rear brake lockup

[dunny29er]

ok so my dhz popped its rear brake line coz it got so hot coz it locked up anyway i got a new one and bleed the brake completely.

I adjusted the lever so its all perfect. The brakes work perfect but after 10 mins into the ride the brakes lock up again??

The disk isn't warped (most have a little bend in it) making sure the piston is clean and well greased
