Bleed the brakes again.
this time start with the SHORTEST line (most likely the LHfront)
Then the next shortest and so on till you get to the longest and have given the MC all the advantage you can.
Otherwise your second hand MC may also be airlocked or bad.

thanks for the reply problem resolved bled the 3 outlets on the ms on a loop (back into the ms)
cleared all the air from that, then bled the system normally with clean fluid
thanks again for your interest

Does your truck have ABS? Give it a good roadtest with a few emergency stops then re-bleed the system. Sometimes air gets stuck in the ABS pump.
Personally when I am bleeding brakes I will get an assistant to pump the pedal vigorously then hold it on. I will then slacken the bleed screw release the air/fluid. Then I tighten the screw before telling the assistant to release and re-apply the brakes.
People think this is the long way to bleed the brakes but you won't need to re-bleed the system afterwards so it works out faster!
