First off, if I posted this in the wrong section. sorry please move it accordingly.
Second..
I have been playing around with a 82 k10 making it my new camping/wood hauler. I recently swapped out the rear 12bolt for a 14bolt ff out of a 1976 k20. All went very smooth with the exception that since I have done the swap I have not been able to get my brake pressure back. I have installed new rear hard lines, new brake cylinders and now a new master since the old one looked pretty crusty. It has been bled out multiple times now and still my foots going to the floor.
Anyone have any suggestions? I have looked for leaks and there is nothing.. everything is dry and I am not losing fluid.
Any help much appreciated in advance!
