brakes not working right

If the M/C pushrod was removed/replaced, the M/C pushrod pivot bolt can be installed/tightened in a manner that causes it to bind, giving a funny " feel", restricting pedal return, and by not returning all the way will affect the M/C operation.
Try loosening the pivot bolt 1/2 turn to see if prob goes away.
If it does, fix the issue with the bolt.
Good luck
