After further inspection i found the shaft had to much play allowing the arm to move freely and shoes to rattle.
I removed the e-brake shaft, I then purchased and installed a Hillman rubber grommet 3/8x15/16x9/16x5/8 through the floorboard. Reinserted the shaft through the grommet I/D and connected to the arm. No more play in the shaft and arm and the rattles went away.
