Kelsey Hayes Disc Brakes

Hi Everyone!!
I wanted to let you know that I have that Caliper setup on my Lull Telehandler. It is used as a Machine Brake, and is used to "Brake" the Machine's DriveShaft. I am currently looking for Pads and Caliper Seals if anyone out there has any information? Lull/JLG has no info on them!
Thanks !!
