I am a municipal tech and we have about 6 IH workstars running eaton es style brake shoes mounted on Rockwell drives and steer axles (meritor also makes a brake shoe that works on eaton es platform). My question refers to the 16.5" x 6" that is used on the steer axles. This design uses a heavy return spring on each shoe that hooks to the pin in the roller end of the shoe and hooks to what is referred to as the horse collar ring that is located between the s-cam tube and the s-cam. My question is has any one out there developed a trick to easily install both springs. I usually end up using small pry bars and screwdrivers but it is anything but efficient. I have searched online for any tools available but all I find is the tool used to install the anchor springs which we have. I know of the chain trick used on meritor Q and Qplus shoes to attach the main return spring and wonder if the same idea would work for this style. If it does you would have to do it twice once to hook the upper shoe spring then again to hook the lower. Have not tried it yet as I just actually learned the chain trick a couple months ago. Below is a image of the hardware kit used on this brake set up. Any tips is appreciated.

Sounds like you are trying to install the springs after setting the rollers in place?? If so install the rollers AFTER you install the springs, that way you are not trying to stretch the springs as far. You can carefully pry each shoe out enough to set the roller in place between the shoe and S-Cam. Different spring setup but same function.

If you have a tuning fork, slip it up on the shoe here and pry the bottom shoe down and install the roller… just make sure you do the top shoe first…
