Installed these on my lunch break.
I replaced the sleeves that the pads slide on because the old sleeves had a notch wore in them from age. Sleeves from the local farm supply were about 3/8" too long so I ground them off but I ended up leaving them about 3/32" longer than the originals.
My theory was that the original pads had a tendency to drag a bit and adding a bit more spread to the caliper would help this. So far it seems to be working because I have a little air space between both pads and the rotor.
This may be a viable tweak to this e-brake setup.
A little adjustment to the rod and it holds like the drivetrain is welded and releases clean.
