W126 300SDL Sticky Caliper Brake Job

I want to run through the to do list with you guys for my own future reference (and to see if you all could point out a missing procedure I may have overlooked). But I reckon these are the things that need to be done to get rid of a sticky caliper with a lip on the rotor: replace pads and rotors, clean and relubricate the caliper pins, clean out cylinder bore of any debris and rust, apply dot 4 fluid to cylinder bore and the brake piston itself...then re install, apply anti seize in appropriate areas, replace brake hose (It's brittle), bleed brakes...and finally, a test drive to see if it stops sticking.


I have Bendix calipers, but I actually noticed that the pins are too short for the calipers so now I'm interested in finding some actual Bendix pins instead. If the pins are too short will that cause problems for the caliper?

Moreover, I have been searching around and can't find any Bendix pins other than a guy from Wales in the U.K....who does not ship to the states. Where can I get some pins?
I looked up this diagram of the brakes and was also wondering if the part labeled 26, is the pin I need? It's referred to as a 'dowel pin', part # 0009917360.
Finally, how can I push out the pistons without pressurized air?

Don't forget to grease the screw and threads on the spring compressor.
