When compressing the little springs to remove the horseshoe clip/small clip, make sure you have a good grip on it or that little spring will go flying to the moon.
Take a bunch of pictures before disassembling so you get the stackup right on all the parts of that big bottom pin and take note of the position of the cam nut on the top of the shoes on the rear brakes. With new shoes, follow the directions in the manual but it might be helpful to see "what worked" before if you have trouble later.
