The bike is a 1988 R100 RT, which has the Brembo brake calipers. I have two questions.
1.) I had ordered new brake pin kits from an independent retailer (not a dealer), which they indicated to be the correct replacement part. Although the pins provided were from Brembo, they are slightly different. When I went to drive the pin in to fully seat the pin, it went in too far. Upon examination, there is a shoulder on the newer pins that is shorter than the shoulder on the pins they replace (see photo). The only difference is the length of the shoulder. While these are Brembo replacements, they do not appear to be the correct replacement pins on my calipers. The image of the pins from Max BMW’s website show the pins with the longer shoulder, like the pins I have. It's not too hard to center the pin in the caliper, but with the older ones when they were driven all the way in, they were centered. Should I leave them be or replace with the proper pins?
2.) Motobins has aftermarket stainless steel replacement pin kits. My knowledge and experience with stainless steel hardware is very limited. I've read and experienced stainless steel nuts and bolts galling, but I'm wondering about the application here. Does stainless steel seem like a good or bad option here?
