Yes, as you think, it doesn't affect the wear as that is only the hydraulic force clamping it. And also same forces as the modern ""sliding " single piston type. It is a bit cock-eyed though (in purist engineering principles) as they've started with a swing geometry so the pads will ultimately wear in a taper, then felt the need to give some sort of assistance plus limit to the assembly. Compared to the straight up design within the engine it does appear to be an odd compromise.

Does anyone know if the two "cross-head" screw driver shanks in the OEM tool kit are JIS-friendly?I'd imagine they are BUT they aren't exactly case hardened so will break eventually, plus the handle is just not up to the job. The ones in the link are magnetic tipped as well, which helps a great deal in getting screws back into confined areas, especially carbs and such.

You have to be reallllly careful with those as they will snap off. Think the common advice on here is to heat them first, but they can be very tricky.Looks like it was mainly stuck on pad corrosion. Rain and salted roads make easy work to get that going, if you're not using in winter then obviously less likely. Interestingly, the original manual for the 750 says about the caliper, to use "silicon sealing grease" all around those pads and the interface with the piston. Presumably they are trying to exclude water as that stuff really resists any ingress. It specifically states "Do not use molybdenum grease, known as brake grease".
Yeah it's silicon, they use that stuff to make oven mitts out of these days.
Personaly i would replace that piston, they are not expensive and you only got one neck

Just did a quick "phenolic" search - the name Kevin Hunter appears a couple of times. Anyone with experience on this OEM/phenolic/stainless question care to chime in?EDIT: Kevin Hunter hasn't posted on that forum in many years...
