I'm informed on the OzDat forum they're R31 Skyline...makes sense since it's bolt spacing matches older 240k struts.
Am I correct in describing the Sumitomo as double piston i.e. single opposed one each side and is this providing better braking that the R31 with a single piston?

Subject: curious to know what these calipers are from?


Hi all, had these calipers sitting in my shed for a while and I want to fit them to 240k struts with 253mm disc - is it a bolt up job, do I have to be concerned about pad area and disc size? I don't know what these brakes are, they have know name on them just numbers cast into them, bolt spacing is 3.5" which matches my 240k struts (at least that's what I recall 240k struts as being). I don't know my master cyl size, buried under the fj20 plenum in my 1600 but has a dual remote fill setup like (Nissan Urvan?) and is running the 240 single pot Sumitomo calipers now - stopping is no problem, but heat built-up looks to far better handled by these old school alloys I have compared to Sumitomos.
