I have bought these of a friend today they were originally of a 2wd saff . My mate told me they are godspeed calipers bells and rotors .
After a bit of research on the net I can't find any thing like these. They are probably quiet an old caliper now .
I would like to get new pads also I want to make new bells and brackets to suit my 4x4.

I've taken photos of them and you can see the G S cast into them . Oh they ate 325mm too.

If anyone can give me any info on these or help let us know cheers

 

99.9% sure they are VOLVO calipers, normally used with TWO brake pipes, as each pair of opposite pistons fed seperately, has one channel been blocked off next to the existing brake pipe ?, or maybe volvo didn't use all four in actuation on all cars.
The GS is NOT GS but SG, nothing to do with godspeed.
The discs are cut down discs from a solid one piece that has had the bell cut off that's all.
