prelude master cylinder

[fatboi]

Had a search on google and on here and can't find the answer I'm looking for.
Does anyone know if a BB1 prelude has a 1 inch master cylinder? If not, is it at least an upgrade over my stock ek4 one? I'm getting some 282mm calipers from my mates prelude, and I need to know if I need the master cylinder too.
Cheers.

I'm pretty sure that all cars with the 282 fronts have a 1 inch MC it should have 1" stamped somewhere too well an mb6 one does
