90-91 and 92-93 Master cylinder

What is the difference between the two? They have different part numbers but I thought the brake system was the same between the years…anyone know?

92/93 GSR has 1" master cylinder, which didn’t pop up again until the Type R. not sure about the non-vtec MC tho. sorry

im just trying to figure out if i can use a 92-93 MC on a 91…anyone know?

You can use a 92 93 master cylendar no problem you need to make a spacer on the push rod to make it work properly like the push i mean cause you cannot get enough adjustment with the push rod. Oh and one of the fittings is one size bigger and you need to reflare the tube but all said and done you will notice a very large difference in your braking. It seems like a lot of work but i would definatly recomend it.
