On the older monsters with the 20mm axle, they had 40mm mount Brembo 30/34 calipers. What is the difference between the 851/888 calipers that they continued on with the M900 (that used the same forks) and the brake calipers with the 40mm mount on the very early 748/916 ? Offset is the same I would think as would be brake discs. Or am I an idiot? (rhetorical question)
all gold ones are the same afaik. the black ones on the 851 maybe have 4 pistons all the same size from memory. i did kit my 89 calipers at one point, and i'm pretty sure they were all the same size. don't all the monsters have gold ones?
the 851/888 type are type P432D. 4x32mm

the later type on the Monster are type P3034 2x30 and 2x34
There were a couple of different series of the P3034.. 5165 and 6800. The difference is the casting and the bolt mount width, but they are functionally identical.
