Topic: help me figure out this caliper

[theslayedsaint]

ok heres some photos of a caliper i have that i can't figure out whats its off of. it came out a " CB750 1978 F" but the piston is bigger then the front brake ones.

Possible caliper from the rear disk?  Did 78 Fs had a rear disk?

GL1000 or GL1100 had very similar calipers but larger pistons.
They use the same brackets to mount to the legs.

I have heard of guys "upgrading" to the larger piston calipers.

 One of the fronts on 77/78 F is the same as the rear caliper..

I know the pads are the same, not sure about pistons now.

ok.. I'm just a little lost of what the hell it could be. it looks just like the front calipers nothing like a goldwing. anyone know if they made the cylinders bigger in latter years? or could you bore it out... that seems like a wast of money ahah

78 GL.
Not the latter twin piston ones.
That's what I bet it is.

 I thought F's and late K's had the center bleeder caliper with a bigger piston. ?

I think i found it.. seems to be off a CB900 and I think some GL. we shall see if its the right size it seems like it should be close.
