Need I the "mushroom" on the piston of a Honda Cb750 K6 Caliper ?

Hi Guys,

As the topic say's......
What do you think, will it fit ?
I will use one, or two ( when I get the piston out of the second ) for a dual disk conversion.

According to the drawings the arm lever etc are different, but I also have these.
Don't think the fork legs, and wheel hubs are different, right ?
I think at least the brake disk are good to fit all types.

Ok this is what I have now mounted, original K6:

These are the ( I think ) K7 types there Tokico 3 on one and Tokico 4 on the other, for the rest they are similar.

The biggest visual differences are where the bleeder, and pressure mounting hole are, and the fact that with the K6 the bolts mount from the other side.

Re: Will a CB750 K7 Caliper fit a K6 ?

My problem was solved, got a correct type caliper now.

But maybe the question still can be solved for fellow DTT'ers with the same problem

Re: Will a CB750 K7 Caliper fit a K6 ?

Been messing with the double front brake yesterday evening.
Just need to make bolts the corret lenght and do some shaving on the speedo pickup.

While assembling the new caliper seal and put back in the piston, I noticed I am missing the "mushroom" thing which on my other caliper fits in the piston.
Do I need to have this ? or will the piston push the block just as good without ?
Will i get in trouble due to missing some inches, and pop the piston out eventually ?

EDIT

Found the part
