Yes, it is a press fit. You will destroy the old one getting it out. I think Yamiya do the caliper and spacers for the 750 conversion
Hi Sprinta,I am in the process of gathering the parts to add a right disc to my 750 K4. A second hand Caliper and arm cost me £50 and a disc £20. The Yamiya Caliper and arm is £350 ish plus shipping and duties and looks like K0/1 type to me.There is a olive of some type in the Caliper in the pipe location. I have removed it by threading it and pulling it out with a screw. I am planning to make brake pipe with a bubble flare and a long M10 tube nut. Hopefully this will seal.The other issue I can see is securing the steel brake pipe to flexible to the mudguard. The left side has a correctly bent wire welded to the mudguard. Not sure yet what to do for the right side. Maybe a K0/1 type bracket can be adapted.The conversion is far from straight forward. Where are you at with the job?Cheers,Kevin
The seat is the same as the bleed valve side. As I mentioned I am hoping that a bubble flare will seal without the need for the unobtainium olive.
