so how much this run you and what exactly do you need....the cup, a new M/C right?

 

And the brake lever for a 929 or 954 (those might be interchangeable) since the f4i brake lever will not fit

 

Gonna need a 929/954 master cylinder, cup assembly, and brake lever off a 929/954. Also a 5-8mm longer bolt for mounting the reservoir cup on the collar on the m/c assembly. My total cost was $70.

FYI, to rebuild the assembly is only $30, so even if you get a really used m/c you can get the kit and make it like new.

 

i'm finishing to mount it all today or tomorrow. guys primed the lever, i will paint it black to match and mount altogether. i'm using the whole m/c assy together with the stock bracket. the reservoir will be much higher than pictured, i will look what i can do with it to mount it lower. so far, no clearance issues with the whole assembly .

 

Post some pics, I wanna see how yours turns out!

 

so the stock f4i line and bolt went into the master just fine? i just got some galfer lines and i dont know if other master cyclinders use different diameter bolts/banjos than the f4i....

 

axsys, they 're all the same, well maybe some not, but it will fit for sure. to install the mс from the 929/954
you should have:
-m/c
-brake lever(it's longer and less bent than f4i's and they aren't compatible)
-the 929 bracket with reservoir or any other radial reservoir.

btw, some interesting stuff. while interchanging the calipers, i found that the brake pads for 954 are different. they at least differ by having the perforated metal sheet from the back(i would assume it could do a bit of additional cooling) and maybe compound. i'm thinking it could be beneficial for braking. have an idea, that 954 pads (maybe aftermarket ones) would be more grabby and cooler running that similar f4i stock.
what do you think, guys?

 

Do you mean the 954 stock pads have the preforated metal sheet on the back of them? I just installed EBC HH pads for my f4i and they had that on them. I think the calipers/pads are interchangeable between 929/954/f4i.

 

yes they have it. and yes, both the calipers and the pads are interchangeable(i'm finishing installing today), but still someone that doesn't like the sense of buying aftermarket pads could benefit from buying the 954 pads.. but the compound could be more agressive and hard on the brake rotors, which cool more slowly than those big ones from 954, so in some cases it could do only worse...
