Title: need help to ID MC
Post by: Paul.1478 on July 28, 2020, 05:42:11 AM
I got some new blue dot calipers and a MC. Problem is I do not know what the MC came from. I asked RPM and was told there are many MC that look the same but different inside.
does anyone have any ideas on how to ID this so I can get a rebuild kit???

thanks for looking..
Paul

I'm guessing FJR 1300. The masters have different bore sizes stamped on the body below the sight glass, bit hard to see but looks like 16mm on yours.

The lever looks identical to the one I have on my FJ - I'll have look at the master cylinder first thing in the morning and compare it - it could also be from either a FZ1, or a YZF 600R Thundercat.

thank you for all of the replies. It does look like a 16 I've taken a better photo I've also found some other numbers below the master cylinder maybe this can help.

I'm hopefully headed to the hangar soon, I'll see if I can read the numbers on my FZ1 master cylinder.

I can't get to read/photograph the numbers on the bottom of the master cylinder on our FZ1, but it looks identical to Bryan's. The one on my FJ also looks identical.

Strangely, my FJ's master cylinder, which was supposed to be from a Fazer 1000/FZ1, does look externally identical, in every way, except that it has a 16 marked on it where the 14 is on the one on the actual FZ1 bike, sat next to it in the garage  :Facepalm:

Our FZS 600 has the same 14 cast mark on it and also looks externally identical to both of the others (the 600 came standard with blue dots too).

Thanks for checking. I also posted on the FJR form. Maybe it is from an FJR.

I may have to just use it and hope it does not leak and look for one that has been IDed and replace it at some point.

Early model FJR's had a 14mm master and came with blue spots, as the model progressed the bore size went up to 15mm then 16mm. No idea what the latest model has master or caliper wise, but I'm guessing their totally different.. My master came off a 2008 FJR 1300 abs and has a bore size of 16mm and came complete with silver spot calipers. I sold the silver spots as I already had blue spots fitted and with the new master fitted the feel of the brakes was way better, even though the bore size is about the same as the standard 5/8 inch.

A lot of Yamahas probably used that same master just with different size bores, even if not sure what model it came from maybe specifying the bore size might help in getting the right rebuild kit.

Good information. I will try and look up the parts breakdown on the different years FJR and see what one (s) are  16 mm.
Thanks.

I have looked through the services manuals for FJR and they do not have a 16mm MC. only 15. I have to assume that 16 on the one I have is 16mm but must not be FJR, I looked at a few years of R1 they also are not 16mm.
Strange.

so this must be an ABS one, but I do not find any specification on ABS.
Thanks for all the info guys.

This link suggests the 16mm nissin MC is common on Suzukis:

Peculiar that the lid doesn't have "YAMAHA" on it...Most of my Yamahas do.

very interesting. I think i am going to give up on it and find a FJR one with a correct year. Very strange. At least i have 2 blue spot calipers that look to be in great shape. so no complaints

Of the 3 I have (one on the Fazer 600, one on the Fazer 1000/FZ1 and the 16mm one supposedly from a Fazer 1000/FZ1 on my FJ 1200), none have YAMAHA on them, but all 3 have NISSIN on them !

My FZ1 MC does not say Yamaha on it. I just took it for a ride.  Forgot to take a picture.

Sell the 16mm m/c
Get the 14mm m/c

I found an FJR one from a 2006. It should arrive this weekend.

I don't see how I can sell the 16mm one when I have no idea what it came from.

I agree with pat it needs to be the 14mm nissin the 16mm brembo gives a firm lever pull that lacks feel the 14mm will provide better feel with a 2 finger pull and better feedback

I disagree about the lack of feel, yes the standard FJ 5/8 inch feels wooden and needs a firm four finger pull but the FJR 16mm I have fitted has a soft easy two finger pull to it. I look at it this way, if it was deemed good enough for the heavier FJR then it's good enough for the FJ, FJR's were never known for having weak brakes.

Other than the adjustable lever and the three terminal stop switch on the FJR, the FJ and FJR axial m/c's are both essentially the same and share the same bore diameter.  5/8" = 16mm
Although, certain year FJR's used a 15mm m/c

Bonesy you're in for a treat if you try a smaller 14mm m/c

With the adjustable lever set to suit me, I've gotten quite used to just using one (index) finger braking on the road. Plenty of feel, control and power.

On track I always used 2 finger front braking on my RSV with its Brembo's and haven't had my FJ on the track since it's new brakes, but would still go with 2 finger braking because the heavier braking necessary.

Only two terminals for the brake light switch on my master Pat. I am aware the bore size between standard and my FJR 16mm are the same, but for whatever reason the FJR master has a much better feel to it. Pull the lever on the standard one and it goes so far then feels rock hard, the FJR has a soft feel to the lever and has better modulation. Early models started with 14mm masters but then got bigger. Mine is off an ABS model but can't see why that would make any difference, either way I'm happy with its performance and will stick with it.
