Blue Dot Identification

[Shaun]

I have searched and found one post that identifies years and type of blue dot calipers, cross over lines to the other caliper and the like including a name, Sumitomo? However where I come to a problem, I need to rebuild a caliper as it is leaking by the seal and soaking the pad and coating the rotor. When I phoned the parts guy at the Yama stealer he says he needs to know what bike the caliper is off of so he can look up the part number. I've bought these blue dots third hand and do not know what bike they came from, yet. Apparently there is another possible name apart from sumitomo, possibly nissan? he wasn't very clear in his description. Is there any clear way to identify what blue dot caliper I have?

 A photo will be a big help. If that's not possable, could you measure the OD of the pistons? Does the caliper have a steel external fluid line? Sumitomo's are the only monoblock calipers that will mount to the FJ forks.

Hey there, no sorry I don't have a picture at the moment, I'm actually at work. No there is no external steel line between the calipers, and I've been looking around the net and it looks like my calipers will range in years from 98-01 R1, I think in 02 they changed to "gold dot" for a couple of years and then moved on to non radial mount calipers, so I think. Bike is a 90 and the calipers bolt up fine, so if the only ones that bolt up to the standard FJ forks is the Sumitomo's then through the process of elimination it should be them. I was trying to get a rebuild kit ordered so I can get them rebuilt for this weekend, but never expected that it would take this much effort for what may turn out to be some O-Rings.

Thanks for the input.

Shaun.........'03 was the last year R1s used the non radial calipers.........it was also the only year that the 'dots' were gold.....all previous years the dots were blue. some time during late '03, I believe for the '04 season, the new R1 changed to radial gold dots.
I have a set of '03 gold dots on my FJ.........is the only reason I know this.

And I think the first generation FJRs used siver dots.

Try checking the yamaha online parts fiche and you can confirm the part numbers.

If they bolt on they will work as far as I know all the monoblock calpers  (non radial) have the same bolt spacing and take the same pads. The only differance is some had the bango bolt on the back and others on the side no big deal the lines have enough flex to cover eather one.

If you don't all ready have one I have a master off a 06 or later FZ1

Thank you for all the input folks, the problem shall be resolved today and parts will be ordered. It was confirmed to my by the fellow I bought the calipers from that they are from an 01 R1. tqmx1 thank you for the offer but I do have a FZ1 master as well, I actually have just mounted the calipers and master just last week and I am looking forward to feeling the improvement.

Thanks Folks.

is the R1 and R6 the same, is it just 03 and up that fit the FJ stock fork? 
or 03 and earlier? is there something visual i can see to know it bolts right on,
or do i have to just know the measurements of the bolt pattern?
do we have a cross reference chart somewhere?

Travis,

The gold/blue dot NON radial calipers used on the R1, the R6, the FJR will all fit and work on the FJ.
The R1 changed to a radial mount caliper after '03 (according to Harvy).  I'm not sure when or if the others also changed.

BTW  I'm using '03 R6 blue dot calipers and they are great on my '91.

Cheers,
Arnie

Please excuse my ignorance, but i assume the radial calipers are the more square shaped ones that bolt on
the inverted fork set up?

all other ones fit? that would make it easy

Those are radial brakes.  Notice that the mounting bolts point nearly at the axle.  A conventionally mounted brake has mounting bolts that are parallel to the axle.

Just to clarify, the R1/R6 monoblocks only bolt up to FJ forks from '88 or newer models.
