FZR400 Caliper Generation?

#1 Post by Hellgate » Sun Jul 14, 2013 7:23 pm

Okay forum I think I messed up. I ordered '90 FZR400 front calipers. The spacing is fine for the fork leg (F2), but the offset appears to place the caliper too far inboard. Did I buy the wrong ones? Looks like a quick pass on a mill can square it away pretty easily.

Thanks! :smt023
Cheers!

I believe the 3TJ calipers are the ones you need.

Are the ones you have branded with the name "SUMITOMO" ?

I bought a FZR400 A from 1989 and they are the sumitomo affair and I have a 1986 F2 RD and I remember they didn't fit the F2 leg; I didn't bother because I was swapping the whole suspension.

So looking at the Japanese site from the previous posted link which are the ones u got?

Careful with the disc diameter because a very big difference between the 2 bikes (FZR & RD) may cause the edges of the FZR pads miss the contour of a very smaller RD disc

Thumbs up for the Japan sites with info/pics.They are GREAT :smt023 :smt023 :smt023

The 400 calipers you want are from the rare RR model. Not the normal bike.

I am running TZR 3MA calipers. They were a bastard to bleed, and are supposedly known for drag... Oh well.

Did it work ?

I´m trying to swap mine for a better option.
I bought 87' FZ600 Front Calipers...but it didn´t work very well...it´ll need some great mods to make it work.

Are those FZR400 (3TJ) Plug n' play ?

Cheers!

I understand if you want to keep it original looking, but instead of chasing down rare 30 year old calipers you can get a pair of 4 piston Triumphs or some adapters for R1 blue spots and have much newer hardware that you won't have to rebuild to use.
I rode a friends VFR years ago and thought 'wow, I wish I had brakes like that'. The 955 Daytona calipers and an R1 radial master got me there for about $100. Unfortunately I'd already spent that much rebuilding the RZ brakes and buying new pads and braided lines for just a small improvement.

Actually, I still have a question.
Which Fork will work for the FZR400 calipers ?
Because I was wondering, if the American RZ´s forks, European RD´s LC2/F1/F2 forks and Brazilian (1YH) RD´s forks has the same bolt caliper measurements...aparently not, right ?

I´m trying to do the swap on a 90' Brazilian RD350...
It just look like the European´s F2, but I´m not sure. How can I check it ?

Nzminis,

So...I´ll look for those!

RuZty,

I bought a pair of R1 blue spot...including the master cylinder...those were my first plan...but as you thought, I really would like to keep the original looking, thats why I ´ve changed my mind about using it...

So my new plan is to keep the R1 master cylinder and buy a pair of FZR400...
I already did the full FZ600 rear set...and it was easy.

Anyway, thanks for the advice! =)
