4 piston brake upgrade for '94+ using Nissin calipers
« on: July 05, 2018, 08:28:28 pm »
There are a few threads on this upgrade already but had to dig to get all the necessary info. For the sake of others who still might want to do this I thought I'd publish my own experience.

My major reasons for upgrading were:
  • Better brake lever feel
  • Easier pad change
  • Mechanically more efficient (pistons are the only things that move and that work load is shared over 4 vs. 2 of oem)
  • Better looking

Choice of Nissin over Tokcio Caliper
  • Cleaner look (totally subjective)
  • Maybe slight price advantage to Nissin

What you need to do this mod:
  • Calipers from a Honda CBR 600 F4 - F4i All Model Years, 2000 - 2001 CBR 929, 2002 - 2003 CBR 954, 2003 - 2004 CBR 600RR or Honda RC-52 2001 SP2 and up.
  • SV650 Adapter Bracket (SV/DL brackets are exactly the same)
  • (4) M10x1.5mm x 40mm Stainless Steel Button Head (24ft/lbs)
  • (4) M8x1.25mm x 35mm Stainless Steel Socket Head (22ft/lbs)
  • (4) M8 Stainless washers
  • (4) 5/16" ID x 7/16" OD x 3/8" spacers

Everything bolts up pretty easily and there are no clearance issues. For ease, I would work one side at a time. Start by unbolting the current caliper and support it with a wire until you have the new caliper mounted then switch over the brake line working quickly enough to avoid brake fluid spillage. For the adapter to fork bolts I would locktite them for peace of mind. You could also safety wire them if that's your thing. After both are completed, bleed brakes per usual.

Beyond that I suggest rebuilding both donor calipers and inserting new pads before installing.
It is also worth noting that the FA296 pads used in the Nissin calipers are a tad large for the braking surface. I used a grinding wheel to remove about 1mm of material from the lower edge.

Here's the finished product.

Great job. I did this 2 years ago.  Maybe this can be moved to the tech page.

I "upgraded" to four pot Nissin calipers a couple years ago. They came with the ST1300. ;D

Edit: I was wrong. My Nissin calipers are three piston units.

this applies to the 93+ models only I expect?  or will it work back to the 86 version?

thanks

Correct. Earlier versions need a different adapter bracket which I think needs to be fabricated independently.

Somebody correct me if I'm wrong, but 86-93 should be the single piston calipers and 94-06 would be two piston calipers.

YOU are correct, and it seams the O/P erred in his choice of saying "93+" models..

to clarify, it should be read as "94 and UP"..

the '86 thru '93 models A1 thru A8 were single pot, the wheels noted are a 6 spoke (3 pairs of 2, straight spokes)
 the '94 and up (A9 model, up) used douple piston fronts, the wheels are seen as having 5 spokes, that are curved.

hope that clarifies it better, and I hope the O/P "modifies" his post title to say "94 and up models"

ride safe,

Thanks for the correction. I had just updated based upon what Cal asked but didn't even think to question accuracy. Post updated to reflect correct info.

Thanks for this info, mnbikeguy.  I'm working on a very similar upgrade to my '01 and appreciate the measurements.

I'm installing:
- Nissin 4-piston calipers (gold) from an 00 CBR 929RR, axial (not radial) mounting
- SV Racing Parts brackets (DL650 model.  Sounds like DL1000, DL650, and SV650 brackets are the same)
- New EBC Pro-Lite rotors (stock size, so the brackets fit)
- New EBC HH sintered pads

Just finished rebuilding the calipers and installing the rotors and now I'm hunting down the hardware.  I bought cheap hardware of the right sizes just to check the fit of things, but I'm going with black button head bolts if I can find them.  The pads are arriving tomorrow.

Obviously I haven't assembled it enough to test ride, but your measurements appear to be spot on.  I'll post pics in a separate thread when it's done.
"You put antiseize on those, right?"

01 C-10, Progressive 465 rear shock, Race Tech emulators and 1.0 springs, Russell Day-Long saddle, Spiegler hydraulic lines, Cee Bailey windshield.
In process:  EBC rotors, Nissin 4-piston calipers

Did the Nissin calipers a few years ago, and I'd say it was the best mod I could have done for me C10.  I'm hard on the front brakes, and the difference in stopping power was very noticeable.
