Looking for a set of Sumitomo calipers MK63


Recommended Posts

Jerry inspired me , obtaining vented calipers.

Dimensions are almost same, only the width to the side is different.

Shims and springs are missing, I will collect them gradually.

Wires for the retaining pin caught my eyes, I think this is for quick replacing when at the track. Nismo features?

I like the wires for the retaining pins. I am going to make up a set for my upgrade. Thanks for the pictures Kats. I found that the DORMAN H36866 Brake hose is the replacement part for the original Nissan hose for use for the MK63 Caliper upgrade. They are less than $10.00 each. Let me know if I can help in any way.

Thank you Jerry, that is a very useful advice , when I need it, I will ask you to get them.

Your vented disc looks so cool, Jerry. That is why I could not stop myself hitting buy button!

Sorry if i dig out this very old thread, but i have some questions regarding this. I've been trying to figure it out for a few years now but i haven't found anything useful at all...
Maybe Alan @HS30-H has an Idea? Some of the comments quoted below came from you if i remember right...

1) On several places i've read that the Z-specific calipers are called "MK63-20S ", but i wasn't able to find it in any of my documents. It is never mentioned in any of the manuals which includes all the parts manuals, optional/racing/competition/Nismo manuals
nor the FIA Homologation sheets. Not even in the Japanese "Race and rally prep. manual". So i wonder where the "-20S" information bit can be found?

2) Is there at all any MK63 specific documentation? I have many special Service manuals for the transmission, diff, steering rack, Carbs, etc. but is there something similar for the MK63 (or brakes in general)?
Maybe by sumitomo or Nissan or NISMO? I've searched on my own and with the help of some people in japan. but nobody was even aware about such a document. However it seems like something must exist?
The only thing i was able to find is a drawing from the 2007 nismo competition parts catalogue:
nismo-drwaing-1.png

3) I've also read comments that there is an official instruction on how to modify the backing plates / Dust shields to fit the MK63 calipers. Where can i find this information?
The race and rallye preparation manual lists a set of (what i undestand) already modified backing plates to install, which is also described in the manual,
but nowhere i found any information on how to modify it by yourself to fit? Where does one find this information?

I have a guesstimate of what the 20S is, but I am know doubt wrong, so I will shut up....but on the cutting of the backing plates, I followed Jerry's pictures, then mocked up my backing plates and calipers to make a template (off the car). I haven't cut them yet, got side tracked.

I could be wrong here, but the MK63 was on quite a few models on Nissans (Prince's?) before the S30 came out, so could it be classed as a "generic" part, which just so happened bolted on, and/or Nissan made provision at design stage?

Interested what Alan has to say.

None of the MK63 calipers are "Z-specific". They were specified as Sports & Race Option many Nissan models of the late 60s through late 70s period, and in both vented and solid rotor variants.

The '20S' suffix corresponds with the width of the vented rotor used on the (wide) vented rotor type caliper.

From Nissan factory documentation:

@HS30-H, Alan - thanks a lot for sharing your excellent knowledge once again. This clarifies a lot.
WIth "Z-specific" i didn't mean a model made for the Z, but the ones (Straight nipple?) used for the Z (and most probably other models), since there were many slightly different versions around.
The race and rallye prep. Manual, for example, mentions that the ones used the C10 Skylines are slightly different, but would also fit, allthough no details about the differences.

Out of curiosity, may i ask what "nissan factory documentation" the one you posted pictures from in the post above exactly is?

Does that manual, by any chance, also have information regaring the backing plates?

Two different publications, both factory Competition Preparation manuals for models that are not S30-series Zs.

Do you mind letting us know what car(s) those "competition prepararation manuals" where made for? I'd really like to learn more about the topic and to find those manuals as it seems to have some interesting details, even if not z-specific...
Thanks again for your help.

@RIP260Z Thanks for the input. nice idea, but it's the same pad partnumber as used in the S30 Z's. I guess the pads are "genuine" items for the vented MK63-20S types used on various cars, same as the calipers.
See the different pads and parts listed here in the Nissan motorsports schematic catalogue picture below.
Note that the brake is only called "FIA" Brake caliper here in the title description, as it is mostly called in the US specific documentation. that's why im so curious about Alan's documents above since it's the documentation
with the most accurate description i've seen so far. and it's even english....

Hi Nils,

Yes, the part number is for the S30. All I am showing (on a different but related tangent) is the DS11 is clearly marked on the pads (and ties in with the DS11 on the paperwork). I am adding nothing regards any documentation regards MK63 manuals. That's why the post was "just for interest".

If anybody is wondering, i figured out that part of Alan's scans above are form the BS110 (RS240) FSM, Brake section.
Since most of that information is not z-related i won't put it online here, to avoid more confusement.
But if anybody is in search for said Information, you know where you can find it now.

No, in fact my scans are from two original sources: The 'Competition Tune-Up Manual' for the A10-series, and the 'Competition Tune-Up Manual' for the N10-series.

The Sumitomo MK63 type brake calipers were used as Sports/Race Option on many Nissan models, so the information is duplicated in many source documents including - as you pointed to - the BS110 '240RS'.

Ah thanks for the info. Funnily the information in the Nissan factory "BS110 (240RS) Competitoin tune-up Manual" (not FSM as i wrote above) looks exactly the same as in your scans (layout, drawings and text!).They must have simply copy & pasted the information from one to another manual.

No such thing as cut and paste back then. In the 1960’s Lyndon Johnson accidentally called the Blackbird aircraft the “SR71” its actual designation was RS71. A team of stenographers had to retype every document so as not to embarrass the friendliest President NASA ever had. To this day of course, the plane is still called the SR71 Blackbird and NASA still has one they use for test flights. 
For this reason, I doubt these documents were simple cut/paste.
