Nissin 6 pot Vs. Dual brembo 4 pots.

[Nibor]

Hey guys,
Looking at a brake upgrade soon. I'm on a 98 m750, with the old 40mm mounts on some 900 forks. Currently 2pot brembo on the LHS.

Have been trying to hunt down sone 40mm 4pot , but can't find anything for a reasonable price, as I'd need new lines and a new disc or probably set. $$ is my main restriction in regards to mods.

Recently started reconsidering the nissin 6 pot. It was a possibility a while back until i saw the price of a set of calipers. But now I'm thinking why not just 1 side only?

How different would performance/characteristics be between these 2 setups? I have a larger coffin master already, was sourced for the dual 4pot setup. Would this suffice for the master if I got the nissin?

Cheers,
Nibor

I would look at getting a single 4pot brembo and an upgraded master cyclinder.  if thats not enough then look for the stuff to run a second caliper.

if it is sufficent braking, you will have saved a nice chunk of unsprung weight.

BOOM. good idea.

I'm incredibly confused:   The original equipment on the M900 was dual goldlines - each being 2-pad, 1-pin, 4-piston (30/34) calipers.   Not sure how you have fitted 2-piston calipers to them, or why. 


For a brake upgrade, the goldlines are "good" - but look at better pads.  Every OEM Brembo pad has been pretty crap from my experience.  Next step (co-equal step): check your brake lines - if you have rubber brake lines, its time to spend a few bucks to get some braided stainless lines - removing all flex from this part of the system.

Upgrade your master cylinder to a radial-action master cylinder - I suggest one from a new-fangled superbike (749-999, 848-1098-1198) or Monster (1100). The Brembo GP 19x18 is reasonably priced race piece - you'll need to run a pressure switch for brake light activation though.   Note, its a cast/forged master cylinder, and while its good - the billet ones are certainly superior (and reflect it in their 10x cost)

If you want to run a single caliper, I wouldn't hesitate to recommend the ISR 6-piston, 6-pad billet monoblocks (22-032-OA/OB).  I've got dual 22-032 calipers on my M900, and its awesome.

Here's a shot of the front end:

That is a family-size helping of brakes, right there.

Beat me to it, captain!

Money is the main factor here, so billet parts are out of the question unless you're shouting I like the idea of the single 4pot upgrade, but I don't want to want to change the setup again, hence leaning towards the dual 4s or the single 6.

not a bad price...

I've been tracking a single 4-pad set-up for a while now and have no complaints.  If you're going with this set up I would refrain from a large bore master unless necessary, as you'll have a rock hard wooden lever with no feel.  Bigger and more is not always better (but usually more expensive).  I've got a 999 radial but perfer the smaller bore coffin so that's what I run.   For you numbers types, heres a chart that might help.

Get out of here with that silly advice.  There's no feel whatsoever in a coffin master because its axial action - the lever and fluid don't act in the same direction.  The coffins were, originally, a downgrade from the original axial goldlines.   And its not all about bore - the pivot makes a big difference in how it feels.  That's why there's multiple 16mm, 18mm, and 19mm bore master cylinders by Brembo.     I love the 19x18, others like the 19x20.   I also have a 16x18, but thought the 16x16 was no good.

I thought the single caliper setups were just the 4-piston 2-pad goldlines (essentially "half" the two caliper system), and the only two piston calipers that jump to mind for OEM ducati equipment are either rear calipers or the 620/S2R800 black brembos which use an adapter plate to fit the forks properly

sounds like he's got a frankenstein system or something else.  all of the 40mm calipers have 4 pistons .  even going back to the mid 80s.. the F1 limited models (laguna, monti)  had the P432s on it with 40mm bolts.  (432 i.e. 4x32mm)

No 2xpiston calipers with 40mm mounts ever made by brembo.

The 1997 600SS was the first bike with a single front 40mm caliper (type 3034).  I don't remember what master is on that bike, I'll have to look when I get home, but I think its a PS13

I'm running a 4-pad caliper (has 4 pistons of 34mm diameter), CP211 pads, and a 16mm diameter goldline master on my M750 commuter.

It stops the bike just fine.

But, I'll be charitable and describe the lever feel as 'wooden'.

The Sport Classics had 2-pot calipers on the front, needed for clearance to the spoked wheels.
