Large or small diameter master cylinder for a single rotor brake setup?

[koko64]

Should brake pretty hard even with one disc, since the Brembo 4 pad caliper reputedly has the most bite of axial calipers. That extra bite would be useful with a single disc application. A fully floating Brembo stainless race style disc could work. That deals with the pad issues. Then just swap the M/C and you're in business. You're then dealing with well known and understood parts with plenty of advice available.

Pity about the ISR parts. They had a certain look.

Can't argue with saving money for other mods.

That's why I  so pumped about the isr stuff also. Crazy big calipers, smart design with the integrated masters.  But some of the prices were not that far off than all brembo stuff with the direction I'm going.

I still may go for it. That's a bad ass caliper man. I wish the integrated masters were radial though...it appears those are only axial.

I sacrificed some precious time out of my hectic schedule checking out Brembo HP 320mm/5.5mm fully floating discs. According to the Yoyodyne site, they work very well with with 4 pad calipers for which they were made.

I just missed out on a pair of 3500 mile 749 calipers for $290 because of my damn waffling on this issue. Now I feel obligated to buy the ISR.

Power Barn seems to have everything ISR related in stock.

A comment Chris Kelley once made has always stuck with me, it was something along the lines of; "it would be a crime to buy any other rotor than Braketech". Not that his word is necessarily gospel but aside from this forum he's pretty much always been my "Ducati Totum" since I got into Ducs 6 years ago, lol.

What about using a 6 piston radial caliper off of a japanese bike?  You would have to swap out fork lowers but it would open up your options.  All of the showa 43mm forks I have compaired have all had the same threads on the fork slider.  A bit of heat from a map gas torch & a band clamp & they will seperate and swap over.

Kinda opens up an already festering wound there, which is my regret for not doing a GSXR fork swap to begin with as opposed to the Matris carts.  Swapping bottoms is still a good idea, but I'm not sure that makes things any easier/more economical in the end, especially after figuring out a new front fender.

This is before I noticed the rear master cylinder... I'm going to call and maybe see if they're willing to deal a little bit. Something else that may or may mean anything to some people is the serious upgrade of the rear brake performance. I don't know if I can get used to having a serious rear brake though after 20 years of never having one.

 I don't know if this will be of any use to you, butt I thought of you when I was reading this:

Yeah I've read that numerous times on .ms and the other Monster forum. I specifically recall Chris Kelley kind of "going at it" with Shazzam, something along the lines of regardless of how technical this info is, switching to a radial GP pump from the OE axial was one of the best braking upgrades ever in terms of both feel and power.

That seems to be a common consensus among people who track their bikes regularly. It's why I'm still hesitant to return this RCS set for the ISR, given how much  the RCS masters get.

But honestly, all of us with the exception of the SC, 620 and some of the 90's baby Monsters get awesome brakes as standard equipment. I don't think many of us really *need* to upgrade.

FWIW... much to my surprise, the least WOW factor upgrade I've done was the switch from 16mm coffin master to a StreetFighter radial master. Noticeable, but not WOW.

Much more important for me was:

1. going from modest stock S2R800 discs & calipers to 320 semifloating, 4 piston '996' calipers and 16mm coffin master.

2. going from stock'ish pads to Brembo sintered HH

3. going from semifloating 320 discs to 320 fullfloating

4. the above mentioned master upgrade

YMMV

On a former build I put Brembo radial masters on and the bike had a simple 4 pot Nissin caliper. The Brembo unit was rated higher and suggested a dual caliper. What I had in return was more "leverage" so to speak in that it look less force to perform a stop. It took a minute to get used to but in nyc stop and go traffic it was quite comfortable.
The 19 with a single caliper *might be just fine. YMMV

Noticed that twin 4 pads calipers, custom braided lines, etc came up in the parts section. Looks a good deal.

Thanks for the heads up! I've sent him an email.

What I may just do is go with Brembo OE components and possibly upgrade next year.

My pleasure.
