nissin master cylinder?

Hey it's me again. First off, I did a quick search and couldn't find the answer I wanted lol. So coming off my old bike (zx6r with a nissin 19mm radial master cylinder) the brakes on the SD feel... Good but they don't have the same bite. Has anyone tried to put on a nissin 19mm? I really loved the way that nissin grabbed. I know that the brembo rcs something or other is another option but I did love that nissin and it's way cheaper.

While adjustable, an RCS MC won't bring much to the party on an SD. There are some here that run them (I use one on a bike that used to have a NIssin - LOL).

My experience with Nissin MCs, is that they seem to be really susceptible to fade ... Then again, my applications of them where I experienced this poor performance, have been somewhat extreme. Not atypical for most OE MCs.

As for the initial bite ("grabbiness" - ?), this - for the most part - has more to do with the friction components (pads and rotors). Yes, you can get more braking force from less lever travel with a different MC, which of course reduces control for a given lever distance displaced. The friction aspect, will remain the same. If you're using a pad compound with less initial bite, that won't change.

I'm assuming in all this, that your fluid is fresh, and properly bled - which if not done in the last year, is a first step toward improved performance. Thorough cleaning of pads, rotors, and calipers never hurt either.

YEah I just bled the lines a day ago. I'm wondering if the pads on it (Used bike) are not as good as they could be. Maybe they are glazed even. The brakes as of now are decent but slightly underwhelming in their stopping power. I'll give brake pads a shot first.

I'm also toying with the idea of getting new rotors. These ones are very slightly warped. Just a very tiny bit but I can feel it at very low speeds when braking.

They may not need to be replaced, if it's slight ... They can often be straightened.

I know what you mean.

Working in a bike shop and being around a lot of bikes is good for things like this. NIssin or at least the bikes I have in the dealership with Nissin MCs (mostly the MV AGUSTAs) have a soft initial pull and then a very sudden and distinct bite. Which results in great lever feel and feedback, or at least they do if you ask me.

Every OEM setup with the Brembo Radial or RCS MC on any bike I've ever ridden does not and has never had this feedback. From the 1199 Panigale S Tri-Colour (RCS MC), to the MV AGUSTA F4RR (RCS MC), to the 690 DUKE R (Radial MC) or the 1290 SUPER DUKE R (Radial MC), they all feel the same. As you pull the lever it progressively gets harder to squeeze but at no point while riding are you able to really gauge the exact initial contact and bite of the pads. This is why I've always considered Brembo MCs not as good as the hype and Beringer always a superior product in terms of feel. The reliability and stopping power of the Brembos is bloody excellent, I've just never liked the lever feel. What I do about this with my new 1290 SUPER DUKE R whilst trying to not spend too much money on the brakes, who knows because I ain't spending money on Beringer MCs after all the other more necessary mods I have planned.
