For those of you that have upgraded your brakes for the track, and put a Brembo MC on, did you notice much of a difference compared to the stock Nissin one? I've been thinking about maybe picking up an RCS 19x18, but don't want to spend that much money on something that won't make any noticeable difference. Thoughts?

I know that's why I started thinking about it. Just want to know if it actually makes a significant difference or not.

Makes a significant difference one of the best mods I've done.

I would suggest to save a few bucks, choose the ratio that works for you 19x18 or 19x20 and just buy that one, which is considerably cheaper than the RCS. It is very rare that people change the ratio, generally you find a setting that feels good and stick with it, so I find the variable system kind of useless.

I chose to stick with Brembo over Accosato, Braking or another brand as spare parts and rebuild kits are hard to find or don't exist for some brands, so if you have a problem or crash you are stuck buying a whole new mc as opposed to fixing, meanwhile they are readily available for Brembo.

Yes yes yes yes yes yes yes

Very first mod I did to my 636. Although the stock brakes on the 636 are pretty good compared to what I felt on other bikes, it still makes a very good difference especially if you plan on track riding. It is completely worth the money and a fairly easy mod to install yourself.

One of the best things I like about the MC is when I start experiencing brake fade at the track, I can turn the dial on the master cylinder as I'm riding and have better brake response.

It's worth it. Do it.

Well, I had to ask the previous owner who made the master cylinder since I need to get a more adjustable lever.

Last track day the exercise was gas or brake. Had a hard time with brake and down shifting, with one finger on the brake and blipping the throttle caused all sorts of front end dive.

The answer was brembo master cylinder.
I can get this thing to stand on it's nose with one finger. Also have Nissan calipers.

If you have money to burn.. sure.

If not... the proper fluid and bleed will perform just fine for the track.

As you know.... to race in the MotoAmerica SuperStock 600 series you have to run the stock master cylinder.

My set-up is as follows:

Braided lines.
Vesrah RJL XX Pads.
Castrol SRF Fluid.
Speed Bleeders.
Vortex Adjustable Lever.
Stock Master.
Stock Calipers.
Stock Rotors.

Take the time to bleed your brakes correctly.

I've had zero brake fade all year.

Can you elaborate on that? Isn't RCS just a model name? I was basically looking at the RCS either in 19x18 or 19x20. I believe the 19 is diameter of piston, and the 18-20 is the length of travel of it, right? I can't say that I know what works best for me unless I try them all. I don't even know what the ratio is for the stock Nissin MC.

I actually didn't know they don't allow MC change for that class. But that's good to know, because then clearly the bike is more than capable even with the stock hardware. I usually don't have problems with brake fade, as long as bleed it more than once a year lol...it's just that the brakes don't feel all that great to me on this bike. Maybe it's because I was so spoiled with the Ducati 1198 Brembo brakes over the last 4 years. At the same time, I have yet to run off track ever since I got the zx6r, because I've never had any issues with slowing down enough...I guess it's mostly the feel of the brakes that I don't really like. Just feels like they're not as sensitive to the lever pull, and there is too much lever travel for my liking.

Good Lines, Good fluid and Good Pads....

That's the answer...

And you don't even need the XX Pads.... The straight up RJL's are fine too.

Oh yea... I bleed mine (push new fluid in every race weekend).

Plus blow compressed air past the pads every wheel change....

And then soap and water with a tooth brush once a weekend.

Damn! That's dedication! In a regular season, where nothing unexpected happens, I probably only flush the fluid twice, and I clean the calipers whenever I change pads...which is like once a year or 1.5 years depending on how much I ride and how long the pads last. I'm using SBS dual-carbon pads now and I really like them. They seem to last long too.

Of course, I'm also not at your skill level, and that plays a factor too ;)

The RCS allows you to switch between 19x18 and 19x20 via a small screw in the lever. Basically the 20 is more progressive feel with less initial bite while the 18 is less progressive with more initial bite, (if I'm remembering correctly, I'd have to check the brembo site to confirm) But yes 19 refers to diameter while 18,20 refer to length. What works best for you would come down to your riding style and what you are looking to gain. My point is if you know what you are after there is no need to spend extra for the RCS.

Ah I see. Thanks for clarifying. Didn't realize the RCS is adjustable.

Any idea what the size of the stock Nissin one is then?

Overview of a Brembo Master Cylinders

The second number is the distance between the piston and lever pivot. A bigger number gives you more leverage, aka more braking force with the same force at the lever. That is all you are adjusting with the RCS, it doesn't have anything to do with progressiveness or anything like that. The RCS won't be legal for many club racing super stock classes because of the adjustability.

What brand of lines do you run? I personally like the Y lines, do you know who makes it for our bike? I got a 2014 ZX6R.

Thanks

I do the exact same. Plus put a few drops of brake fluid on the caliper piston and push it back in. This makes sure the piston pushes and pull back in nicely with no sticking.

I use brembo Z04 pads. They make a huge amt of brake dust but work amazing.

Oddly my lines are off my old 04ZX10. But I'd prefer the "Y" lines too. That way only one line and a shorter banjo bolt is used at the master.

Too many times I have crashed and dented the forks with the longer bolt.

I'll have to look around to see if anyone offers "Y" lines....:O

The first thing I did with my 6 was pull the RCS 19 I had on my 06 zx10, and the Spiegler SS lines. Swapped them over to my 6 and it was a night and day difference.

There is no doubt that the RCS 19 and Spiegler SS lines are the sh!t. :smile
Add good fluid and pads, and Bam... you've got the best brakes ever.....!!

However... You can make the stock master work... as it's a class requirement.
