Brembo 19mm RCS Corsa Corta Radial Brake Master Cylinder Install Review | Sportbike Track Gear

www.sportbiketrackgear.com/br...
The Brembo 19RCS Corsa Corta Forged Master Cylinder is Brembo's new addition to the RCS line - our most popular selling aftermarket brake master. The variable lever ratio makes this the perfect option as it allows the rider to tune the feel in a way that best suits their individual riding style.
ONE MASTER CYLINDER, THREE RIDE MODES
The selector operates a cam mechanism to let the user choose between three different responsiveness settings.
In the Normal setting, indicated on the master cylinder with the letter N, the bite point starts more gradually, making it suitable for city riding or braking in poor grip conditions.
In the Sport setting, indicated on the master cylinder with the letter S, the beginning of the bite point is shorter than in the N setting. This setting produces a more dynamic response suitable for sportier riding.
Lastly, in the Race setting, indicated on the master cylinder with the letter R, the position of the cam mechanism shortens the initial stage of the bite point even further to produce the same immediate response of the master cylinders used in MotoGP, letting the rider reach the bite point of the brakes instantaneously. This setting is ideal for use on the race track, where every hundredth of a second shaved off a lap time counts.
By simply changing from one setting to another, the rider can configure the braking response and feel of the bike immediately and predictably.
TECHNICAL FEATURES
Material: Forged aluminium
Piston mm: 19
Lever ratio: 18-20
Lever type: Folding, standard length
Single/double disc: DOUBLE
Surface protection: Hard anodized
Weight (gr): 350
Brake light micro-switch: Yes, switch is included
Banjo Bolt: Double banjo bolt with copper washers included
Items required to complete installation:
We suggest using the Brembo Brake Reservoir Mounting Kit (Brembo Part# 110.A263.85) as it includes a reservoir, bracket, hardware and tubing.
The 19RCS includes a double banjo bolt with 4 copper washers. This will work if you have a 2 brake lines coming off the master cylinder. If you only have 1 line off the master you will need a M10x1.0 Single Banjo Bolt Brembo Part# 06.2228.76 or equivelant.
If you intend to use your stock reservoir you will require a length of 6mm Tygon 2375 Tubing and 2 3/8" Spring Clamps.
Brake fluid will be needed. We suggest replacing all of the fluid in the system when you install the master.
The Speed Bleeder Bag and Hose Kit is a real asset when bleeding the brakes. It can keeps the job clean and can be reused.

Hey Brian, I damaged the original master cylinder on my 2020 street triple R, I believe it uses brembo m4s. If I wanted to replace it with one of brembos RCS models would the rcs19 be the one I go with? I've seen some conflicting information on which lever is for what kind of brake online.

[@tedbruntzel7315]

I've got a 2017 car 1000SP // I desperately need steel brake lines. It's currently a single banjo at the brembo. Purchase from your site 2 years ago, still need to install

This is an excellent upgrade. - Van

[@djwordnyc]

Hey Van, another great vid. Does the brake pressure switch just pop-off the master cylinder? I don't see a mounting screw head on it. Thank you!

[@sportbiketrackgear]

It is a brake light switch, not a pressure switch. It has been a minute but I think there is a small screw that holds the switch on like you see with the OEM masters. - Van

[@djwordnyc]

@@sportbiketrackgear Hey Van, thanks for the response! I figured it out, it's not a screw, it is just plastic pins that push into the master. The pins protrude from the brake light switch. I just put a small flat blade between the switch and the master and it popped right out.

[@mushrume]

i ordered the brembo mounting kit and i found that i cant get the black clips all the way on the tube connecting the res to the mc . they dont open enough . was wondering if that was a one off or just how they come . did yours go all the way on the res side ? many thanks .

[@sportbiketrackgear]

The clamps are for sure a pain in the ass to get over the hose. If you can not get them to go over I would use safety wire instead or hit the hardware store for a little larger clamp. - Van

[@jsalemi9711]

Ian, I have a question on a 2020GSX-R1000R master cylinder. The bike comes with SS lines and I installed Vesrah pads. Canyon ride and upper intermediate tracker. My question to you is that being at my level I don't trail brake and will probably have to since riding a liter bike compared to a Triumph ST. Does this new Brembo model master Cylinder work well with trail braking and hope you know what I'm referring to. I have a friend that has a new R1 and he has changed master cylinder as well as pads, has a very short through and for the canyons works good but for tracking I would think that it is way to touchy. Maybe that would work for someone with a lot more experience and faster rider at a much higher level of skill! Please let me know what your opinions on my thoughts.

[@sportbiketrackgear]

I ride pretty well and use this at the track. IMO this provides more feel than the OEM master ever could. Much easier to use and it allows for adjusting just how the lever feels and power is applied. This is an excellent mod for track riding. - Van

[@mart_x_inez4996]

Sorry for commenting on a video that’s a year old but did you end up changing calipers too? Is this master cylinder only compatible with a certain caliper or does it not matter?

[@sportbiketrackgear]

No need to change the calipers. This master is an excellent upgrade while using the OEM calipers. - Van

[@biboguy1]

Hello, I have a GSX-R 750 and I ordered the Corsa Corta master cylinder, but I did not order the brake fluid reservoir kit; I am wondering if I can re-use my OEM reservoir ? and if it is possible what do I need to modify? I found some reservoir mount brackets online but I could not find a 6mm hose anywhere. Please advise. Thanks.

[@sportbiketrackgear]

It works best with the Brembo reservoir kit which is why we try to keep them in stock. That said you can use the OEM with a new mount and some Tygon tubing. We typically have all of that here as well. Shoot the team an email on [e-mail] and they will help get you sorted out. - Van

Need an aftermarket master cylinder cause my stock ones on the track bike kinda went pffft. I have a 2020 zx6r B-/C+ trackday pace. Which one exactly should i get? Im kind of confused as to which one will suit my needs/bike

[@cal525]

4:23 I checked the user manual, it said as below, so I am confused now. the lever ratio adjustment (Ratio Click System) that permits to fix the lever ratio on two possible settings: 18mm for the maximum brake power control, 20mm for maximum readiness of the brake system.

[@sportbiketrackgear]

I mixed them up in this video, all apologies. That said I have done a ton of laps with this master and love it. Makes it much easier to go in deep on the brakes under control. - Van

[@cal525]

@@sportbiketrackgear Greetings from Hong Kong. I think the thing you said in the video is correct, I did some search online and it said 18mm has more tolerance and 20mm is more like for racing. I also tried it on my own bike, the red pivot on top (18mm), the braking power is more gentle and precise. I totally forgot that I can change the lever ratio adjustment before watching your video, since the corsa corta was installed for quite a bit of time. And my bike was set to 20mm all the time and I think it was too powerful. Thanks for the great videos and keep it up man.

[@cal525]

The user manual is just confusing, not your fault though. Maybe because of the poor translation.

[@maarrsseelli]

So for 1 finger brake, i want max brake power when the finger gets tired. Should I leave it on 18 or 20 ?

[@sportbiketrackgear]

20 - Van

[@HighGrade_FireBlade]

Hey van. I ride a CBR1000RR. The nissin master cylinders on these bikes notoriously have a lot of travel. I think Honda does that to make their bikes more user friendly if that makes sense. It’s not like my brakes are weak, the lever just moves too far before the brakes kick in. Is this product something that will help with that?

[@sportbiketrackgear]

Yes a Brembo Master Cylinder will be a massive improvement over the OEM unit. More power, more feel and all that travel will be gone. - Van

[@HighGrade_FireBlade]

@@sportbiketrackgear I also notice that no matter what kind of fluid I use (RBF600 changed every other oil change), I still get about 1-2mm of fade if measured at the end of the lever. Street riding, track riding, whatever; as soon as the front master starts to see action it fades a little. Master and calipers were just rebuilt and I can leave a zip tie on the lever for days without leaking anything. I’m just astonished at how poorly this Nissin MC performs

[@begood9531]

I ordered a this master from you guys and it didn’t come with a registration card a screwdriver really nothing. Not that normal pack of stuff you get. Why is that?

[@sportbiketrackgear]

I have been told Brembo has discontinued the warranty card and now it sounds like the screwdriver may have went away as well. Please reach out to the team on [e-mail] and have them investigate. KZbin comments are not the best way to do this. - Van

[@Street765R]

How about buying right RCS for exact calipers? 17 or 19 for M4.32? Can I just slice brake light switch and connect it to factory cables if it won't be p&p?

[@sportbiketrackgear]

If you want to go that route Brembo offers a fitment chart on their site that will display the size they recommend. Most often times this recommendation will keep the braking performance more in line with the OEM. For most modern bikes 600cc and up riders are choosing the 19mm piston for track riding. This is what we have used on our bike and prefer it. - Van

[@northrider8453]

Does it hit the panel gauge or some fairings during turning left?????

[@sportbiketrackgear]

We do not have any interference issues with this master cylinder on our bike. The setup of the controls you have on your bike may be different than ours so the outcome could be different. Most will not have any issue. - Van

[@kamikazekhan]

Should I go with RCS 19 Corsa Corta for my Panigale V2 with Brembo M50 Brake calipers or RCS 17? I hear mixed reviews with most people saying that M50 Brake Calipers have 30 mm pistons and RCS 17 is the right master cylinder. Any suggestions?

[@jsalemi9711]

Ian, short throw on the lever and bites very fast. He has adjusted this and it's the best he can get it. For me it wouldn't work at my level of tracking, way to twitchy.

[@sportbiketrackgear]

This master is for sure more sensitive than the OEM. - Van

[@Uninfluenceable]

I think there's some confusion in terminology used in the video. At the 18 setting it takes LESS effort to pull the lever, but with more lever travel for a given braking force, while at the 20 setting it take MORE effort to pull the lever but with less lever movement for that same amount of braking force. Its basically trying to mimic both an 18mm and a 20mm diameter master cylinder piston through the use of fulcrum/leverage. A smaller than stock dia. master gives you a soft but mushy feel that is easier to modulate, while a larger than stock master give immediate bite but at the expense of being wooden feeling. Most modern sport bikes come with 19mm masters, hence why Brembo gave you the 18 and 20 (equal to millimeter) settings.

[@jsalemi9711]

Ian, I would think the best of both worlds? Please educate me if i'm wrong!!!

[@pravesh736]

The confusion here is u. The 18 and 20 is not diameter of the cylinder but the fulcrum to load gap on lever. Diameter is constant at 19 for this.

[@plintus9892]

[@mr_sowong9464]

@@munkeemunks look at it this way, hydraulic master and slave cylinder is just like front sprocket and rear sprocket. The smaller the master cylinder (assuming same slave cylinder size) makes a lighter pull and more precission. If you get a bigger caliper and use the stock master, you will pull so deep its not even practical (the lever could probably touch the handlebar). On the other hand if you get a bigger master cylinder and stock caliper, it will be heavy, and you can't brake precisely because you touch that lever with a little bit of power and suddenly you go into full brake mode. So just like front and rear sprocket, smaller front and/or bigger rear, less work more torque, bigger front and or smaller rear, more work less torque. Hope that helps

So how do you decide which model you want? I've heard so much conflicting stuff; folks are saying 17mm for me, which sounds right, but all from people who've never raced, never installed a master. And no one has an exact answer because 1: the bike is so new and 2: no one should technically bother with this.

The regular 400, they say, takes a 15. With one disc and some dogshit pots, sure. And the zx6r in most places I looked, says 19, most of the time. So makes sense to me, 10mm larger disc, but only one of them: 15mm. And 20mm larger dual disc with 32/32 pots: 19mm. That leaves me at 17, right? Did I talk myself through this one?
