Brembo RCS 19 and Fren Tubo Brake Line Upgrades

you think?

I wouldn’t think the GP4-MS would be THAT big of a difference to the ABS

Lots of guys running them
Why would it? It’s the exact same size caliper as the OEM. And the ABS makes corrections based on wheel speed, can’t see how calipers would make any difference. I have different sizes calipers and masters on my bike and the ABS works fine
 
You missed the point, they were trying to sell me the 19 to alleviate brake fade which is completely bonkers. One has nothing to do with the other

exactly, I would even go further abs say that they weren’t trying to sell you them to prevent Brahe fade, they thought they were dealing with somebody so novice that they were trying to sell you them based on an imagined fear of brake fade that you had never pushed the bike enough to experience lol

I meanI can kinda see where it could affect them in that the ABS uses a kind of pulsing mechanism, so if you change some valve or tube size, it could potentially mess with it….but I hope/think that the GP4-MS are close enough to the Stylemas that it won’t affect the ABS much.

maybe someone like Mick or Endo can weigh in.

The brake lines are constantly full of fluid so, the actions the ABS pump takes aren’t going to change no matter what the caliper is. The only big difference between the stylema and the GP4-MS is the stylema is cast and the GP is billet. It has a slightly better build quality and materials which will result is better cooling, thus better performance, but other than that they aren’t much different. Kind of a waste of money tbh.

I have full confidence the RCS 19 with EBC HH Brake Pads and the ability to switch between 18-19 will be fine for me and the couple of track days I hope to get in this year.

Be interesting how you find the feel. The adjustable element, 18 to 19, is a change in leverage by the lever, it doesn't change piston size. But, if you have more leverage, presumably you'll need less force on the lever, and perhaps get more feel?
And, as mentioned, depends what 'feel' you prefer.
I did try both, and found the 17 gives easier moderation whilst trail braking, and less effort required at the lever.
And, I didn't find the RCS gave me any advantage over stock, but they look a bit nicer :)
 
^ I concur. The OEM Brakes are fine for everything the street can throw at you. I wanted the upgrade brake MC's after many years of looking to swap out aftermarket clip-ons to my 848, 1199S etc. The CNC racing on/off/ launch switch will add a little touch to the bar area.

I think having the 18-19 Lever Ratio adjust-ability might work well and since I am not a ham fisted rider, but agree, trail braking might be a bit of a challenge at first. The clip-ons look like they will be next in the queue for purchase.

Because the ABS system is connected to all the other electronic aids my information was you cant eliminate it or remove it like the previous models.

With callipers I had the GP Rx ones which have 4 x 32mm pistons and was told this would effect the way the std ABS modulates when trying to do its job. I guess the ABS is valved to move fluid for 4 x 30mm pistons which is less than whats required to move the 4 x 32 ones so wouldn't work the same way.

If you change callipers to the same amount of pistons and size (ie volume of fluid moved) thats not an issue.

On the master cylinder side changing the size of the bore and stroke doesn't effect the running of the ABS just the calculated feel in the ratio to the callipers and effectiveness of the brakes.

You can plug the ABS and not have an issue. And I’ve changed my calipers from 32 to 30 and don’t have an issue with the ABS working properly.

You can physically plug it of course on the v4 .. but it impacts on all the associated traction wheelie slide etc etc… to the point it is wrong to do it!
and your std stylema callipers are 30…

I have a v2. It comes with 32 standard. And plugging the abs does not effect any of the other aids. I’ve done it. The abs does not have anything to do with the traction control, wheelie control etc

So not a V4 then.....in the V4 forum section with the OP talking about his modifications to his V4?

If it helps then I had a modified 1098R engine in a 748R Frame with no ABS. The Gp callipers and 19RCS master cylinder worked fine on that too!:rolleyes:
 
I have a track v4r and an rcs 19 corsa corta sitting idle after taking off my hp4

I haven’t put it on the track v4r due to the concerns on this thread but I am going to give it a try to see how ‘wooden’ it really is. The 17 rcs corsa corta on my 1199 has good feel and adjustability. The thing I struggle with is that everyone who was using rcs was using rcs 19 on track bikes with 30mm pistons before brembo released the rcs 17!

My entire brake set up is off of a v4. It makes no difference what bike it’s currently on.. brakes are brakes

It’s doable. You get a lot of power with very little lever pull. The only thing I didn’t like was it’s a bit hard to trail the brakes. It felt very on or off.
 
It makes every difference!!
do you have full v4 loom/electronics too?
No.. it really doesn’t. The abs pump controls the abs. Slide, dtc, dwc etc, is controlled through power delivery, not the abs. You seem like the type of person that likes to argue just because you don’t know what you’re talking about… Both bikes use the Bosch ABS unit, Both bikes use a BBS unit to control the aids. Both bikes use the same wheel speed sensors. Both bikes employ similar logic control between ECU, BBS and peripheral sensors. If you remove the pump completely you will have issues. If you simply plug the port for the lines you’ll be fine.
