I would do brake upgrades in this order, based upon how big of change each can produce in my experience:
1) Pads
2) Master cylinder
3) Calipers
4) Rotors
Also, if it's a track-only/race bike, bypassing the ABS with a new set of brake lines and plugging the ABS pump can give you increased precision/feel.
the M50 calipers are really fantastic,
Look to change the pads, if you want a bit more feel get the RCS master cylinder.
I would leave the rotors till they are used and then upgrade to the Brembo WSBK.
I ride track at a good expert pace. Thanks for the advice guys. I've done pads so far.
Will the gp master work with the oem calipers? What would be the best ratio? 19 by 18 or 19 by 16? Is the rcs for the street? My bike will never see a public road.
With the stock M50 calipers on the 1199/1299, you need the Brembo 17RCS master, that's the one specifically made for those calipers.
There has been a lot of talk and different threads on the subject of how the rcs 17 is the cats pajamas when using m50s. I used it for almost a full race season before I gave up on it. Even after removing the abs it was spongy as hell. It would also get bad brake fade even in a 6 lap race.
I eventually ordered a cnc 19x18 with the intention of replacing the calipers if it didn't work out. It was awesome. The feel and feedback as well as braking power is amazing. I trail brake as a habit and have never had an issue with not getting enough feedback. In fact, in my circle of racer friends that are running the Pani, every single one uses either a 19x18 or 19x20 with the m50's...
For what it's worth.
Oh sure I know plenty of people running 19mm masters with the M50 calipers, but I wouldn't RECOMMEND it since it goes against Brembo's own recommendations. When the Panigale first came out and I was at the vendor parts show talking with one of the guys from Brembo, and asked him about the M50 calipers and whether I could take my 19x20 master from my 1198S and use it on my 1199, he said "I wouldn't recommend that, wait for us to come out with the 17mm product, the 19mm product was not designed to work with the smaller-piston calipers and you will not get the same feel". So that's pretty much the extent of where I left it, I never actually tried the 17RCS myself.
There's a big difference in a "racing" master vs. the "street/performance" master, which all of the RCS products are "street/performance" products. I've used a 19x20 racing master exclusively for over 10 years now on every track/race bike I've had, for me it's the cat's meow. I agree with you for hard track use, the RCS will not give the firm lever and resistance to fade of a racing master. But it's still better than the stock master. You should try your cnc master with different calipers at some point, you might not know what you're missing. I'm using the GP-4RX calipers with the billet 19x20 master and it's pretty much nirvana. Of course braking "feel" is highly subjective, so what feels fine/great to one rider might feel like garabage to another. Some people who ride my bike hate my brakes because they're too powerful. I've trained myself to use a light touch on the brakes, so I like them.
What's the difference performance wise between the standard gp and the billet version?
This thread is 2 years old so Im hoping I get a response. Im looking to upgrade the master cylinder on my 2015 1299. Right now I have CNC racing adjustable levers. If I bought any of the Brembo brake master cylinders would I be able to use them on the Brembo master cylinder.
That being said. What be a good option for me for 7 to 10 track days a year and the rest street riding? The Brembo 19x18 radial brake master cylinder , 19RCS Corsa or 17RCS Corsa?
No you won't be able to use your levers with any of the Brembo racing master cylinders. You'll need the 17RCS for that bike, it's the only one compatible with the stock calipers, and it still has a brake light switch on it so it will work on the street correctly.
Thanks for the information. Let me ask you this. If I wanted the 19x18 or 19RCS MC's what would be a good brembo caliper upgrade over the M50's that wouldnt break the bank. I do between 7-10 track days a season and the rest on the street. And regarding the MC's I mentioned do both have a brake light switch or just the 19RCS
