Brembo Brake Master Cylinder 19x18/19x20 RCS


By Brembo
Price: $290.00
Product ID : Brembo-MC-110.A263.10


Since the Brembo master cyl. uses a 6mm fluid inlet most all bikes require you get a new reservoir like the Evotech billet reservoir we sell.  If you would like to add it to the Brembo master cyl please shoot us an email or give us a call.  Thank you.

This new patented device allows to modify the pump lever ratio on two values, 19x18 or 19x20 mm, by simply rotation of the eccentric drive placed on the front of the lever drive. By the RCS system – Ratio Click System

 – it is very easy to pass from one configuration to the other one, modifying the lever ratio to adjust it to reach a different feeling.      

MotoGP Floating Piston

The inner piston, seals, push rod are the same as the majority of the MotoGP and SBK riders use , with very reduced manufacturing tolerances and of the very good smoothness.

Master cylinder body

The master cylinder body is in aluminium alloy, produced by forging and then CNC (Computer Numerical Control) machined by lightening milling.

Very closed manufacturing tolerances, similar to those used in MotoGP, guarantee the perfect matching with the floating piston due to a working precision never seen. For the superficial finishing it has been chosen the hard anodizing, electrolytic process which converts the surface of aluminium and its alloys into a vary hard oxide coating which guarantees very high resistance to abrasion and corrosion.

Brake lever
The lever is made of two main components: the racing lever drive and the lever itself, folding and manufactured by forging. In the lever joint it has been inserted a patented system which allows the rotation only by the effect of an eventual tumble of the bike, without the possibility of an accidental rotation and getting in this way a bigger dynamic safety.

The control for the lever distance adjustment from the handlebar has been re-placed and now it is in axis with the lever itself, guaranteeing the assembly of the eventual remote adjuster.

By using this control, the press push rod does not move in respect to the master cylinder body, keeping the best working angle of the push rod. Therefore, either by getting the clutch lever closer or farer to the handlebar, the efficiency of the kinematics motion does not change, assuring less friction and lack of scattered forces.

In addition the lever has its fulcrum on the pump body by mean of a bushing/gauged pin system which guarantees high stiffness and better feeling together with a high resistance to wear.

Brembo RCS is awesome
First let me explain how hard it was to understand what this MC real does. This MC was a great investment and will improve the feel and power of your brakes without a doubt. The MC looks beautiful as well and the included brake fluid reservoir finished the job nicely. The 19x18 gives the most feel while trail braking (it gradually increases in power). The 19x20 setting may be best for non trail brakers and street use. Also, it doesn't matter if you have 6 or 4 piston brake, your bike is going to stop better and most importantly, safer.

Most vital part on my bike!
The RCS19 master cylinder has got to be one of the most vital parts on my race bike. I have an 09 GSXR 750 I use strictly for racing and this addition is one of the most confidence inspiring parts that enables me to push my limits and have the confidence to brake deep. The fact that you can adjust the pressure from instant to more of a modulated feel helps a ton. I have the setting between the 18 & 20.

I am able to brake very deep into a corner with great feel. The stock master cylinder does not of this amount of feel. The RCS 19 has also saved me in incidents where I am running into a corner and the rider in front of me checks up and I am able to apply that ever so light amount of pressure which makes the difference of running into their wheel wheel or completing the turn.

Great product! Completely changes the feel of the brakes. One of the best upgrades I did on my track bike.
