Brembo 15RCS (Premium Brake Kit)[110.A263.30 + 110.A263.85]
The Brembo 15RCS Premium Kit - Brembo 15RCS Radial Master Cylinder + Bracket & Reservoir Mounting Kit
This premium kit includes the following: Brembo 15RCS Radial Master Cylinder, including 1 Micro-switch and 1 x double banjo bolt (M10x1mm for double banjo lines). Bracket & Reservoir Mounting Kit: 45cc Reservoir, Reservoir Bracket, Brake Fluid Hose with clamps, fixing hardware (as shown in the picture).
The 15RCS brake master cylinder is intended specifically for Naked and SuperMotard machines, the 15RCS master cylinder has all the technological features of the 19RCS - the M/C most popular with enthusiast - namely the Ratio Click System, the same component specifications as for MotoGP system, hard-anodized cylinder body, and folding lever. With the 15RCS, the user can change the lever pivot distance from 18mm to 20mm simply by turning the adjuster inside the cylinder. This brake M/C can be matched with the 16RCS clutch master cylinder, giving a set-up that will deliver MotoGP performance, as well as being a real attention-grabber.
19RCS , 17RCS, 15RCS, 14RCS ? These numbers identify piston diameter:
19RCS to be installed on twin disks bikes with axial or radial calipers but NOT on Floating Calipers
17RCS to be installed on twin disks bikes with axial or radial calipers whose pistons diameter is 32mm or lower, but NOT on Floating Calipers; for example Ducati Panigale or RSV4, Yamaha R6 etc etc.
15RCS to be used on twin disks braking system carrying floating calipers (Naked), and on single disk bikes (motard).
The 15 RCS with 15 x 20 set up works like a 16 x 18 mc, while 15 x 18 equals a 16 x 16 mc.
14RCS to be installed on single/twin disks Scooters and single disks Motorcycles (from 50cc up to 600cc) Available both Right and Left Side.
Adjustable ratio: RCS system
This new patented device allows to modify the pump lever ratio on two values, 18 or 20 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 the different characteristics of the braking system, of the usage and driving, such as, for ex., the wet or dry conditions, asphalt with more or less grip, circuit with strong braking.
This adjustment is the element missing till now to get the ideal feeling among the rider, the driving style, the bike and the circuit.
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.
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
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 brake 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.
A special housing has been designed for the rear stop light mechanic micro switch, for street usage of the master cylinder. The micro-switch is supplied in the same master cylinder package.
The switch works "normally open" when the lever rests; by pressing the lever it closes the circuit. The switch can not replace a switch that works "normally closed", such as BMW switches. You can purchase optional switch available in the linked products.
Lever contrast springs
High load springs have been chosen to guarantee the constant contact between the eccentric drive and the push rod; in this way you can avoid wear due to the knocking by the vibrations of the vehicle and an item of further safety is introduced in the transient phase between accelerator release and brake, resulting in an advantageous life increase of the various components.
Fits a M10x1,0 mm bajo adapter (normaly japan bikes has M10x1,25mm one).
OEM axial master cylinder brakes hoses could not fit radial mc, we can supply specific brake hoses or the adapter.
