Product Details

Brembo 19RCS Brake Master Cylinder

The Brembo 19RCS Master Cylinder is optimized for dual-caliper, four-piston braking systems. It utilizes a massive 19mm piston that provides the maximum amount of stopping power possible.

The Brembo RCS Brake Master Cylinder allows the rider to choose between more power or more precision to best complement their riding style, track/street conditions and other brake components. The unique design of the RCS system offers the flexibility to change the brake lever ratio at the turn of a screw. The 20mm setting provides a more reactive braking response and the 18mm setting allows for better feel and modulation. Additionally, the Brembo lever features an adjustable thumb screw that can be customized to fit a range of riders’ hands. In the event of a crash the outer portion of the lever folds up and away to avoid damage. The patented master cylinder is constructed of forged aluminum and then CNC machined down to remove any excess weight. All of its components, including the piston, seals and pushrod, are the same as those used in MotoGP and WSBK.

Better performance over stock
S1000RR, looks great better bite and looks awesome. It’s a little bit of a pain to install because there’s no room for the reservoir. You will need to buy the reservoir with this product and use both washers and mount it to the top slot an she will have clearance.

hi all is this item will fit my zx14r 2012 non abs?
Hameed A on Feb 12, 2017
Will this work with a brembo p32f caliper? For a Honda grom.
A shopper on Jan 19, 2017
BEST ANSWER: Why are you putting this on a grom?
Will I need a new reservoir ?
Natalie B on Nov 12, 2018
BEST ANSWER: Yes your going to need a reservoir and a mount for it . I got the Rizoma Wave and the Rizoma CT451B mounting bracket. Looks really good. I also added the Brembo Bar Clamp with Mirror Perch. My Suzuki fit like it was made for it.
Was wondering if my OEM brake lines on my 07 cbr600rr mount up to this Master cylinder or if new brake lines need to be purchased? Thanks.
Cameron M on Aug 27, 2018
BEST ANSWER: They should line up, maybe with some slighht repositioning. I would suggest all new kevlar/steel lines to maximize the master cylinder. Mine are used on a Ducati project bike, so I went with the Duc 848 lines.
Not a hundred percent sure if this fits a 2016 panigale 1299s. Do you guys know?
