RCB S1 Master Brake Pump

S1 Master Brake Pump – Strong. Powerful. Ergonomic. A Mastercraft.

Introducing the S1 Master Brake Pump, featuring the sophisticated Radial Master Cylinder—designed to enhance rider response through its rigidity while improving power delivery efficiency.

The transparent fluid container offers a convenient system, ensuring that enough brake fluid is readily available for use and future refills.

Engineered with rider ergonomics in mind, the folding lever can turn up to 90 degrees, preventing further damage in the event of a crash. Additionally, the safety grooves at the edge of the lever help reduce damage to the brake pump during collisions.

For added customization, the Lever Adjuster allows for a personalized setup, improving the feedback between the rider and the machine.

The anodization process gives the S1 Master Brake Pump exceptional resistance to corrosion and abrasion, ensuring long-lasting durability.

Designed for universal compatibility, it is available in two piston sizes:

• 14mm, suitable for single and double-piston calipers.
• 17mm, ideal for 4-piston calipers and above.

Produced through forging and CNC machining, the S1 Master Brake Pump is built for extreme rigidity and durability, giving you the confidence you need on the road.
