F// 4000
Robust. Safe. Modular.
// The master cylinder
Our F//4000 master cylinder is the result of precise, thorough development work and extensive know-how. It can be used modularly, is suitable for single and dual brake systems, and can be equipped with an additional lever for mechanical parking brakes and a brake signal switch. A specially developed system (SBP) allows our brake system to be bled quickly and easily, and thanks to the generous oil reservoir, the master cylinder provides a constant pressure point, right up to the brake pad wear limit. The forged aluminum and fiber-reinforced injection-molded components are absolutely reliable, safe, robust, and resilient.

// Highlights
SBP
Our patented and intelligent filling and bleeding system, "Smart Bleed Port," or SBP for short, simplifies servicing. After opening the screw plug half a turn, the brake system can be easily bled without the need for a syringe.
Two-piece clamp
To simplify installation and service, the master cylinder comes with a two-part clamp.
Optional parking brake
The two-part clamp is used to connect the lever we developed for controlling a mechanical parking brake. The lever is designed to be within the driver's reach, preventing the vehicle from moving without releasing the parking brake.
Brake signal switch
An adjustable brake signal switch can also be optionally screwed onto our master cylinder.
Modular lever bearing
Our brake lever allows single and dual operation by simply changing the bearing position.
Ergonomic lever with ball end
The ergonomic 4-finger lever covers a wide range of grip widths and enables high braking power with minimal hand force. Finished with a ball end, it offers maximum safety. The fiber-reinforced composite material provides consistent comfort in all weather conditions. A predetermined breaking point has been integrated into the design for optimal emergency running properties.
Shortenable hose
The hose of our brake system can be shortened as required using a screwed connection on the master cylinder and the caliper, allowing it to be optimally adapted to any vehicle.

// The caliper
Our master cylinders and calipers are designed for both left- and right-hand mounting and provide sufficient force to safely brake even heavy cargo bikes and LEVs. The caliper piston is generously dimensioned and ensures perfect transmission of braking force to the disc. An integrated offset in the caliper reduces the variety of adapters. The top-load function and the post-mount system improve ease of service.

// Highlights
Magnetic pad holder
Magnets are integrated into the stainless steel pistons for optimal positioning of the brake pads. These also allow for easy pad replacement.
Pad stop
We've integrated a brake pad stop into our caliper. This allows the brake pad to be changed from above without it falling through.
Adapter
The integrated offset in the caliper and the post-mount standard reduce the need for complicated adapters. Our adapters cover a wide range of IS-2000 and post-mount mounts on the vehicle.
Shortenable hose
The cable of our master cylinder can be shortened as required using a screwed connection on the master cylinder and the caliper, allowing it to be optimally adapted to any vehicle.
Fahrwerker splitter
Our splitter is designed to control a dual system with a single master cylinder. Equipped with a service port for bleeding and two mounting holes, it offers maximum flexibility and ensures perfect distribution thanks to any connection direction and orientation.
