Fixed Seal Master Cylinder
The Fixed Seal (FS) Master Cylinder enables a range of applications with diameters from ø20.64 mm up to ø26.99 mm, and strokes from 31 mm up to 52 mm. The mounting distances are able to cover the European standards 90 or 101.8 mm under 45°, as well as the Japanese standards 80x60 or 80 mm under 0°, considering installation angles from 0° to 30° upwards.
The naming of the FS Master Cylinder reflects a design characteristic of this product. The seals in charge of isolating the brake fluid in two different circuits are located in the Master Cylinder housing, not on the MC Plungers (Compact Master Cylinder Design). In this way, the design can be optimized regarding space and provides a shorter overhang of the Master Cylinder being mounted into the booster. Therefore, this design characteristic enables a more compact installation packaging. The FS design has fewer components, which positively impacts cost and quality.
