14 mm Front Brake Master Cylinder - CSC Cross-Model Application

Hydraulic front-brake master cylinder cataloged with a 14 mm piston diameter. The exact Zongshen manufacturer number appears under multiple CSC inventory SKUs, making this one of the stronger CSC cross-references.

CSC Cross-Reference

  • Z440-113: RX4
  • R18-113: RE3 / SG400
  • XE23-101: RX1E
  • Zongshen MPN: 53008-R1L1-000001
  • Piston Diameter: 14 mm

For custom motorcycle use, piston bore is only one compatibility point. Compare handlebar clamp diameter, mounting orientation, lever geometry, reservoir connection and brake-hose/banjo fitting before installation.
