Product Description
Front Brake Master Cylinder Assembly for CSC RX4 and SG400 / RE3
Restore smooth, dependable front-brake control with a factory-spec replacement for your CSC RX4 or SG400 / RE3. CSC part Z440-113 uses Zongshen OEM number 53008-R1L1-000001 and comes as a complete right-hand control assembly rather than just a bare pump.
The assembly includes the 14 mm front brake master cylinder, integrated fluid reservoir, black adjustable-reach brake lever, 22 mm handlebar clamp/perch, right-side mirror mount and 2-pin front brake-light switch. It is a convenient replacement for a leaking, sticking, damaged or worn original master cylinder.

OEM Cross-Reference Information
The same 53008-R1L1-000001 master-cylinder number is also cataloged for the CSC RX1E. The RX1E uses a different brake-lever part number, so complete-assembly interchange should be compared before installation.
This master-cylinder family is also documented on Zongshen-derived motorcycles including the SM Sport SM3 400 / Cyclone RE3 family and Victory Venom 400. Some applications use a different lever configuration, so use the OEM number and specifications above when comparing non-CSC applications.
What's included: One complete right-hand front brake master-cylinder assembly as shown, including reservoir, adjustable lever, handlebar clamp and 2-pin brake-light switch.
