Brake cylinder can produce a thrust varying from the pressure of the brake cylinder and the piston size, and pass this thrust to the brake rigging by piston push rod. When the wagon releases, the brake cylinder with push-rod centering device helps the brake shoe to leave the wheel tread. 

MUB air brake system was developed according to UIC standard, and the technical parameters and interface sizes can meet the requirements of UIC standard, which makes sure that the vehicles mounting MUB air brake system can operate with the vehicles mounting other UIC standard brake system (eg. the vehicles installing Knorr or Wabtec brake system).

The MUB brake system is fully compliant with UIC standards and got the TSI certificate in 2013 and is on the ERA (Eu Railways) database.

MUB brake system has been used in Pakistan, Sudan, Myanmar and Gabon since 2009 with stable and good performance.

Furnished to suit the space and leverage requirements of locomotives, these cylinders differ from freight car brake cylinders primarily due to the wide variety of diameters available and shorter piston strokes.

• The push rod is pinned to the piston hollow rod for positive release of the shoe from the wheel when the piston retracts
• Wide variety of sizes and push rod configurations available to suit varied application requirements
