Constructed from corrosion-resistant aluminum and finished in silver and black, the assemblies are built for trailer environments where saltwater exposure, vibration, and frequent loading demand durable components. The package includes one left and one right cylinder, each with its link arm, providing a convenient swap that restores brake actuation symmetry and performance.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these uni-servo cylinders fit my 10\" and 12\" trailer brakes?\u003c\/h3\u003e\n\u003cp\u003eThe telfair cylinders are designed to match the mounting and actuation geometry used on many 10\"x2-1\/4\" and 12\"x2 marine hydraulic drum brakes.
