Designed for heavy-duty applications, this aluminum master cylinder offers exceptional fluid capacity and reliability for industrial equipment and automotive fleet systems. Its high-pressure die-cast aluminum body ensures durability while maintaining a lightweight profile. The internal design features a high-volume reservoir with a capacity of 8.2 ounces, providing at least 26% more fluid volume than comparable models, reducing the need for frequent refills during extensive operation. The 1-7/16″ piston travel offers extra margin for large piston calipers, ensuring consistent braking performance under demanding conditions. Heavy-duty internal springs enable quick retraction, minimizing pedal travel and improving responsiveness, especially crucial in high-stress environments. Formed steel lids with bellows-style gaskets effectively seal out moisture and contaminants, protecting the internal fluid from environmental damage. This master cylinder uses standard flange or side-mount dimensions and is fitted with a 1/8-27 NPT outlet port, making it compatible with a wide range of brake systems and installations. Its robust construction and high fluid capacity make it suitable for both industrial machinery and heavy-duty automotive applications where reliability and performance are paramount.
