Designed for heavy-duty automotive and industrial applications, this high-volume aluminum master cylinder features a durable die-cast aluminum body that ensures reliable performance under demanding conditions. With a fluid capacity of 8.2 ounces, it provides at least 26% more fluid volume than comparable models, reducing the risk of fluid starvation during extended or high-intensity use. The 1-7/16 inch piston travel offers ample margin for large piston calipers, ensuring consistent brake modulation and pedal feel. Heavy-duty internal springs facilitate quick retraction, supporting rapid brake release and overall system responsiveness. The formed steel lid with a bellows-type gasket seals out moisture and contaminants, maintaining optimal fluid integrity. Common dimensions for flange or side mounting and a 1/8-27 NPT outlet port make installation straightforward across a wide range of vehicles and equipment, ensuring versatility and compatibility. This master cylinder is built to withstand the rigors of fleet operations and industrial machinery, making it an ideal choice for demanding heavy-duty brake systems.
