The Wilwood High Volume Aluminum Master Cylinder (1.00" Bore) is designed for high demand brake systems that require maximum fluid capacity, long piston travel, and consistent pedal feel, especially when paired with large multi-piston calipers. Built from high pressure die-cast, high grade aluminum, this master cylinder delivers excellent heat dissipation, tight bore tolerances, and long seal life.
Featuring an 8.2 oz integral reservoir, it provides significantly more fluid capacity than most competing integral-reservoir designs, helping maintain cooler operating temperatures and fluid reserve during extended braking events or high pad wear conditions. The 1.43" piston stroke offers extra margin for high displacement caliper setups, while heavy duty internal return springs promote fast retraction and improved pedal response. A formed steel lid with a bellows-style gasket keeps moisture out while maintaining proper pressure balance.

Tech Insight
The 1.00"bore high-volume master cylinder offers increased fluid displacement per stroke, making it a strong choice for systems with higher total caliper piston area. Wilwoods die-cast aluminum construction eliminates the need for stainless sleeves found in sand-cast designs, improving heat dissipation and seal longevity. The internal slosh baffle ensures uninterrupted fluid supply during hard braking, acceleration, and corneringcritical for off-road and competition environments.
