Remote Reservoir 4oz

The Wilwood remote reservoir 4oz master cylinder reservoir is an essential component for builders and enthusiasts upgrading to Wilwood combination or tandem remote master cylinders. This compact plastic reservoir stores brake fluid independently from the main master cylinder housing, allowing for cleaner engine bay layouts and custom brake system configurations. Remote reservoirs are crucial when installing modern hydraulic brake systems in custom builds, street rods, race cars, or any application where conventional integral master cylinder designs conflict with engine placement, turbocharger routing, or aesthetic preferences.

This 4-ounce capacity reservoir pairs directly with Wilwood combination and tandem remote master cylinders, maintaining consistent fluid pressure and volume regulation across brake circuits. The plastic construction is lightweight—weighing only 0.07 lbs—yet engineered to withstand thermal cycling and pressure fluctuations inherent to performance braking systems. The compact footprint (5.6 x 2.05 x 5.8 inches) enables flexible mounting in tight engine compartments, custom frame rails, or underbody locations. Wilwood reservoirs feature internal baffle design and proper fluid venting to prevent aeration and ensure stable brake pedal feel under repeated hard stops and fade-free modulation.

Professional builders, drag racers, and street rod fabricators rely on this remote reservoir when engineering fully integrated brake systems that demand reliability and precise fluid dynamics. It integrates seamlessly with Wilwood's full line of master cylinders and proportioning valves, ensuring OEM-quality pressure distribution and stopping power. Installation requires proper hard-line routing from the master cylinder and return lines, with mounting brackets or secure fastening to prevent movement during acceleration and braking events. Compatibility is confirmed with all Wilwood combination and tandem remote master cylinder models—verify your specific master cylinder part number before ordering to ensure proper fluid capacity matching.
