Wilwood 260-11475 Compact Remote Master Cylinder Bore Banjo Outlet - RM5 3/4

The Wilwood 260-11475 is a compact remote flange-mount master cylinder featuring a 3/4" (0.750") bore and a 3/8-24 banjo-style fluid outlet, sold without reservoir. Part of Wilwood's proven RM5 series, this master cylinder is purpose-built for high-performance brake and hydraulic clutch applications where space is at a premium and dependable fluid delivery is critical.

Machined from high-pressure die-cast aluminum, the RM5 body measures just 3.37" from the mounting flange to the front of the cylinder, providing 2.16" of additional clearance between the mounting flange and the fluid outlet compared to full-size units — without sacrificing output capacity.

Key Features:

• 3/4" (0.750") bore for responsive pedal feel with fast hydraulic action
• 1.12" piston stroke — meets or exceeds the stroke capacity of most full-size master cylinders
• 3/8-24 banjo fluid outlet port located at the top radius of the bore to minimize trapped air
• Ultra-short 3.37" compact body designed for tight-clearance installations
• Fluid inlet port tapped with 11/16-20 internal threads for direct or remote reservoir mounting
• Black E-coat finish on die-cast aluminum body for corrosion resistance and long-lasting durability
• Fully rebuildable construction
• Sold without reservoir — compatible with Wilwood 4 oz., 7 oz., or 10 oz. reservoir kits (sold separately)

The banjo outlet design allows for low-profile brake line routing in confined engine bays, chassis tunnels, or custom fabrication scenarios. The 3/4" bore delivers a heavier pedal feel with quicker, more direct hydraulic response — well-suited for brake actuation, hydraulic clutch, and other high-demand hydraulic systems. Compatible with Wilwood's full range of reservoir and fitting accessories.
