The internal residual valve maintains system pressure where needed for drum or mixed brake setups, and the compact, universal footprint suits many dune buggy frames and mounting arrangements. Built to replace or upgrade existing small-bore units, it gives improved fluid volume and smoother pedal feel for light off-road vehicles.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the 22mm bore affect braking performance?\u003c\/h3\u003e\n\u003cp\u003eA 22mm bore increases fluid displacement per pedal stroke compared with smaller diameters, which helps move more brake fluid toward calipers or wheel cylinders and can deliver firmer response in light vehicle applications. It’s particularly useful when converting a single-circuit setup to a dual or when you need enough capacity for 2- or 4-wheel braking without oversizing.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e22mm bore for higher fluid displacement and consistent pedal travel\u003c\/li\u003e\n  \u003cli\u003eBetter suited than small-bore units for light off-road brake systems\u003c\/li\u003e\n  \u003cli\u003eBalances volume and required pedal force for dune buggy weight\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat components are included and why do they matter?\u003c\/h3\u003e\n\u003cp\u003eThis EMPI master cylinder ships complete with the transparent reservoir, screw-on cap and an internal residual valve already installed. That means fewer parts to source separately and a faster installation, while the residual valve preserves a small amount of pressure needed for drum brakes or mixed braking systems to function correctly.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eReservoir and cap included for immediate fluid fill and sealing\u003c\/li\u003e\n  \u003cli\u003eInternal residual valve preinstalled to maintain proper system pressure\u003c\/li\u003e\n  \u003cli\u003eReady-to-mount assembly reduces installation time\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill this fit my dune buggy or vintage VW-based project?\u003c\/h3\u003e\n\u003cp\u003eThe master cylinder’s mounting pattern and port layout are common to many lightweight off-road and kit vehicles, but exact fitment depends on your pedal box and brake line routing. Check spline\/rod length, mounting bolt spacing and port thread sizes before ordering to ensure direct replacement or minimal modification.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eCommon universal footprint for many buggies and kit cars\u003c\/li\u003e\n  \u003cli\u003eVerify push-rod length and mounting bolt centers for compatibility\u003c\/li\u003e\n  \u003cli\u003eMay need adapters or custom lines for some vintage conversions\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow do I install and maintain the unit safely?\u003c\/h3\u003e\n\u003cp\u003eInstallation requires basic mechanical skills: secure the cylinder to the pedal assembly, connect brake lines to the correct ports, fill with recommended brake fluid, then properly bleed the system to remove air. Regular checks of fluid level and cap sealing keep performance reliable and prevent contamination.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eBolt to pedal box and attach push rod with correct clearance\u003c\/li\u003e\n  \u003cli\u003eUse manufacturer-recommended brake fluid and follow bleeding steps\u003c\/li\u003e\n  \u003cli\u003eInspect reservoir cap and seals periodically for leaks or debris\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for? EMPI’s 22mm Buggy Master Cylinder is aimed at dune buggy builders, kit car enthusiasts, and owners of light off-road vehicles who need a compact, higher-volume master cylinder with an onboard reservoir and residual valve. It’s a practical upgrade for projects that require reliable 2- or 4-wheel braking capacity without converting to a much larger industrial master cylinder. Mechanics and hobbyists who can verify mounting and port compatibility will find this unit an efficient way to refresh or improve braking control on lightweight recreational vehicles.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Does this master cylinder work for both 2- and 4-wheel brake systems?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes.
