The EMPI 16-2531-0 is a complete hydraulic dual master-cylinder pedal assembly with integrated throttle pedal — a full pedal cluster purpose-built for custom VW-based chassis. The clutch circuit uses a 3\/4\" bore master cylinder and the brake circuit uses a 7\/8\" bore, with 1\/8\" NPT ports on both. Mount it to your firewall, plumb it in, and you have a complete hydraulic clutch and brake pedal system built from scratch rather than adapted from factory parts.\u003c\/p\u003e\u003ch3\u003eWhat's Included\u003c\/h3\u003e\u003cp\u003eOne (1) complete dual master cylinder pedal assembly with throttle pedal — EMPI 16-2531-0\u003c\/p\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eYears\u003c\/th\u003e\n\u003cth\u003eVehicle\u003c\/th\u003e\n\u003cth\u003eNotes\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eAll years\u003c\/td\u003e\n\u003ctd\u003eVW-based dune buggy\u003c\/td\u003e\n\u003ctd\u003eFirewall-mount pedal cluster for custom chassis; confirm bore sizes suit your system\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAll years\u003c\/td\u003e\n\u003ctd\u003eSand rail, kit car, Baja bug\u003c\/td\u003e\n\u003ctd\u003eFor hydraulic clutch and brake plumbing in custom builds\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAll years\u003c\/td\u003e\n\u003ctd\u003eCustom shortened VW Beetle pan\u003c\/td\u003e\n\u003ctd\u003eHydraulic clutch conversion builds using firewall-mount pedal cluster\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch3\u003eFeatures \u0026amp; Benefits\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eComplete pedal cluster — clutch, brake, and throttle pedals in one assembly\u003c\/li\u003e\n\u003cli\u003eHydraulic clutch circuit — 3\/4\" bore master cylinder for precise, consistent clutch actuation\u003c\/li\u003e\n\u003cli\u003eHydraulic brake circuit — 7\/8\" bore master cylinder, appropriate for most disc and drum hydraulic setups\u003c\/li\u003e\n\u003cli\u003e1\/8\" NPT outlets on both circuits — accepts standard brake line fittings\u003c\/li\u003e\n\u003cli\u003eFirewall-mount design — clean integration into custom chassis\u003c\/li\u003e\n\u003cli\u003eSaves significant fabrication time vs. building a pedal box from scratch with individual components\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpec\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart number\u003c\/td\u003e\n\u003ctd\u003e16-2531-0\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eEMPI\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eClutch bore\u003c\/td\u003e\n\u003ctd\u003e3\/4\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrake bore\u003c\/td\u003e\n\u003ctd\u003e7\/8\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFittings\u003c\/td\u003e\n\u003ctd\u003e1\/8\" NPT\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePedals\u003c\/td\u003e\n\u003ctd\u003eClutch, brake, throttle\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplication\u003c\/td\u003e\n\u003ctd\u003eCustom chassis, dune buggy, sand rail, kit car\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSold\u003c\/td\u003e\n\u003ctd\u003eEach (complete assembly)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch3\u003eInstallation Notes\u003c\/h3\u003e\u003cp\u003eMount to a custom firewall or pedal box frame. Confirm that the 3\/4\" clutch bore and 7\/8\" brake bore produce appropriate pedal effort and hydraulic pressure ratio for your specific system before ordering. Run separate brake lines from the 1\/8\" NPT ports on each circuit. This assembly requires a compatible hydraulic clutch slave cylinder already sized for a 3\/4\" bore master.
