{"product_id":"3-4-internal-reservoir-master-cylinder","title":"3\/4\" Internal Reservoir Master Cylinder","description":"The GKTech FL-IR-34 is a stand-alone 3\/4\" internal reservoir master cylinder engineered for enhanced braking performance in motorsport and custom vehicle builds. Its robust construction includes a high-pressure die-cast aluminum body with a protective black E-coating, ensuring durability and longevity. Superior quality EPDM rubber seals are utilized for reliable operation.\n\nTested to SAE J1153_201202 standards, this master cylinder offers confidence in its safety and performance. It is compatible with standard DOT 3, DOT 4, and DOT 5.1 Glycol ether based brake fluids. The internal reservoir design simplifies installation, and the unit can be easily maintained or rebuilt using readily available kits. Key specifications include a 0.75\" bore size, 1.25\" stroke, 0.44 sq in area, and 0.55 cu in volume.\n\nThe FL-IR-34 master cylinder features a single outlet with a 3\/8-24 thread and a 5\/16-24 rod thread. The bolt spacing is 2-14\". Its SAE 45-degree flare outlet is designed to work with both inverted (single) and double flare brake lines. The FAQ section suggests that the 3\/4\" bore size provides a more direct, firmer lever feel with less throw required to lock the rear brakes, making it suitable for applications requiring more bite, such as those with larger brakes or wider tires (e.g., 235 width).\n\nGKTech backs this master cylinder with a lifetime warranty against manufacturing defects, highlighting their commitment to quality and customer satisfaction. The product is compatible with a wide range of Nissan, Infiniti, Scion, Subaru, and Toyota vehicles, including popular models like the S-chassis, R-chassis, Z-chassis, FR-S, BRZ, and GT86\/GR86.","brand":"GKTech","offers":[{"title":"Default Title","offer_id":52688559997240,"sku":"FL-IR-34","price":83.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/663689491.webp?v=1784891024","url":"https:\/\/store.motormia.co\/products\/3-4-internal-reservoir-master-cylinder","provider":"MOTORMIA","version":"1.0","type":"link"}
