{"product_id":"13-16-inch-bore-master-cylinder","title":"13\/16-inch Bore Master Cylinder","description":"By increasing the internal cylinder diameter from the OEM 3\/4 inch (19.055mm) to 13\/16 inch (20.54mm), this unit reduces pedal pressure by 14% and improves half-clutch operating characteristics. It is specifically intended for use with pull-type clutch configurations, providing proper engagement positioning.\n\nInstallation requires specific care to maintain performance. Because the cylinder stroke volume is reduced compared to the standard part, adjustments to the stroke are often necessary. Users must ensure that no air enters the system during installation; clamping the hose securely is required before removing the old cylinder. It is recommended to fill the cylinder with brake fluid and bleed it thoroughly before final connection. Vacuum pressure is suggested for complete air removal, particularly when using wide-diameter pipes such as the U-pipe; using a U-pipe eliminator adaptor is recommended for this purpose. A copper seal washer (Genuine Nissan part 46237-A4600) is required for installation.","brand":"Nismo","offers":[{"title":"Default Title","offer_id":52663118397752,"sku":"30620-RSR40","price":216.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687515586.jpg?v=1784323983","url":"https:\/\/store.motormia.co\/products\/13-16-inch-bore-master-cylinder","provider":"MOTORMIA","version":"1.0","type":"link"}
