{"product_id":"8-dual-black-firewall-brake-booster-and-wilwood-master-cylinder-kit","title":"8\" Dual Black Firewall Brake Booster and Wilwood Master Cylinder Kit","description":"The Classic Performance Products (CPP) 8 in Dual Black Firewall Brake Booster and Wilwood Master Cylinder Kit, Part Number 6474BB8DB-WWMCB, is engineered to significantly upgrade the braking system in classic vehicles.\n\nThis comprehensive kit includes an 8-inch black dual diaphragm firewall-mounted brake booster, which provides substantially more assist than single diaphragm units. This enhanced assist is particularly beneficial for vehicles undergoing front disc brake conversions or those equipped with larger brake systems. The booster's compact 8-inch diameter ensures adequate clearance within tight engine bays, delivering strong and consistent brake assistance.\n\nPaired with the booster is a black aluminum Wilwood master cylinder featuring a 1.125-inch bore. This master cylinder is known for its lightweight, high-performance design and is an excellent match for a variety of aftermarket disc brake configurations. The kit is intentionally supplied without a proportioning valve, offering flexibility for custom brake setups. For systems that require a proportioning valve, part number 260-13190 is recommended.\n\nThis kit is compatible with 1964-1972 A-Body, 1967-1969 F-Body, and 1968-1974 X-Body vehicle platforms. It is designed to work with 2-wheel disc, 4-wheel disc, and 4-wheel drum brake systems, and includes necessary hardware, a brake pedal extension rod, and a bleeder kit for a complete installation.","brand":"Classic","offers":[{"title":"Default Title","offer_id":52687395291448,"sku":"6474BB8DB-WWMCB","price":454.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/661176511.jpg?v=1784883637","url":"https:\/\/store.motormia.co\/products\/8-dual-black-firewall-brake-booster-and-wilwood-master-cylinder-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
