{"product_id":"8-5-brake-booster-upgrade-kit","title":"8.5\" Brake Booster Upgrade Kit","description":"The JDM Car Parts 8.5\" Brake Booster Upgrade Kit is engineered for the Datsun 240Z models from 1969 to 1972, providing a significant improvement in braking performance over the original 7-inch booster. It is compatible with the stock brake master cylinder with minimal modifications needed.\n\nThe kit includes a built-in check valve, though its location differs from the original, necessitating adjustments to vacuum hose length at both ends. A bypass connector is also provided to replace the original check valve. This upgrade is particularly beneficial for owners who have installed larger calipers, such as Toyota 4-pod calipers, which can cause wheel lock-up during hard braking. This booster upgrade allows for effective stopping power with reduced effort while maintaining the vehicle's stock appearance.\n\nMounting stud dimensions are center-to-center: 100mm on the long side and 70mm on the short side. For reference, the original 1969-1972 Datsun 240Z boosters have studs measuring 80mm on the long side and 70mm on the short side.\n\nCAUTION: This brake booster upgrade kit is NOT compatible with the original brake master cylinder found in 1969-1971 models. A late-type brake master cylinder (1972-1978), part number 24-J4232, is required for proper installation and function.","brand":"JDM Car Parts","offers":[{"title":"Default Title","offer_id":52688981066040,"sku":"24-J4501-V","price":499.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/664210441.webp?v=1784899722","url":"https:\/\/store.motormia.co\/products\/8-5-brake-booster-upgrade-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
