Bottles (6-Pack) — Low-Hygroscopic, High-Temp Protection","description":"\u003cp\u003e\u003cstrong\u003eJohnsen's 7012 Silicone DOT 5 brake fluid is a silicone-based, low-hygroscopic hydraulic fluid sold in 12 oz. bottles (pack of 6) for drum and disc brake systems that are not ABS-equipped.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eThis silicone DOT 5 formulation was developed to resist water absorption and maintain stable performance under high temperatures. Unlike glycol-based DOT 3 and DOT 4 fluids, silicone DOT 5 absorbs very little moisture, which can reduce corrosion and fluid degradation in appropriate applications. The product is intended for classic cars, custom builds, racecraft where silicone fluid is specified, and other brake systems that explicitly accept DOT 5 — it should not be used in ABS-equipped vehicles.\u003c\/p\u003e\n\n\u003ch3\u003eHow does Johnsen's DOT 5 differ from conventional brake fluids?\u003c\/h3\u003e\n\u003cp\u003eJohnsen's DOT 5 uses a silicone base rather than glycol-ether. That chemical difference means it takes up far less water, and it remains less prone to internal corrosion when kept sealed and used in systems compatible with silicone fluid.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eSilicone-based, not glycol-based\u003c\/li\u003e\n  \u003cli\u003eEssentially non-hygroscopic — absorbs under 1% water by weight\u003c\/li\u003e\n  \u003cli\u003eLower tendency to corrode brake system metals when dry\u003c\/li\u003e\n  \u003cli\u003eMaintains performance at high temperatures (500°F protection listed)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCan I use this fluid in my ABS-equipped car?\u003c\/h3\u003e\n\u003cp\u003eNo — Johnsen's 7012 DOT 5 is specifically not recommended for ABS systems. ABS components and modern braking systems are typically designed for DOT 3, DOT 4, or DOT 5.1 glycol fluids, which have different compressibility and compatibility characteristics.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eDo not use in ABS or anti-lock brake systems\u003c\/li\u003e\n  \u003cli\u003eUse only in systems explicitly allowing DOT 5 silicone fluid\u003c\/li\u003e\n  \u003cli\u003eCheck vehicle manufacturer or service manual before switching\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat maintenance or handling should I follow when using silicone DOT 5?\u003c\/h3\u003e\n\u003cp\u003eBecause silicone DOT 5 is less hygroscopic, it doesn’t require as-frequent replacement purely for moisture control, but careful handling is still important. Keep bottles sealed, avoid mixing with glycol fluids, and flush the system completely if converting from another fluid type.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eStore bottles tightly sealed and away from heat\u003c\/li\u003e\n  \u003cli\u003eFlush system thoroughly before switching fluid types\u003c\/li\u003e\n  \u003cli\u003eAvoid mixing silicone DOT 5 with DOT 3\/4\/5.1 glycol fluids\u003c\/li\u003e\n  \u003cli\u003eFollow recommended service intervals for your vehicle and usage\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat performance benefits does this product provide?\u003c\/h3\u003e\n\u003cp\u003eJohnsen's 7012 offers high-temperature protection and stable brake performance when used in compatible systems. Its low moisture uptake helps slow internal fluid breakdown and reduces the risk of boil-related issues under heavy or sustained braking, provided the system is designed for silicone fluid.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eRated for high-heat protection (500°F listed)\u003c\/li\u003e\n  \u003cli\u003eReduced moisture absorption versus glycol fluids\u003c\/li\u003e\n  \u003cli\u003eGood choice for vintage cars, show vehicles, and certain race applications\u003c\/li\u003e\n  \u003cli\u003eSold as six 12 oz. bottles for multi-vehicle servicing or spare supply\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for: Johnsen's 7012 Silicone DOT 5 Brake Fluid is best suited for owners and mechanics of classic cars, custom builds, and specialty vehicles that specify silicone DOT 5. It appeals to restorers and enthusiasts who want a low-humidity-absorbing brake fluid and those servicing multiple vehicles or preparing a vehicle for track days where DOT 5 is acceptable. Do not buy this product for modern cars with ABS or for systems that require glycol-based fluids; always confirm compatibility before use.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Is Johnsen's DOT 5 brake fluid suitable for ABS systems?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No. This silicone DOT 5 fluid is not recommended for ABS-equipped systems; use DOT 3\/4\/5.1 if ABS is specified.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can I mix this silicone DOT 5 with DOT 3 or DOT 4?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No. Silicone DOT 5 must not be mixed with glycol-based DOT 3 or DOT 4; flush the system before converting.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Johnsen's","offers":[{"title":"Default Title","offer_id":67585714520249,"sku":"B00C8720S8","price":169.38,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0822\/3765\/3177\/files\/johnsens-dot5-12oz-front-label.jpg?v=1790476614","url":"https:\/\/redleafauto.ca\/products\/johnsens-silicone-dot-5-brake-fluid-12-oz-bottles-6-pack-low-hygroscopic-high-temp-protection","provider":"Redleaf Auto","version":"1.0","type":"link"}
