Unlike glycol-based DOT 3 and DOT 4 fluids, DOT 5 absorbs almost no moisture, which helps reduce corrosion and preserve brake responsiveness during storage or intermittent vehicle use. The product is sold in a six-pack of 12-ounce containers and provides thermal protection up to 500°F. Note: it is not compatible with ABS systems and should not be mixed with other brake fluid types.\u003c\/p\u003e\n\n\u003ch3\u003eWhy choose silicone DOT 5 over conventional brake fluids?\u003c\/h3\u003e\n\u003cp\u003eSilicone DOT 5 fluids are engineered to resist absorbing water from the environment, which keeps boiling points more consistent and reduces internal system corrosion over time. This can be beneficial for classic cars, stored vehicles, and some specialty applications where moisture control is important.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eEssentially non-hygroscopic — absorbs less than 1% water by weight\u003c\/li\u003e\n  \u003cli\u003eMaintains performance during long storage or low-use periods\u003c\/li\u003e\n  \u003cli\u003eHigher resistance to atmospheric moisture than DOT 3\/4\u003c\/li\u003e\n  \u003cli\u003eProvides thermal protection up to 500°F\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCan I use Johnsen's DOT 5 in my vehicle's ABS-equipped brakes?\u003c\/h3\u003e\n\u003cp\u003eNo — this silicone DOT 5 product is not intended for vehicles with ABS. ABS systems are designed around glycol-based fluids (DOT 3, DOT 4, DOT 5.1), and mixing or replacing those fluids with silicone DOT 5 can impair ABS function and introduce compatibility issues.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eDo not install in ABS or stability-control systems\u003c\/li\u003e\n  \u003cli\u003eDo not mix with DOT 3, DOT 4, or DOT 5.1 fluids\u003c\/li\u003e\n  \u003cli\u003eFlush and replace the entire system if switching fluid type\u003c\/li\u003e\n  \u003cli\u003eConsult the vehicle manufacturer before changing fluid chemistry\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow does this pack format benefit workshops and hobbyists?\u003c\/h3\u003e\n\u003cp\u003eThe six-bottle pack offers value and convenience for regular maintenance, multiple vehicles, or restoration projects.

Johnsen's Silicone DOT 5 12 oz. six-pack is aimed at classic car restorers, storage vehicle owners, small repair shops, and hobbyists who need a silicone-based brake fluid that resists moisture. If your vehicle’s manufacturer approves DOT 5 and the braking system is non-ABS, this product provides a practical, multi-bottle supply that reduces fluid exposure and helps maintain brake system integrity. Always follow vehicle manufacturer recommendations and professional service procedures when changing brake fluids.\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 compatible with ABS systems?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No. This silicone DOT 5 formulation is not for ABS-equipped systems and must not be used in vehicles requiring DOT 3\/4 or DOT 5.1.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can I mix this DOT 5 with DOT 3 or DOT 4 fluids?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No. Do not mix silicone DOT 5 with glycol-based DOT 3 or DOT 4 fluids; full system flush is required to change fluid types.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Johnsen's","offers":[{"title":"Default Title","offer_id":55170269380951,"sku":"B00C8720S8","price":106.23,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1050\/1524\/7191\/files\/johnsens-silicone-dot5-front-packaging.jpg?v=1790426376","url":"https:\/\/britishgarage.co.uk\/products\/johnsens-silicone-dot-5-brake-fluid-6-12-oz-non-hygroscopic-500-f-thermal-protection","provider":"British Garage","version":"1.0","type":"link"}
