It has a typical dry boiling point of 269°C and a typical wet boiling point of 187°C, both comfortably above DOT 4 minimums. That gives a useful safety margin against brake fade during heavy braking, such as a long descent, a loaded van, or towing.\u003c\/p\u003e\n\u003cp\u003eThe fluid's very low viscosity is what sets it apart. At just 810 cSt at -40°C (900 cSt maximum), it flows quickly through the small valves and passages of ABS, ESP and traction control units, so these modern safety systems respond quickly even on a cold winter morning. That makes it a good match for current cars with complex electronic braking systems.\u003c\/p\u003e\n\u003cp\u003eFBZ050A is glycol-ether based and meets FMVSS 116 DOT 5.1 and ISO 4925 Class 5.1. It's also suitable for hydraulic clutch systems. It's low-corrosion and causes very little rubber swell, protecting seals, hoses and metal components throughout the brake system. The \"A\" suffix indicates the Western European version, with health and safety labelling in English, French, Dutch, German, Spanish, Italian, Portuguese, Danish, Swedish and Arabic.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDOT 5.1 specification\u003c\/strong\u003e: meets FMVSS 116 DOT 5.1 and ISO 4925 Class 5.1.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e269°C typical dry boiling point\u003c\/strong\u003e (260°C minimum spec).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e187°C typical wet boiling point\u003c\/strong\u003e (180°C minimum spec), so it keeps performing as it ages in service.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVery low viscosity\u003c\/strong\u003e (810 cSt typical at -40°C), ideal for ABS and ESP braking systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrake and clutch fluid\u003c\/strong\u003e for cars, vans and motorcycles designed for synthetic glycol-based fluid.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow corrosion\u003c\/strong\u003e, protecting calipers, cylinders and brake lines.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVery low rubber swell\u003c\/strong\u003e, which is kind to seals and flexible hoses.\u003c\/li\u003e\n\u003cli\u003eSupplied in a sealed \u003cstrong\u003e500ml bottle\u003c\/strong\u003e.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Ferodo\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e FBZ050A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification:\u003c\/strong\u003e DOT 5.1 (FMVSS 116 \/ ISO 4925 Class 5.1)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBase:\u003c\/strong\u003e Glycol ether (polyalkylene glycol ether and esters)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDry Boiling Point:\u003c\/strong\u003e 269°C typical \/ 260°C minimum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWet Boiling Point:\u003c\/strong\u003e 187°C typical \/ 180°C minimum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKinematic Viscosity at -40°C:\u003c\/strong\u003e 810 cSt typical \/ 900 cSt maximum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVolume:\u003c\/strong\u003e 500ml\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended Use:\u003c\/strong\u003e Road\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEAN:\u003c\/strong\u003e 4060426489700\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat Is Ferodo DOT 5.1 Suited To?\u003c\/h3\u003e\n\u003cp\u003eFBZ050A is ideal for routine brake fluid changes on road cars, SUVs, light commercial vehicles and motorcycles, particularly modern vehicles with ABS, ESP and traction control. It's also a straightforward upgrade for cars that currently run DOT 3 or DOT 4 fluid, as it has higher boiling points and better cold flow. For regular track days or motorsport, choose one of Ferodo Racing's dedicated race fluids, such as Super Formula (FSF050) or FRF340.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is the difference between DOT 4 and DOT 5.1?\u003c\/h3\u003e\n\u003cp\u003eBoth are glycol-based, but DOT 5.1 has to meet tougher requirements. Its minimum dry boiling point is 260°C (DOT 4 is 230°C), its minimum wet boiling point is 180°C (DOT 4 is 155°C), and its maximum viscosity at -40°C is 900 cSt (DOT 4 is 1800 cSt). The result is more resistance to fade and faster flow through ABS and ESP units.\u003c\/p\u003e\n\n\u003ch3\u003eIs DOT 5.1 the same as DOT 5?\u003c\/h3\u003e\n\u003cp\u003eNo, and this is important. DOT 5 is silicone-based and is not compatible with glycol-based fluids. DOT 5.1 is glycol-based, like DOT 3 and DOT 4. \u003cstrong\u003eNever mix FBZ050A with DOT 5 silicone fluid\u003c\/strong\u003e, and never put it in a system designed for DOT 5.\u003c\/p\u003e\n\n\u003ch3\u003eCan I use DOT 5.1 in a car that specifies DOT 4?\u003c\/h3\u003e\n\u003cp\u003eIn almost all cases, yes. DOT 5.1 is compatible with DOT 3 and DOT 4 systems and exceeds their performance requirements, so it's a common upgrade. Always check your vehicle handbook first, as a small number of manufacturers specify a particular fluid.\u003c\/p\u003e\n\n\u003ch3\u003eCan I mix it with the fluid already in my car?\u003c\/h3\u003e\n\u003cp\u003eFBZ050A is chemically compatible with other glycol-based DOT 3, DOT 4 and DOT 5.1 fluids, so topping up won't cause a problem. However, for the best boiling point and ABS performance, we recommend a complete flush so the system contains only fresh DOT 5.1 fluid.\u003c\/p\u003e\n\n\u003ch3\u003eIs it suitable for motorcycles?\u003c\/h3\u003e\n\u003cp\u003eYes. It's suitable for motorcycles designed to use synthetic glycol-based brake fluid (DOT 3, DOT 4 or DOT 5.1). It isn't suitable for bikes that specify DOT 5 silicone or mineral oil.\u003c\/p\u003e\n\n\u003ch3\u003eCan it be used in the clutch system?\u003c\/h3\u003e\n\u003cp\u003eYes. FBZ050A is a brake and clutch fluid, and it's suitable for hydraulic clutches that share, or are separate from, the brake fluid reservoir.\u003c\/p\u003e\n\n\u003ch3\u003eHow often should brake fluid be changed?\u003c\/h3\u003e\n\u003cp\u003eGlycol-based brake fluid absorbs moisture over time, which lowers its boiling point and can cause internal corrosion. Most vehicle manufacturers recommend a change every two years. Follow the interval in your service schedule, or change it sooner if a moisture test shows high water content.\u003c\/p\u003e\n\n\u003ch3\u003eHow much fluid do I need?\u003c\/h3\u003e\n\u003cp\u003eA full flush on most cars uses around 1 litre, so two 500ml bottles is usually enough. A simple top-up or a motorcycle may only need one bottle, while larger vehicles or systems with a shared clutch reservoir may need more.\u003c\/p\u003e\n\n\u003ch3\u003eIs it suitable for track days?\u003c\/h3\u003e\n\u003cp\u003eFBZ050A is designed for road use. For occasional spirited driving it performs well, but regular track days and motorsport produce much higher brake temperatures. For those, a dedicated high-boiling-point race fluid such as Ferodo Racing Super Formula or FRF340 is the better choice.\u003c\/p\u003e\n\n\u003ch3\u003eHow should I store an opened bottle?\u003c\/h3\u003e\n\u003cp\u003eKeep the cap tightly closed, and store the bottle upright in a cool, dry place out of the reach of children. Once opened it starts absorbing moisture from the air, so use it promptly. Don't reuse fluid that has been bled out of a system.\u003c\/p\u003e\n\n\u003ch3\u003eWill brake fluid damage paintwork?\u003c\/h3\u003e\n\u003cp\u003eYes. Like all glycol-based brake fluids, it will damage paint and some plastics. Cover painted surfaces when working, wipe up spills immediately and rinse with plenty of water. Brake systems should only be serviced by competent mechanics.\u003c\/p\u003e\n","brand":"Ferodo","offers":[{"title":"Default Title","offer_id":66015309267334,"sku":"FBZ050A","price":9.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1070\/8169\/5581\/files\/ferodo-dot-5-1-brake-clutch-fluid-500ml-fbz050a-1.jpg?v=1790328520","url":"https:\/\/www.thebrakeshop.co.uk\/products\/ferodo-dot-5-1-brake-clutch-fluid-500ml-fbz050a","provider":"The Brake Shop","version":"1.0","type":"link"}
