Each foil-wrapped strip is designed for single use: dip the brake end into the master cylinder reservoir and the coolant end into the radiator\/expansion tank (only when cool and diluted as installed). The color changes are easy to compare to provided reference charts, helping you decide whether maintenance is needed.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these strips reveal brake fluid condition?\u003c\/h3\u003e\n\u003cp\u003eThe brake end contains a corrosion-reactive pad that shifts from white toward purple as iron and other corrosive byproducts rise.

These test strips are ideal for DIY vehicle owners, independent mechanics, fleet managers, and anyone who wants objective proof of fluid condition before paying for service. They give a fast, low-cost way to spot corrosive brake fluid or low glycol\/acidic coolant that can cause component wear, letting you make informed maintenance decisions and avoid unnecessary service charges. Use them as routine checkpoints or when suspecting system issues—paired with manufacturer guidance, they help you prioritize professional service when needed.\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: How long does it take to get results?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Expect visible color change in 60–90 seconds for both brake and coolant pads.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can I test coolant concentrate with these strips?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No—test coolant only as it exists in the system at normal dilution (typically 50\/50).\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Phoenix Systems","offers":[{"title":"Default Title","offer_id":67595520901305,"sku":"B0753MZT7P","price":52.95,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0822\/3765\/3177\/files\/phoenix-systems-front-packaging_3f5358a2-21c6-4cfd-9e98-f3eb0df5f5af.jpg?v=1790588861","url":"https:\/\/redleafauto.ca\/products\/phoenix-systems-15-pack-double-ended-brake-fluid-coolant-test-strips-dual-end-60-90s-corrosion-glycol-ph","provider":"Redleaf Auto","version":"1.0","type":"link"}
