Trusted by Tesla, these scientifically validated strips detect corrosion and fluid degradation in just 60-90 seconds, empowering you to avoid unnecessary maintenance costs and keep your vehicle running safely and efficiently. ## Description Most of the time, knowing when to change your brake fluid or coolant is a guessing game. With Brake Strip and Coolant Strip, in as little as sixty seconds you have clear, repeatable and reliable proof of the level of corrosion in your vehicles brake fluid and the acid plus freeze/boil point of your coolant. The test starts with removing your brake master cylinder cap and dipping the Brake Strip end of the test strip into the fluid, next you will remove your radiator cap and dip the coolant end of the test strip into the antifreeze. CAUTION: DO NOT remove the radiator cap when HOT! Once dipped in brake fluid, Brake Strip begins the corrosion measurement reaction - changing color from white to purple in direct proportion to the corrosion level. High levels of corrosion indicate brake fluid that has lost its ability to protect your brake system. Corrosive brake fluid should be changed and a dose of "Brake Shot" should be added to protect against future corrosion Simply search for "Brake Shot" Once dipped in coolant, Coolant Strip begins the pH and glycol measurement reaction. The glycol pad can range from pink to red/blue depending on your glycol percentage. The pH pad can range from orange to yellow/green depending on the acid or alkaline level. Low levels of glycol can quickly lead to a corroded water pump, heater core and radiator. Low glycol can also cause an engine to freeze in cold weather and create a crack through the engine block. pH levels below 7 indicate acidic coolant. Acidic coolant will also quickly corrode a cooling system and lead to premature breakdowns and an unreliable vehicle. Coolant Brake Test Strips give you confidence to know the right time to change your fluids. Don't let a shop pull the wool over your eyes! Find out for yourself if your fluids needs to be changed or not. Be sure to use these to test the coolant (generally diluted 50/50) as it is in the vehicle. DO NOT test coolant in full concentrate without proper dilution. Review: Good price, quality and ease of use - Really like these strips! They did a good job in showing the efficacy of the coolant and brake fluid in both my vehicles. Excellent way to test the newer, long-life coolants - from what I've read, the two tests are what is needed for those coolants. Found out things were in good shape, but the brake fluid was getting a little "long in the tooth" on one (which I wouldn't have guessed). Easy to read the results with the color key on the package. And each strip comes in it's own sealed foil packet, which should help with shelf life. Review: Avoid paying for service you don't need! - I'm retired and only drive about 3000 miles per year. So, the manufacturer's recommended maintenance intervals are not useful for me. This test kit allows me to test both the brake fluid and coolant to see when they actually need to be replaced. FYI, the factory installed coolant and brake fluid both checked out OK at 26,000 miles in my 2018 Sentra. So, I saved $250 on service I didn't need to do. The instructions are clear and the tests are VERY EASY to do. ## Features - 15 Double-Ended brake fluid tester and coolant - Gives you the peace of mind that your Brake fluid is good and is safely performing its proper function - Identifies potential Brake fluid and coolant related problems before they occur -thereby ensuring your safety and fewer breakdowns - Simply remove the test strip from the foil wrapper, Dip it into your Brake fluid then coolant/antifreeze, and 60 to 90 seconds later you will know the condition of your fluids.
