It lasts maybe 4 months, but it works really well for those 4 months…Įither way, dot3 is dot3. If you race, motul RBF 600 seems popular. It doesn’t last quite as long as the honda stuff, but I find it gives more positive feel. I’ve heard several reports of premature water pump seal failures due to silicate contamination with other coolants.ĪTE SuperBlue or gold (Same stuff, one’s blue and ones gold to easily see when you’ve totally flushed the fluid) is what I use, and it meets DOT4. Honda makes a great non-silicate coolant, and I wouldn’t use anything else. However, Honda’s PS fluid is special - only use the OEM stuff as it is thinner than other stuff - using thicker aftermarket PS will possibly damage the seals. Aftermarket fluids are fine as long as they meet DOT 3 or 4.
That is why you need to change the brake fluid right away to avoid any potential problems that may occur.Amongst the racing / “ricer” communities, it is popular to use other / aftermarket brake fluid. Not only that, you’ll want the mechanic to run a diagnostic check on your braking system to see if any of the components were damaged from the wrong braking fluid being used.Įven though your brakes may have felt like they worked on the way there, it doesn’t mean they will keep on working over the next several days or weeks. If you realized that you put the wrong brake fluid in your vehicle, the first thing you should do is take the vehicle to the nearest auto repair shop or shop that specializes in brakes and have them drain it for you.

But before you do so, check the condition of the fluid to make sure you don’t need to change it out. If the brake fluid level is around the “MIN” line, then it means you need to top off your brake fluid. Your brake fluid reservoir will have marks which are usually labeled “MAX” and “MIN or “FULL” and “ADD.” Sometimes the brake fluid level drops when you have worn brake pads. It’s a bit trickier than an oil change and there’s no embarrassment having the pros perform the service if you’re not confident enough in your abilities to do it yourself. You’ll want to perform a brake fluid flush according to the manufacturer’s stated interval.Ī brake fluid flush is essentially the process of replacing old brake fluid with fresh new fluid. Like engine oil, brake fluid will attract impurities and eventually break down. Changing Brake FluidĪ lot of people don’t think that they ever need to change their brake fluid and this is completely wrong. Unfortunately, its wet boiling capacity is not so great. This means the fluid will work well when it’s exposed to water and the open air.ĭOT 4 braking fluid is best when it comes to a dry boiling capacity. #4 – Boiling CapacityĭOT 3 braking fluid contains both a great wet boiling capacity and dry boiling capacity. Always follow the vehicle manufacturer’s recommendation as to what type of brake fluid to use. However, you can expect to see DOT 4 braking fluid in police cars, motorcycles, and racing cars since they all brake more frequently and aggressively.
#DOT 3 BRAKE FLUID AUTOZONE DRIVER#
The average economy car will use DOT 3 braking fluid because in general, the cars require less stopping power and the driver won’t be braking aggressively very often. This mixture makes the brake fluid more stable and able to handle higher temperatures. This mixture creates a brake fluid that can handle wet conditions and average heated conditions.ĭOT 4 brake fluid is made of borate and glycol. #2 – Chemical ComponentsĭOT 3 brake fluid is made from ether and polyalkyelen glycol being mixed together. Car owners who are involved in autocross or lapping days at the track will definitely require a brake fluid with a high boiling point. If you tend to do a lot of heavy braking with your vehicle, then DOT 3 brake fluid could easily boil which would result in the complications noted above.ĭot 4 brake fluid is more reliable when you’re regularly doing a lot of heavy braking because it doesn’t boil as easily.
