Description
Prestone DOT 3 Motor Vehicle Brake Fluid delivers enhanced performance vs. DOT standards, benefitting all vehicles calling for DOT 3. This synthetic fluid starts with a higher dry boiling point than the DOT minimum standard to protect against overheating, brake fade and performance decline due to water absorption. This extended life (50,000 mile) fluid is also formulated to prevent corrosion of all metals within the braking system. This formula is safe to use in all DOT 3 braking systems (ABS, disc or drum) and can mix with any DOT 3 fluid. It is recommended to only use the DOT fluid specified for your car, as using a different DOT product can affect the boiling point or replacement interval if the wrong fluid is used.

Reliable Brake Fluid for Everyday Use
Size: 12 Ounce
The Prestone AS400 DOT 3 Synthetic Brake Fluid has been a dependable choice for my vehicle maintenance. As someone who likes to handle DIY projects without spending a fortune, this brake fluid has proven to be both effective and affordable. It performs well, maintaining the braking system's efficiency and responsiveness. One aspect I appreciate is the consistent quality. Even after several uses, it remains reliable, ensuring my vehicle's brakes operate smoothly. The bottle's design makes it easy to pour without any mess, which is a nice touch for someone who does their own car maintenance. One thing to keep in mind is that you need to ensure it's compatible with your vehicle's specifications, but that's standard with any brake fluid. For anyone looking for a cost-effective and reliable brake fluid, Prestone AS400 is an excellent choice. It's been working well for my needs, and I have no complaints about its performance or value. Perfect for any DIYer looking to maintain their vehicle on a budget.

Works perfectly
Size: 12 Ounce
What can I say about this standard product. If you need it for your brakes then it's a no brainer. Just get the right kind designed for your particular car model. This is actually cheaper than the local O-Reilly's which always have a long line, and shipped to the door.

I NEEDED IT TO CHANGE MY BRAKE FLUID
Size: 12 Ounce
A mechanic told me I need to change my brake fluid in the brake reservoir because it was dirty. He wanted one hundred dollars to do the job. Yikes! I assumed he was lying since most mechanics try to get you to do more repairs on your vehicle. My vehicle is 15 years old and has never had the brake fluid changed before. I did some research on when and why you change brake fluid and I checked on youtube on how to change the fluid. Seemed pretty easy (and I'm a girl) so my friend and I did it ourselves (2 person job). I purchased 9 bottles of this 12 ounce bottle of brake fluid here on Amazon. I wanted to do my other vehicle (Bronco II) too, which is almost 30 years old and has never had the brake fluid changed either. My bad! I ended up purchasing 6 more bottles of this 12 ounce brake fluid 7 days later. Why? Because they were only 2 dollars for each bottle here on Amazon. Each vehicle used up between 3 and 4 bottles and we're going to do 2 more vehicles. That's a savings of four hundred dollars. There was a definite change in the feel of the brake pedal after changing the fluid. Especially in the 30 year old Bronco II. Glad I changed the fluid. The fluid color went from a darkish green color to clear. WOOT, WOOT!!
