Bosch Automotive Esi6 32N Brake Fluid Direct Replacement For Dot 3, Dot 4, And Dot 5.1

I’ve used a lot of different brake fluids over the years, and this Bosch ESI6 has become my go-to. I originally bought it because of its extended service life and compatibility with DOT 3, DOT 4, and DOT 5.1 systems. What I didn’t fully appreciate at the time was just how much of a difference the low-viscosity formula makes in cold weather. After flushing my system and using this fluid through a winter in the Pacific Northwest, I noticed that my ABS felt noticeably more responsive during snow trips to whistler and Stevens. The brake pedal felt more consistent, and ABS activation was quicker and smoother when traction was limited. Looking back, that cold-weather performance was something I completely overlooked when I first purchased it, but it’s become one of my favorite features. The fluid was easy to work with, the packaging seals well, and I have confidence in the Bosch name. If you live anywhere that sees freezing temperatures or simply want a high-quality brake fluid with excellent all-around performance, I highly recommend this product. It’s one of those upgrades you don’t really notice every day—until the conditions get bad, and then you’re glad you chose it. I do use this fluid in two vehicles that are driven aggressively and can attest that it does hold up very well to high temperature use….

Perfect fit for my 2016 F150. Easy no spill pour from the can as well. Does the job and the price is a fraction of what Ford sells the same stuff for. Highly recommend.

I checked the specs on most of the DOT3 / DOT4 brake fluids commercially available, some priced lower and many priced higher before buying. Aside from "full race" rated fluids, this had one of the highest boiling points available and met all of the requirements of my '22 Indian. It was highly rated and well reviewed. Motorcycles have small brake fluid reservoirs and the manufacturers recommend changing the fluid every two years due to hydroscopic water infiltration. I was getting a spongy rear brake pedal, the pads had plenty of life left, so I replaced the old fluid with this. I don't ride aggressively, and baggers aren't normally part of "Track Days", so this fluid exceeds all of my bike's demands. It was easy to replace and bleed with a vacuum kit. For the price, this Quart was an excellent value. There's enough to do all three lines on the bike, with plenty left over to start another job (but not enough to do all of the lines and the reservoir in my Crew Cab Truck). The pedal / lever is firm again. I'm a happy rider. Five Stars!

I use it not just the first time. It works fine and the quality is good, I guess, since I never had a problem with this fluid. Also, the container is very secured and isolated from the air moisture. So you can use the stored fluid for a long time without it getting moisture from the air.

Good fluid, for the balance between LV and high wet boiling point (other DOT4 fluids are higher wet boiling, but viscosity of DOT4, this is similar viscosity at -40c as the LV fluids (SL.6, etc.), but has a higher wet boiling point. About the same cost as the rest of... (Amazon cut off the rest for using the word 'h**l') The shipping of this item just sucks!
