Was being lazy and rather than to drive for just a can of fluid, I took advantage of my prime shipping and ordered this Dot4 bottle. Works good and noticed better stopping power on my motorcycles.

Use this stuff in my motorcycles that call for DOT 4 brake/clutch fluid. The reason that I bought it here was because I could not find straight DOT 4 brake fluid at any auto parts stores or the big retail (chain) stores. They only carried DOT 3/4. Pricing this out by the fluid ounce it was pretty comparable with the 3/4. I like that it is made for heavy equipment and has a high flash point. Overall, no problems. I went through one quart in my motorcycles and bought another quart.

I just completed bleeding my front and rear brakes and also the clutch line on my Suzuki Bandit. The old fluid must have been the original stuff. It was a dark brown color. Now I'm riding much safer with a fresh brake and clutch line fluid change. Tested and works for both lines as expected.

GOOD ENOUGH. NO WAY TO TELL IF THIS IS BETTER OR WORSE THAN OTHER BRANDS, BUT IT WORKS JUST FINE. I ASSUME DOT4 IS BETTER THAN DOT 3 AND WORTH THE COST.

I do plenty of brake jobs on all kinds of vehicles. Needed to buy DOT4 for my 2010 Harley-Davidson Fat Boy......This did the trick!

What can I say about brake fluid, it's dot 4 "super heavy duty" brake fluid. Competitively priced, on time shipping.

There's not much to say about this product other than it works. I used it to bleed my Honda Shadow and SV650s brakes.

Good replacement for more expensive heavy dot 4 fluids that could cost up to $20. I'm happy with my purchase.
