Good stuff. Used this after the Master Cylinder Rebuild on my 02 Road King. Ended up with nice firm brakes. Love the Purple coloring, made bleeding the brakes a breeze being able to clearly see the color change when getting to the fresh fluid.

I flush the DOT 5 brake fluid in my Harley every year using speed bleeders and I use DOT 5 from Belray and from Harley alternating the Belray and Harley brake fluid each year. Why? The Harley fluid is clear and the Belray is a blue/purple color and I can tell the clear from the blue when I’m flushing the brakes. Nice!Make sure your application requires DOT 5 – it’s silicone based and does not absorb water and it also won’t eat paint if it gets spilled but it MUST be the fluid required because you can destroy your brake seals and hoses with the wrong fluid.
