High performance silicone-based brake and clutch fluid designed to lubricate and protect critical brake system componentry while providing reliable stopping power. Anti-vapor lock formulation maintains responsiveness and performance by fighting vaporization and viscosity loss. Advanced chemistry resists corrosion, oxidation and is compatible with SBR, EPDM and natural rubbers. Ideal for use in vehicles where incidental contact of brake fluid can damage finishes. Exceeds the requirements of US FMVSS 116 DOT 5 specification, mixes with other DOT 5 Brake Fluids. High boiling points: Dry Boiling Point 572°F (300°C), Wet Boiling Point 429°F (220°C).

I have a 77 CB550 and a 79 CM400, both use DOT3 and both have had to be rebuilt over the past decade because the glycol just eats through stuff if you don't flush it out every year.This time around I had a mechanic convince me to switch to silicone DOT5. This bottle is pricey, but it is enough to easily do 4 or 5 single piston front ends. You'll need a vacuum bleeder in order to do the job.There's two ways you can do it. First one is to disassemble the caliper and master cylinder, remove the hoses, and then flush all of it out with acetone or denatured alcohol. Then dry it out with clean towels and let it sit overnight to dry where you can't reach. I'd recommend this for older systems.However, if your system has been rebuilt recently and is very clean inside you can simply vacuum out the glycol from the master cylinder and then use the vacuum pump to suck out the remaining glycol from the bleeder. Then put your silicone in and fill it up. Keep purging until it's clean. Despite what internet lore says, DOT5 has been made to mix with a small amount of glycol.Make sure you let the bottle sit upright for about an hour or so before you use it. Open it up and make sure there isn't a lot of tiny bubbles in there. If there is, you need to let it sit and settle otherwise bleeding will be difficult. Pour it slowly at the top and then use the vacuum bleeder and have at it.This stuff works great! Lever feel and brake feel is exactly the same as the glycol. If it feels spongy you got air in the system, fix it. I found that having to do about 3 reservoir top offs was the amount for me to get the correct lever feel and no bubbles in the system. After that, enjoy not having to deal with your vintage brake system getting corroded!
