Maxima Racing USA 80-81916 DOT 5 Silicone Brake Fluid, Single

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!

Good brake fluid for heavy duty use great for classic cars won't absorb moisture.

I have always used this SILICONE brake fluid in my Austin America. I use it because the brake and clutch master cylinders both sit on the firewall and spilled fluid damages and streaks the paint. This silicone fluid works great and no paint damage.

My Harley custom that I Built Stops on a Dime !!!

Boiling point claimed is not the same as labeled on the bottle. I am very disappointed to make this discovery.
