    A Special Note about Email accounts!
    DO NOT SIGN UP USING hotmail, outlook, gmx, sbcglobal, att, bellsouth or email.com. They delete our forum signup emails.

    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

thanks for the info. I was most interested in the dot 5 for it's anti-corrosiveness. It sounds like it would work O.K. as long as you're using new parts, and stay out of the water.
 
Dot 5.0 gives a "spongey" feeling compared to Dot 4 or 5.1. Some people don't like (it's noticeable at the pedal in a car, not tried it on a bike).

It's fine for use in a new system in any vehicle, the danger with using in a used system is that it reacts with the DOT4 on the seals & makes them swell which can lead to things locking up.

As long as you replace with new seals & hoses all the way through you should be ok.
 
I believe dot 5 has a higher boiling point and is less prone to absorb water, but need to be changed more often.
 
You are talking about Dot 5.1.

Dot 5.0 is silicon and does not absorb water. That is it's key benefit (Although some have reported that it's possible to get water "pockets" in the lines trapped by the silicon).

I believe (but am not 100%) that it was developed for Army / Emergency vehicles that would not be used for a long time but needed to be ready at a moments notice. The fact that it's not flammable & doesn't strip paint are good benefits to some too...
