if the dot 5 fluid is in a black bottle. remove the cap and foil seal, lightly re install the cap to let the air out. let it sit out in the sun for a few hours to force out the air bubbles that develop during shipping.
if in a light colored bottle. put it in a pan of hot water, about 200*, for about 15 min.

What is the big advantage of 05 over 03
First and foremost, paint friendly...
Does not absorb moisture...
Higher boiling point...
Research its development...
I've had Dot 5 in a '71 B-body for over 20 years...
I would never go back to DOT 3...

I wouldn't mix it either. But if you drain , fill and bleed, I've never had an issue. You can tell by the color when all the old fluid has been bled out. Any minuscule fluid remaining has never caused a problem for me. Doug

I agree, a thorough cleaning is not necessary. If it's of any concern to you. Bleed the system every couple years, at least a few pumps out the bottom.

Not to hijack but I am redoing the braking system on a 72 RR...Power Disc/Drum. I am replacing the brake lines front to rear. Going to rebuild the calipers and the wheel cylinders. The car is currently DOT3. Would you say to go to DOT4 or DOT5? What do I have to do to the Master besides Bench bleeding it? Do I need to clean it out with something?>

what kunkel said is correct. federal LAW says DOT 5 brake fluid MUST be to coexist with other brake fluids without causing harm. if it wasn't it wouldn't be able to be sold in the US.
i don't have time to look this up and post it. it has been posted several times in the past. do a goggle search on moparts to find lots of info on this subject.

This subject comes up all time on boards all over the place. Mr. Kunkle is correct. I am amazed that someone would think you could sell a simple product, that if used wrong, could cause a failure and kill...thousands... world wide. Wikipedia says mixing will cause failure....I don't believe it, the legal implications of that are mind boggling.
As I understand it, it was developed by either (or both) the Military or Post office as they felt the DOT 3 stuff wasn't the best for their equipment, which sits around a lot not being used. Its good stuff, use it.
