Subject: Brakes- Fluid- Dot 3,4,5???

Date: 28 Feb 1997 10:51:00 -0800



A recent contributor recommended flushing the system every 3 years or =

so. In that light, where do recommendations stand in regards to the =

different DOT versions?



I know that DOT 5 is a silicon based fluid that is resistant to water =

retention, which is a problem with DOT3 fluid. This is why your fluid =

comes out looking like dirt after only a short while in the system.

DOT 5 is typically reserved for motorcycles and is not recommended for =

autos due to heat problems of some sort. It would seem to be the magic =

cure for rust prevention in cars driven little, if it weren't for this =

problem with heat. (as I understand it.)



In one of my recent projects, I started using a Castrol DOT 4 fluid =

which is supposed to "exceed DOT 3 ....blah blah"  It claims to resist =

water absorbtion better than DOT 3 and perform better....  I am hoping =

that this will be a cleaner solution.



Any scientists out there that can shed some light on this situation?
