Re: [FWDLK] Brake fluid

[Mike Apfelbeck <moparmike72@xxxxxxxxxxx>]

Dot 3 is pretty much obsolete these days, dot 4 is lots better. Dot 5 
is silicone based and isn't compatible with 3 & 4, it will turn into 
gel if you don't remove all traces of the other fluid in the system 
first. It isn't hygroscopic, doesn't absorb water, any water in the 
system will settle out in the lowermost part of the wheel cylinders, 
it should be drained and flushed annually to keep corrosion at bay. 
It aerates more easily than the other kind, more care is needed to 
get the air bled out of the system. On the other hand, it won't eat 
up paint like regular brake fluid if it gets spilled on it. Dot 5.1 
is regular type fluid, not silicone based, it's thinner viscosity for 
use in newer anti-lock brake systems.
