As I understand it =
the "DOT"
means Department of Transportation. The "3, 4, 5" is a set of =
specifications
that the break fluid has to meet in order to be approved by the DOT. As =
far as I
know the "4" or "5" is not necessairly better than the 3, just =
different. The 3
may be better than the 5 for some applications. As far as actual use is
concerned all I know is that the manual says the break fluid must meet =
or exceed
DOT 3 specs. As long as you have that you are OK. Some fluids claim to =
be better
than others but I dont know about that.
Castrol HAS however =
come out
with a synthetic fluid that seems to be good. Regular break fluid LOVES =
water
and will absorb all it can get. This is one of the BIG reasons why they =
say to
change the fluid every couple of years. The new Castrol claims to HATE =
water and
will absorb little or none. That alone will make it better whatever =
other
benefits it has. It also claims to be compatable with DOT 3 and can be =
mixed
freely with it. Unless I hear some discouraging words regarding it I am =
going to
give it a try this summer.
Could =
somebody please tell
me about Brake Fluid.
What the DOT 3-4-5-? pertains =
