If you have an all new brake system, you should use Dot 5 Silicone brake fluid. Does not absorb moisture and will not eat paint... :thumbsup:
I went all DOT 5 when I replaced the system
I used this reference. There's always debate :lol:
The advantage of the silicon based DOT5 fluid is that it absorbs no moisture whatsoever, unlike the glycol-based fluids. Because it is also chemically inert it won't react with other chemicals in your braking system, nor will it even react to your car's paint which the glycol-based fluids will. For that reason,DOT5 fluid is also preferred for
vintage and antique cars that don't get driven around a lot. It can be left to sit in the system arguably for the life of the car without causing any problems.
The different numbers in
brake fluid represents the different ways that these brake fluids handle temperatures. The rating refers to the fluid’s boiling points when they are either wet or dry. Brake fluid with a higher boiling point will typically last longer than one with a lower boiling point.
DOT2: DOT2 brake fluid has a dry boiling point of 190 degrees Celsius. The wet boiling point is 140 degrees Celsius. This is a mineral oil-based fluid and is rarely used in the automotive industry thanks to its relatively low boiling points.
DOT3: DOT3 brake fluid has a dry boiling point of 205 degrees Celsius. The wet boiling point is 140 degrees Celsius.
DOT4: DOT4 brake fluid has a dry boiling point of 230 degrees Celsius and a wet boiling point of 155 degrees Celsius.
DOT5: DOT5 brake fluid has a dry boiling point of 260 degrees Celsius and a wet boiling point of 180 degrees Celsius.
DOT5.1: DOT5.1 brake fluid has a dry boiling point of 270 degrees Celsius and a wet boiling point of 180 degrees Celsius.
