Dot3 vs Dot 4 brake fluid.

[bikerchris1270]

Your Spyder probably uses DOT 4 brake fluid with a maintenance schedule of every 2 years……Dot 4 has a tendency to absorb more moisture from the atmosphere than Dot 3 fluid, BUT….. Dot 4 has a higher boiling point with less seal swell than Dot 3.
My Spyder only has 11k on it and I found the fluid very dark instead of the amber color of new fluid……… just saying…….. probably good not to overlook the required maintenance.

If you haven’t performed this maintenance yet, would recommend getting speed bleeders. Makes the job super easy. Buy the bag and hose from them also. Took me 45 minutes and didn’t spill a drop of fluid.

+ 1 on the speed bleeders.

That, along with a vacuum pump on a catch jar, makes it a 10 minutes job.

Took longer to put the old brake fluid back in the container to be disposed of than it took to change the fluid.

X3 They are a great tool in your box of tricks, if you choose to install them!!!!

My 4 wheelers require DOT 3 and the spyder DOT 4 so I use this.

Our shop has an abundance of DOT 5.1 (NOT 5) so that's what I use...

Mike, click back on their home page and you will find their charts for different type vehicles. Love mine. They will become a standard addon for anything in the future.

Your 4-wheelers might "require" DOT3, but DOT4 will work in them just as well (or better).

It is good that you know the difference that ".1" makes. DOT5 fluid is silicone-based and is not compatible with DOT3 or DOT4. I think there might be issues with seals, too, you need to ensure that the entire system will work with DOT5. For some reason, they came out with a DOT5.1 that is compatible with DOT3 and DOT4, but has improvements. The (unfortunately) similar name can be rather confusing.
