syn brake fluid question

[evilmedic13]

After my trip to the doc today me and wifey stopped at an auto parts store because I still had to put my rear SS brake line on and needed to purchase some new fluid because I left the other bottle out w/o a cap and it got rained on! :angry: Stupid me, anyway, all they had was Valvoline Synthetic DOT 3&4 brake fluid that stated it was compatible w/ regular brake fluids and exceeded dot 3&4 specs, and it is NOT DOT 5 fluid, I know waaaay better than that,usually.

The question I have is if it's as safe to use as it says. I know, if I have to ask there's my answer but it seems to be all I could find recently, (must be a run on DOT 4 for some reason).

This is the best I can do for photo, can't link to website for some reason :angry:

Hopefully some one can help me on this. Also, it's going in the rear brake reservoir and system as the front brakes and clutch have been bled and refilled w/ DOT 4 fluid.

Thanks for any help,

Ed

Yes, you shall be fine. I have been using it for the last few years on my bike, my buddies bike, his track bike, and few other bikes.

I use the same stuff, no problems in 2 FJR's. I've had both stainless and regular brake lines, and both ABS and non-ABS. I used their synthetic grease as well.

Been using the Mobil 1 synth brake fluid for several years instead of the other stuff. You'll be fine, and may better. For me, the stuff seemed to last longer. I can't say for sure, but I've been wondering if the synth stuff is less hydroscopic (or whatever that word is that means "absorbs water").

Roadmammer here, Been using valvoline synpower ( full synthetic) for several years on my r100 BMW. It has performed great. We live in La Florida where the humidity is high and regular break fluid will last only a year or so before it starts to absorb moisture and turn dark. The full synthetic is not hdroscopic and stays clear for much longer. still I replace it every couple of years imho.
