If the synthetic fluid is silicone based, yes. If it is a dot 3or 4 type, no.

yes,,,, all brake fluid is synthetic. EXCEPT Dot 5 which you CANNOT mix only because it is silicone based.
Dot 5
BRAKE FLUID DOT 3 IS WHAT IT CALLS FOR You can use dot 4 also but never dot 5, it is silicone based and will not mix, it is for racing only.
I would say any fluid could act as a coolant. Brake fluid DOT 3, 4 and 5.1 is a polyethylene glycol based fluid. DOT 5 is a silicone based fluid. DOT 3, 4 and 5.1 will absorb water, reduce its boiling point and degrade its performance.
DOT 3, DOT 4 or DOT 5.1 (but NOT DOT 5, which is silicone brake fluid) can be used in your car.
Because oils damage rubber seals and hoses in the braking system, brake fluids are not petroleum-based. Most brake fluids used today are glycol-ether based, but mineral oil (Citroën liquide hydraulique minéral (LHM) and silicone (DOT 5) based fluids are also available.
Only brake fluid can be used for brake fluid. Brake fluid is a glycol-based liquid - it's closer to antifreeze than to oil, but don't use antifreeze in it either. Only brake fluid.
DOT 5 is a silicone brake fluid and not compatible with the original fluid or components. IF the system is contaminated, take it SOON to a reputable shop for help.
If it calls for dot 5, yes. If it has dot 3 or dot 4, no.
silicone brake fluid, I think it is dot 6 or something like that, you have to remove all of the old fluid first, can't mix at all.. but that will have less brake fade and higher bubbling temps. they use it in race cars.
