Stick to a good glycol fluid like Motul RBF600 or ELF ETX115.
Don't bother with silicone fluids, they are a waste of time and money.
-While they do not absorb water they do not stop water from entering the brake system and can allow water to gather at the lowest points in the lines, promoting corrosion.
-Silicone fluids are more compressible than glycol, leading to a spongyfeeling brake pedal.
-You can't mix silicone fluids with glycol fluids.
-Not compatible with most ABS systems.
