To help with identification, glycol based fluids are clear or amber colored。brakefluid Glycol fluids are hygroscopic。 In terms, this means that they easily absorb moisture。 In addition, glycol based fluids will cause automotive paints to blister and peel and will soften or dissolve some hard plastics like styrene and ABS。 Care must be taken to prevent spilling glycol brake fluid on suces of the car。 DOT 5 silicone based brake fluid is available。 It has a higher boiling temperature and is not hygroscopic。

Most military vehicles and motorcycles are equipped with DOT 5 brake fluid。 Glycol and silicone based brake fluids are not chemically compatible。 Putting silicone based brake fluid in a system that has had glycol based fluid in it will result in softening and failure of rubber components。 DOT 5 brake fluid has a purple color so that it is not confused with glycol based fluids。 DOT 5 brake fluid cannot be used in a system that uses an electric pump motor。 most ABS systems because the spinning pump will cause the fluid to aerate or foam。

Some European cars BMW, Jaguar, Saab, Volvo, etc。 are equipped with a mineral oil based brake fluid。 This green colored fluid must NEVER be used in systems that are designed to use glycol based fluids。 The rubber components of glycol systems aren't compatible with the mineral oil based fluids and will be damaged。 Brake fluids are very susceptible to moisture contamination。 As little at 3% moisture in DOT 3 brake fluid will cut it’s boiling point in half。 Brake fluid containers must be kept tightly sealed。
