Use direct boiling point analysis to accurately and consistently determine the affect moisture has on brake fluid. Brake fluid is the most abused fluid in your car. Brake fluid should be replaced periodically. Two types of contamination affect brake fluid. Created through physical wear, corrosion and breakdown of components within the hydraulic system.
Brake fluid is hygroscopic.
This means it absorbs moisture. Moisture is absorbed through rubber parts such as brake hoses, caliper seals, and wheel cylinder cups. Either type of contamination can cause serious problems and should be flushed from the system. As brake fluid absorbs moisture, the boiling point is reduced and corrosion can occur. Due to the high temperature created in a brake system, the reduced boiling point can cause the brake fluid to boil.
