1. Composition and Viscosity: Brake fluid is specifically formulated for brake systems and has a lower viscosity than power steering fluid. This difference in viscosity can affect the performance and efficiency of the power steering system, leading to reduced responsiveness, increased effort while turning the steering wheel, and potential damage to the power steering components.
2. Compatibility and Corrosion: Brake fluid is generally not compatible with the materials used in power steering systems, such as seals and hoses. Brake fluid can cause these components to deteriorate and swell, leading to leaks and potential system failure. It can also corrode metal parts within the power steering system.
3. High Temperature Performance: Power steering systems can generate significant heat during operation, and brake fluid has a lower boiling point compared to power steering fluid. This means that brake fluid can boil more easily, leading to vapor lock in the system and reduced power steering performance, which could be dangerous while driving.
4. Lack of Additives: Power steering fluid contains specific additives designed to protect the seals, hoses, and metal parts of the steering system. These additives help prevent corrosion, wear, and oxidation. Brake fluid does not contain these additives, so using it in the power steering system can lead to premature wear and failure of these components.
5. Compromised Safety: Substituting brake fluid for power steering fluid jeopardizes the safety of the vehicle. A malfunctioning power steering system can affect your ability to control the vehicle, increasing the risk of accidents. Relying on ineffective or poorly performing power steering can lead to impaired vehicle handling, especially during maneuvers that require precise steering control.
If you suspect that brake fluid has been mistakenly added to the power steering system, it's important to have the system flushed and refilled with the correct power steering fluid as soon as possible. Using the correct fluids as specified by the vehicle manufacturer is crucial for optimal performance and longevity of the power steering system.
