Can You Use Brake Fluid for Power Steering?

This article addresses the critical question: Can you use brake fluid for power steering fluid? The straightforward answer is no, brake fluid and power steering fluid are not interchangeable. They are specifically formulated for two distinct systems in your vehicle – the brake system and the power steering system.

What is Power Steering Fluid?

Power steering fluid is essential for the smooth operation of your vehicle’s steering system. This petroleum-based fluid lubricates the hydraulic system components such as the pump and valves. It assists drivers by reducing the effort required to turn the steering wheel, allowing for precise and effortless vehicle maneuvering. Key requirements for power steering fluid include maintaining stability in viscosity, being incompressible, and ensuring no residue is left behind.

What is Brake Fluid?

Brake fluid, in contrast, functions primarily to absorb moisture within the brake system, ensuring safe operation. Typically, it is glycol or silicone-based, designed to protect and lubricate various metal components. While it does transmit force effectively, it is not intended for lubrication in the same way as power steering fluid. Thus, the properties of brake fluid make it unsuitable for power steering systems.

Consequences of Mixing Brake Fluid with Power Steering Fluid

Adding brake fluid to the power steering reservoir can lead to significant damage. Brake fluid is more abrasive and alcohol-based, potentially eroding rubber seals and hoses within the power steering system. This could result in leaks, diminished steering performance, or even system failure. Therefore, it is critical to use the correct fluid type in your vehicle’s systems to ensure optimal performance and longevity.
