Is Brake Fluid the Same as Power Steering Fluid?

[McElliot]

Brake fluid and power steering fluid are not the same. Brake fluid, also known as hydraulic brake fluid, is a functional liquid in the vehicle's braking system that transmits pressure to enable the braking action on the wheel's braking system. Brake fluid does not undergo chemical reactions, is unaffected by high temperatures, and does not corrode, soften, or expand metal and rubber components. The consequences of not changing brake fluid for an extended period include reduced braking force, the formation of vapor lock in the brake lines affecting braking, corrosion of the brake lines, damage to internal valves in the anti-lock braking hydraulic assembly, and wear of the rubber cups and pistons in the brake master cylinder, leading to contamination of the brake fluid.
