Yes it can, depending on what amount "a tiny amount" is. The fluids in cars today are specifically designed for their purpose. Brake fluid is designed to withstand heat (minimal expansion when heated), absorb moisture and interact with other materials such as rubber and does not lubricate like Power Steering fluid does. Lubricating oils (engine oil, Power steering fluid, Grease) attack the things they come in contact with making them slippery, but in contact with things like Rubber seals, the rubber will expand and sooner or later cause a failure.
In some cases, yes but NOT for hydraulic BRAKE fluid.
hydraulic brake booster (power brakes)
Yes, This is part of hydraulic system
designed for hydraulic jack perhaps power steering fluid would work Brake fluid Ruins pump
For several years of the Chevy astro van had a power brake and power steering system that was linked together. Instead of a brake booster, the power steering pump provides power to the power brake system. Often, if the brake pedal would become hard to push, it is a power steering pump problem. Change the power steering pump and the power steering fluid and your problem may disappear.
NO. In most vehicles the brake fluid is different from power steering fluid. It may work for a while, BUT is it worth taking risks with your brakes. Your life may depend on that.
The master brake cylinder has nothing to do with the rack and pinion steering. In some vehicles the power steering box and the power brake booster share the same hydraulic power assist system.
The brake system and the power steering system.
The connection between the power steering to the vacuum hoses is called the hydraulic brake booster. It supplies the vehicle with fluid pressure from the power steering down to the hoses.Ê
It is the same thing as the power steering pump - front of engine, left (driver's) side, driven by a single belt. It provides hydraulic pressure for the power steering, and for the power brake booster. Some Eldorados have had the hydraulic booster changed out and replaced with a vacuum booster; this is not factory setup.
