Stomach ulcers are sores that form in the lining of your stomach due to erosion of the protective mucus layer. Bacteria called Helicobacter pylori or long-term use of nonsteroidal anti-inflammatory drugs, such as ibuprofen and naproxen, can cause this erosion and expose the lining of your stomach to harmful digestive juices.
Nothing good. Brake fluid is usually much higher density hydraulic fluid as well as different type than is power steering fluid. In vehicles with ABS systems it will damage sensors and seals, and in any vehicle it will result in spongy, poorly operating brakes and damaged seals.
Pouring in the wrong fluid or overfilling the system can cause expensive damage. The mechanic will need to consult the vehicle owner's or service manual. If the fluid is low, the mechanic will check the hoses, fittings, and clamps for leaks. Empty the power steering reservoir. Fill with the correct type and quantity of new fluid. Bleed the power steering system/clean up any residual fluid. Test operation of power steering. Check for any power steering leaks.
