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.
Power steering fluid is as vital to safe driving as oil is to continued engine prowess. Without this vital fluid, your power steering will fail. If you have a power steering leak, you may not be able to turn the car with the force needed. This can lead to unsafe driving situations and, worse, preventable crashes.
