While we compared brake fluid flushing to oil changes earlier, this service doesnât need to be done as often. You can change the fluid out every three years or about every 24,000 miles, whichever comes first. When you do get your fluid flushed, be sure you are using the right kind of brake fluid.
Windblown deposits of mineral-rich dust and silt is called loess. The term comes from the German word Loss and from the Alemannic word losch which means loose.
Silt clogs vital shipping channels. Silt is a solid, dust-like sediment that water, ice, and wind transport and deposit. Silt is made up of rock and mineral particles that are larger than clay but smaller than sand. Individual silt particles are so small that they are difficult to see. To be classified as silt, a particle must be less than .005 centimeters (.002 inches) across. Silt is found in soil, along with other types of sediment such as clay, sand, and gravel. Silty soil is slippery when wet, not grainy or rocky. The soil itself can be called silt if its silt content is greater than 80 percent. When deposits of silt are compressed and the grains are pressed together, rocks such as siltstone form.
