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.
The open plain allows the water to slow down and spread out, leaving alluvium behind. As the water slows down, the harder-to-move pieces of alluvium, usually the boulders and gravel, are the first to stop. Further down the alluvial fan, the lighter sediment, like silt and sand, is deposited. Alluvial fans have some similar characteristics. The pointy part of the triangle, where the water and sediment have come out of the narrow passage, is called the apex or sometimes the fan head. The bottom part of the triangle, where the mixes spread out, is the apron, or tail, of the alluvial fan.
