When you apply the brakes, brake fluid is forced under pressure into the wheel cylinder, which in turn pushes the brake shoes into contact with the machined surface on the inside of the drum. When the pressure is released, return springs pull the shoes back to their rest position.
Normally, protein is not removed when the kidneys filter waste from the blood. However, when the kidneys are damaged, protein leaks through the damaged filters and is removed from the body in the urine, along with the waste products.
Whatâs wrong with having albumin (protein) in my urine? One of the main jobs of your kidneys is to filter your blood. Your kidneys keep important things your body needs inside your blood, like protein. They also remove things your body doesnât need, like waste products and extra water. If kidneys are healthy, you should have very little protein in your urine â or even none. But if your kidneys are damaged, protein can âleakâ out of the kidneys into your urine.
