1 Swap in a new set of shoes, reconnect the brackets & springs, put the drum back on and youâre done.  Thereâs no need for compressors, or opening fluid lines to retract pistons with these setups. As a matter of fact, replacing brake shoes on some vehicles can be accomplished in under 2 minutes, once the drum is removed.
The bicuspid valve, sometimes better known as the mitral valve, allows blood to flow in only one direction (assuming it is functional) from the left atrium to the left ventricle, it prevents blood from flowing back from the left ventricle into the left atrium.
The tricuspid valve forms the boundary between the right ventricle and the right atrium. Deoxygenated blood enters the right side of the heart via the inferior and superior vena cava.These are large veins that transport deoxygenated blood from the body back to the heart.lood collects within the right atrium, and it must flow through the tricuspid valve in order to enter the right ventricle. Then, blood exits the heart via the pulmonary artery, which transmits blood to the lungs for oxygenation. The term tricuspid refers to how the valve is constructed.
