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 bicuspid, or mitral valve (also called the left atrioventricular valve), is located between the left atrium and left ventricle. It prevents any backward flow of blood duri â¦ ng contractions of the left ventricle.here are two valves in the heart. They are tricuspid valve and bicuspid valve.There is a possibility of the blood going back into the atria. This is prevented by these two â¦ valves, the tricuspid valve on the right side and the bicuspid valve on the left side.
