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 purpose of the valve is to close when the ventricle pumps blood â¦ into the pulmorary arteries that lead to the lungs. The bicuspid valve, or mitral valve, functions similarly to maintain blood flow in one direction only. The bicuspid valve is located on the right side of the heart.
