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.
bicuspid valves prevents the backflow of blood from the left ventricle. because there are two ventricles in the heart, left and right. the left one consist of oxygenated blood and the right one consist of deoxygenated blood so it will not mix up thru the present of bicuspid and tricuspid valve.icuspid valves prevents the backflow of blood from the left ventricle. because there are two ventricles in the heart, left and right. the left one consist of oxygenated blood and the right one consist of deoxygenated blood so it will not mix up thru the present of bicuspid and tricuspid valve.
