Manual Transmission Question

Hey guys, gotta question about manual transmissions in general that I've never been able to figure out. Why is it on a manual when you hit the brakes without pressing the clutch the engine dies? Just curious thats all. Thanks.

Hitting the brakes won't necessarily kill your engine with a manual transmission. If you come to a stop or slow down enough in a higher gear you probably will though.

Clutches and pressure plates make a solid connection from the input shaft of the transmission to the flywheel of the engine...nothing is supposed to slip like in a torque converter for an automatic so when the output shaft of the transmission stops, so does the input shaft. People avoid stalling the engine by pressing the clutch or putting the transmission in neutral. This allows the flywheel and pressure plate to spin freely at whatever rpm the engine is at and the clutch disc and input shaft are spinning at whatever speed suits the transmission.

Like dmc12mk3 said, by keeping the clutch out you are keeping the load on the engine but because your breaking, the RPM aren't being sustained and thus the engine dies. Almost like having your idle set so low that when you put it in gear (and create a load) your engine dies.
