Emergency brake delete

WRONG .

A parking brake should hold in reverse, dontcha think ?

How many times you backed outta a parking space, put it in drive, and not move an inch forward till you release the "emergency" ? ?

Shouldn't be calling other people dumbass while you continue demonstrating being one, dontcha think ? ? (obviously not) !
They do hold in reverse "somewhat" but not near as good forward, simply because the way brake shoes are made. The short shoe (leading) on the front and long shoe (trailing) on the rear, so they naturally hold about twice as strong forward.
