Practice full on front and rear braking Gina. Get comfortable with the process so it becomes instinctive. It helps to have someone watch you, at least until you know what the rear brake locking up feels like (you don't want this). A locked front is actually much easier to deal with. Simple sensory input-output here. Hands are much more dexterous than feet. It's much easier to judge how much brake you're applying with your fingers. Might just save you another nasty meeting.
