Most of the stoping power comes from the front brake...70%...Even though you don't drive fast..Going at 35 MPH and someone makes a lefthand turn right in front of you' Will need that front brake....If you get in the habit of Not using the front in an emergency you won't be able to get to the front brake in time...I ride when in traffic with two fingers covering the front brake...So i can apply the front brake without having to think about it....
