Long Travel Soft Brake Pedal

You certainly have read lotsa threads, good job.

Adjust the rear brakes till you can JUST feel them drag .
Set the emergency full on .

How's the pedal?

The first pump usually takes up any unadjusted travel to get the rear shoes out to the drum, once they contact the drum, - the second pump is when you feel pedal/resistance.

Setting the emergency, moves the shoe out mechanically into contact with drum, - then, when you pump the pedal, the hydraulics move the rear cylinders pushrods out to the shoe.

The springs can't pull the shoes back cuz the emergency is set, so all possible fluid movement should cease = hard pedal. If bled properly .

You got this.
