oky doky, then un-adjust the front brakes (again) ,,, but when you do it, it does pay to check that the cyl pistons/shoes have gone fully home properly buy pulling the drums off & looking to see that the cam-adjuster has come away from the shoes, & even then you can physically push the shoes back home while you`re there (if your return springs are a bit sad)
then once you have made sure that the shoes are fully home (un-adjusted) then let the nipples loose & watch for air bubbles but keeping an eye on the reservoir.
if you have early tin tank reservoirs then the recovery hole (inside the tank through to the cyl) is only about an inch down the reservoir,,, so you can`t let the level drop much or you`ll be sucking air again
if they`re the later plastic type then you can see the level getting low,,, keep it topped up.
once there`s no more air coming by gravity bleeding then you can adjust the front brakes up
adjust them up until the wheel locks up & then back them off a tad until you can turn the wheel relatively free but still here/feel the shoes scrapping/rubbing the drum slightly
Now!!!---> to un adjust: if you can imagine
being under the car , looking forward... the left wheel adjusters need to be turned anti-clockwise (ie: in the rearward direction of rotation of the wheels)
the right side (drivers side) need to be turned clockwise (in the reverse direction of rotation of the wheels)
then gravity bleed
then to adjust them up you will need to imagine you`re under the car again & the left (passengers) wheel adjusters need to be turned clockwise now (following the forward direction of rotation of the wheels),,, the drivers side (R/H) wheel adjusters need to be turned anti-clockwise (again in the forward direction of rotation of the wheels
if you don`t follow this procedure the right way,,, IE: if you adjust them the wrong way then the return of the shoes will un-adjust the brakes each time you use them.
once this sequence is sorted correctly you can simply bleed the rear brakes (whether they`re adjusted up or not),,, then adjust them up if they`re not already
the rear adjusters are simply a square headed, r/h threaded bolt, with a pyramid end wedging the shoes apart,,, so you wind them in until you lock the wheels up & then back them off until you can turn the wheel free enough but still hear/feel the shoes scrapping/rubbing... don`t leave the wheel tight to turn.
you can pump fluid through with this early system but i prefer not to as you may find that you can areate the fluide if you`re a little too enthusiastic with your pumping
if you have a small leak somewhere tho,,, you can find that air will happilly suck in & fluid may not leak out,,, so leaks "May-Not" be that obvious at first
sometimes it takes a good drive over some bumpy roads & get some knocks & bangs to disslodge some air bubbles off the dry internals,,, once they`re in solution & not stuck to pipes/hoses you may find you`ll have to repeat the whole process to get them out too.
I`ll just run over the design problem causing the need to un-adjust the front brakes again, just for those who don`t realise,,, & also for those who "think" they know but some obviously don`t

the front cyls are mounted vertically,,, so if the piston is protruding outwards from it base, then air will be trapped above the bleed/connector pipe hole,,, air is lighter than brake fluide so no matter what you do,,, however you bleed it,,, the air simply will not want to go down to get out of that hole
you`ll need to make sure the pistons are down , home, totally, fully,,, all the way
only then will the bottom of the piston line-up with the hole for the air to escape
it`s just simple physics (Nature)
if fluide isn`t p!ssing happilly out of each nipple then you have a blockage & need to fix it first before going any further,,, more-than-likely a bad hose ,,, or poop in a nipple/cyl.
if you can follow what i`ve just typed then you should have awesome mini brakes & will be fine for yonks n yonks
until your shoes have worn some & you can simply adjust them all up again
if you still don`t have a decent peddle then you havn`t followed what i`ve just typed
or
you have a leak somewhere--> letting air in the system each time you lift your foot off the peddle... might be the master cyl sucking air in as you lift your peddle each time,,, or a piece of crud stuck in one of the fittings/tube nuts stopping a perfect seal... or your shoes are so badly worn that you`re adjusters are just going around & around & no amount of bleeding & adjusting is going to fix shoes that need to travel too far to meet the drum.
i always measure brake drums to see what size they`ve been machined out too

easy-peasy,,, get on with it
or just fit some discs onto the front

merry christmas everybloody
