Re: brakes. it's not that, so what is it?

bleed them more , put a pint or so of fluid thru the brakes , bleed with
engine running and servo on .

if they are new drums and shoes they will need bedding in for a week or so
before they lock up nicely, they will be soft beforehand for a time . .

hold brake pedal down under pressure and see if it slowly moves to floor, if so
perhaps theres a seal leaking in master cylinder and fluid is going between
sections in cylinder rather than out of it , thus a master cyl repair kit or
replacement cylinder reqd ..

check rear wheel cylinders to see if any are seized up , you may have adjusted
the brakes but do the cylinders work ok.

i doubt it will be brake hoses causing the problem if they are in good
condition .

they are double lined and if the inner is split youll see a small lump appear
somewhere along them when brakes are under pressure, just run fingers along the
hoses carefully to check them when someone else has applied brakes for you .

It does sound like the rear brakes are out of adjustment or have air in
them. The other possibility is that the drums have been machined
oversize and have standard shoes fitted.

I'd go with the sticking slave theory on the rear.. or sucking air in. For
all the faffing probably worth replacing both the rear cylinders.

If the drums and shoes aren't the same radius they will only touch in a
small area, which is enough to lock them up on the adjusters, but when
the full pressure of the hydraulics acts on them the shoes twist &
deform giving a useless brake pedal. It's probably well worth popping
the shoes off and checking that they actually contact full length in the
drums.
