<VV> brakes

[robert guerin]

my brakes on my 65 corsa are not operating right.the pedal moves about 
the 1/4 " play but then becomes hard but very little braking effect.it 
acts as tho they are glazed.i have been able to lock them up if i really 
put alot of pressue on them.i have taken the drums off and sand them as 
well as the shoes.no change.anybody got an idea what could be wrong.
