worked on a friend of mine subi in north idaho the other day to fix his brakes that locked up on him, found out it was the hill holder valve ad the cable was all out of adjustment got that fixed along with a new front passenger side caliper now it all works but he has to pump it twice to get it to stop so i bleed the system kitty corner like the book says no more air but the brakes are near the bottom so he is going to check the rear brakes in the morning told him maybe need new drums and rotors as they are the originals and they have been locked up and gotten very hot but due to money costraints he has to put it off. its a nice car for 250 bucks starts up ad runs nice just has brake problems.

bleed it some more and make sure there are no leaks. 

 

rear drum cylinders can leak.  rusty brake lines above the gas tank, but i'd imagine you don't have much in the way of rust to worry about out there?
