more brake problems

["Bill" <wls11@scasd.k12.pa.us>]

i not only have rusty brake lines, but now my emergency brake 
snapped, too! i was parking on a steep hill (my driveway), and my car 
(81 4k, 5cyl) kept drifting, even with the emergency brake on and in 
1st gear.  the footbrake held it on the hill.  when i pulled harder, 
it snapped.  hopefully this is somewhat easy:), i dont have much 
time. are there any good sources to contact for the parts, or should 
i visit the local junkyard?

thanks, 
bill
