so, i just checked all my drum brakes on my 77fj45, and set them all so they're pretty even, but it still pulls hard to the left. so hard that when i drove it illegally the other day it almost pulled me into on coming traffic! 
so im wondering, do i just have to bleed the lines on the one week side? could it be something wrong with the master cylinder? has anyone had this problem before?
also, the wiring. i was having trouble with lights working in mysterious ways when i first bought the truck, and some guys said, check the grounds. so i did, and as it turned out the ground on the right tail light was missing, so i grounded it and everything worked perfect. problem solved.... worked ont he truck for a couple months, started it up, and now the lights are all funky again. the ground i put on didnt come undone. so whats up? more ground problems? should the left tail light have its own ground, cause it has no place for attachement like the right one did. any advice is appreciated thanks.
