please dont laugh, i had a bad experience when i was a kid with heat/fire, so anything i feel hot i get nervous, here goes, my rear drum brakes never really grabbed before and i finally adjusted them with some new drums also, theres drag on the wheel now when i turn the rear wheels, but is there a thing as too tight? i thought going in reverse and hitting the brakes will self adjust them? if they are tight what will happen? i have to drive on the highway 32 miles tomorrow, the car stops fine now compared to before and i feel safer, also one of the rear squeeks when i hit the brakes now what would cause that? thanks guys
