i am in the process of puttin a 6" lift on my '87 f-150 and while i had the rear wheels off i thought i might as well go ahead and check the brakes (drums). i got the cover off the driver side brake fine but on the passenger sade the cover thingy wouldnt come off, it felt like there was a spring holding it back, i have rebuilt many drum brakes before and didnt have anything like this happen. any help would be appreciated. thanks
