Does improper adjustment cause rear brakes to squeak? On the road, mine are fine. At slow speeds though, (ie parking lots) mine squeal and drive me NUTS! I've cleaned everything, shoes are almost new, drums are smooth (new a couple years ago), and I've lubed the adjuster stars- they were kind of binding. Any suggestions?? I've also got a clunk under my feet somewhere when left front wheel hits a bump in the road. Can't find ANY suspension/steering parts loose or anything. Could rotten sway bar bushing cause this???? GUZZLES GAS BUT IT'S FREE AND CLEAR!!!
