I've owned my 2003 Jeep Liberty Sport for not quite a year now, and have had nothing but rear brake trouble since the purchase. I've had it back to dealer several times with rear calipers sticking. They keep doing everything but replacing calipers. They put new pads and rotors on at a cost of 400.00 , after I told them it was the calipers. Now only a month into the new repairs, the constant chirping of the rear brakes has once again raised it's ugly head. I know damned well it's the calipers. I'm not a mechanic, but is there any way to lube calipers? If so , with what? How much would new calipers cost, and would they end up doing same thing? I don't want any more parts from Chrysler Jeep. The rotors they put on are as junky as the first. I'd sooner buy after market calipers, but would sooner save the expense if someone could tell me how to lube calipers. Any info is greatly appreciated.
