I was replacing the ads on a 01 explorer sport today and after going to auto zone twice the pads I got didn't fit. They were the dura last gold part# dg833 I think they were. The guy I'm doing the work for wants me to come and finish them tomorrow but I need to know what pads to get first. Is there a certain type of pad to get I'd hate to go return the pads I got now just to have the same problem happen again. Can someone tell me if there is a certain brand pad I need to buy and if so where can I get them and what are they.
