First is what shoes did you use?My kid had a shop do the brakes on the 66 Charger and they were crap because of the linings.I used to run notjing but NAPAs best.Now I run Advanced best.Drums should have been truned at least for a clean up.If they arent bad a 3M rolox disc on a die grinder will clean them up but they must be cleaned real good before install.My ? is whay run drums Unless its a show poodle or rare change to frt discs.You will never look back.Oh yeah I did brakes almost every day for 30 years as a tec.Rocky
