When I installed new brake drums on my 1995 Ford Escort wagon babe magnet, I wiped the inside of the drums out with acetone to remove oil that may have been used as a preservative on the steel. However, not much of anything came off onto the rag. Should I have used something more abrasive? My concern is that any preserving goo is now imbedded in my new brake shoes. Comments?
Different manufacturers use different kinds/amounts of preservative on their brake products. I’ve seen some with next to nothing and some with a hard coating of sticky stuff.
I’ve usually used brake cleaner or just plain soap and water to remove the coating prior to installation.
I’m sure that you are fine with what you did.
