Hey guys.

I need new drums for my brakes.. my current ones have been over-machined. They are standard LC 4door setups.

I'm going to check out an LC or two in wrecking and i need some pointers on how to recognise drums with sufficient thickness/life left in them. Can you tell by eye? What are signs of over-machining.

Any help is appreciated! Thanks

You need to meause them. New ones are made by DBA and RDA. RDA are cheaper.

There is a chamfer on the drum when you look inside where the shoe sits...... if that is gone discard
If its there measure
9" is std (228.6mm)
