I own a 2006 2500 HD Silverado with 6.6 Duramax LBZ, single owner. I am at 150K mark and getting ready to do all my fluids once again. Had brakes inspected this morning at local "Brake Masters". They said brakes were good and should give me plenty more milage. Now at 150K on original brakes. I know that supposedly these are monster size beakes from factory. Does seem okay to you guys.
