The problem with the rear disc was in the parking brake system. I guess GM found it easier ($$) to change it back to drums. The big issue with Vendors that work for the big automakers is this. Say you get a 5 yr GM contract to make brake calipers for lets say for simplicity $1000 a year. Well after the first year of production Gm expects a 8% decrease in pricing. So for the 2 nd year you are building calipers for $920a year. 3rd year is less then 4th 5th etc etc. I know for a fact that FORD does this to its Vendors. So if you take all that into account the parts are being built cheaper. The vendors start to cut corners such as QC and under qualified personnel. I worked for a vendor that shut there doors because of this. Over 800 people in a small town lost there jobs.
