Bad Brakes = Bad Suppliers
I work for a chemical company that supplies metal pre-treatment products to a number of companies that make brake pads, drums, calipers, etc. You would be surprised and a little scared if you saw some of the parts we received that have defects on them. There are four main companies in the US that supply most of the brake pads and calipers to the OEM market. They all have tight quality control procedures in place, but sometimes parts still slip by. The worst I saw was a Big 3 car supplier who had 35,000 sets of front brake pads where the pad pulled right off of the metal backing. They either forgot or didn't clean all of the stamping oils off the parts before putting on the adhesive. Wouldn't want to be one of the unlucky ones who got those. Once a batch of parts go out, if they see a problem they recall them and attempt to re-work, but if some are sold, they play the game of "hide the weenie" and hope the ones sold don't fail. The testing takes about three weeks to really see how well the parts were treated, so the parts are almost always on the shelf when they find a problem. Scary!!!
