Just received a set of ACdelco 17d8 brake pads. They are bonded now not rivited . Any issue mixing them front and rear. Ok found some info on NCRS site. The 17d8 riveted are made in Canada and are organic and the bonded ones are made in Mexico are non ferros ceramic. Both of my boxes are made in Mexico with same part numbers ac and gm. but the box with the bonded pads says non ferros ceramic.

 

forgetting for a moment the writing on the box and riveted versus bonded, does the friction material appear to be the same on the two sets?

 

No the compound looks different. Tried to get an answer from delco and they sent back that they don't have access to tech info. Probably wrong department. think they

 

GM sold off most of their component divisions (and the engineering expertise) about twenty years ago. GM kept the Delco name/trademark though. Today, Delco is just a pass-through organization that buys stuff and puts them in their familiar design boxes. You're kind of on your own figuring out if the part in the box is going to be as good as the original Delco replacement parts that were originally on your car.

 

Just received my service grade 14d8 ACdelco pads and they are non ferrous ceramic. WTH

I would not recommend mixing pad types between front and rear. If you are changing pads, change all four if you cannot get the same type as you have now. There can e HUGE differences in friction between different pads. If you have such a difference in braking between front and rear it can be dangerous.

 

I agree. With the relatively low cost of brake pads why risk it?
