Bonded or Rivited?

-
Riveted. Bonded can become unbonded.
 
Bonded, if you dont pay attention, the rivets will grind into the rotor. Ask my neighbor about not paying attention to squealin and grinding.
 
That's why you pay attention.
 
I ask this because I've had problems with both (especially several years back when all I drove were old Mopars with drums all the way around, 72 Dart, 68 Satellite)
I've seen them crack and separate at the rivets, and had them become "unbonded" at the ends.

Do you think it matters whether they are remanufactured rivited or bonded VS new?
 
I sold auto parts for 15 years in a previous life. We carried traditional name brands, BEFORE stuff became third world'd. Raybestos, Wagner, Bendix if we could not get the first two, etc

In that 15 years, I don't think I saw 4 shoes "come back" unbonded. It just might be that when rivets come loose or lining becomes unbonded, the lining is ALSO toast, as it might have been caused by immersion in water or really severe heat or other such causes.


Part of my job was turning drums and rotors, and I've turned THOUSANDS of 'em. Kwik-way rotor machine, like this one

old red Van Norman drum lathe, there are no photos of it, they've all been turned into fossils by now,

and later, a new Ammco lathe.

I've also "spent some time" stompin' on an all manual all the time rivet machine for things like jammer and winch brakes that needed to be re-lined They are no 'dam fun. You get to spend a lot of time on one foot

And let's not forget the asbestos dust generating machine of all time, the arcing machine

I should have mentioned.... I only noticed lining issues (bonded or rivited) once the shoes were nearly toast. I've never had shoes come apart when newer, regardless of how they were made.
 
Never bonded on a vehicle that launches a boat! ... that typically unbonds them...
 
I have always read that riveted is better. However, I think bonded allows for more lining wear. With riveted, you can measure exactly how much is left before the rivets start gouging the drum. With bonded, it seems you can't judge totally from the side view thickness since there are hidden ridges that protrude into the lining and hit the drum first (wonder how I know).
