Bad Rear Brake Drums from Napa
 

I recently had new rear brake drums and brakes installed on my 99 dodge
caravan.They made my van shack like hell braking down hills.A second set of
drums were installed and they vibrated more than the first set.All the
other brake parts are fine.Has any one else had problems with Napa brake
drums? These were Made in China and they were the more expensive drums.

I had bad disc and drums from NAPA, O'Reilly's and Autozone. I now ask them
to turn them before I bring them home. Several had high spots that would
have caused excessive vibration and wear even brand new. Have the drums
turned should solve your problem.

It makes a big difference where and how to store these drums/disk on the
shelf, they can warp in the box beleive it or not

I'm talking experience Bill, Our parts department used to stack rotors and
drums on top of each other, several together. We would install them and find
the pulsation was really bad, we were charging the parts department the
labor to machine them.. then they finally got smart and stored them
differently and the warped rotors and drums stopped. not sure if the
shelves they had them on were flimsy and caused this, you would have to ask
someone who specializes in metal that question.

Drums are to be stored flat, not on edge. Rotors to be stored on edge,
not flat. Used to be the boxes were labelled.

That said, chinese metalurgy leaves just a wee bit to be desired - and
it is not out of the ordinary to have drums that are round when cold,
and eccentric when warmed up.
The Canadian made drums and rotors are quite often much better
quality, but it is not unheard of to have bad ones from ANY
manufacturer.
They are finish ground while still "green". In years past, they were
"aged" before final machining/grinding.

All it takes is for one person to drop the drum once after it's made
and it's instantly out of round. It's always a good idea to turn any
new drums when you get them.

Sometimes the same thing can be said for rotors.

Bad Rear Brake Drums from Napa
 

2016. Bought rear brake drums from Oreilly. They were warped. Got another set also warped. Absolute garbage. Got a set from Napa. Also warped. Taking them back. These are on a 94 Chevy pickup C1500. Put the old drums back on and they are smooth. China. Never had problems with brake parts from these stores before.A bad run maybe? It is a thorough pain doing this numerous times.
