Am about to do a front and rear brake job on the 99 Tahoe 4wd and was trying to get the "best" replacement drums and rotors. From what I can tell, if I try to get them from the dealer, I'm getting AC-Delco Durastop, which seems to be just a re-packaged Raybestos piece, albeit at a ridiculous markup. So, I decided to just go straight to Raybestos and ordered these from RockAuto. It seems there is no such thing as replacement drums and rotors made in the U.S. or Canada anymore from what I've been researching, so the label was disappointing, but not surprising:
What I do find unacceptable was the disparity in balance weight. Here are the two new drums side-by-side:
Here is a close-up of the "good" drum with the small balance weight:
Here is a close-up of the other drum with balance weight covering almost half the face of the drum:
As a comparison, these are some old pics of the drums which are on the truck now, which I believe to be original GM units, although I know they have been turned at least once. Notice the single small weight in the first pic (driver's side) and the two small weights in the second pic (passenger side):
So, needless to say, I'm NOT happy. It seems the hardest part about working on these trucks these days is getting decent parts, with practically NOTHING being made on this continent anymore. Actually, regardless of where it comes from, if there is an obvious quality control issue like this (such a drastic cast-in imbalance requiring this much weight), it's not going on any vehicle I work on.
So, this is going back (I just love paying return shipping for no good reason). I don't know if I should try to order another one or not. I used to use Wagner, but I had to buy several sets of rotors last time to get a pair which weren't warped BADLY out of the box, so I've no confidence in them. I believe Napa is actually Raybestos, so at least I could check it out before I buy it. Not sure what to do anymore. I might just try to turn these drums again, but really wanted fresh drums.
