Likely need to replace all four after a wildly botched wheel and tire job courtesy of a tire shop in New York near Lebanon Valley. So many choice words for them. However, are there any out there that are reproduced?
Nope. You'll have to send your out to get relined. JG Relining is the place to send them. Your not going to like the price. I think they run $300 a drum
Is it possible that the aluminum drum could have been bent? That is currently what I assume is going on, cause the lining is fine. The way that the shop did the wheel mounting is that they put weights on the inside of the 852 rims, which contact the fins of the drums on all four wheels. When going down the road right after the swap, when hitting the brakes, the whole car shuddered and felt like it was rattling apart because of some issue. Is there a chance that the pads are worn irregularly, or since it started as soon as the drums got "bent" (is that possible) should I look into a used set of drums around here?
I'd look into having yours turned before replacing. Likely there is plenty of meat left. Step one is to yank the weights and reinstall.
I yanked the weights the second I figured out they were the issue, 10 months ago. Whats the likely cost to get them turned? Also Jason, what do you think about this? https://www.carid.com/1967-buick-riviera-brake-parts/qrp-brake-drum-100951652.html
So all 4 wheels are now squarely seated on the drums and lugs are torqued? Just as a test, you could try stopping the car by applying the E brake. That way you can tell if its in the front or back or all 4. If it stops smooth on the E brake, you narrowed the issue down to just the fronts
Hmm thats pretty wise, great idea And yes, fully torqued and seated, but I certainly want to check again, even though I've taken the wheels on and off at least 5 times since then
Problem is that most shops just replace rotors and drums these days. They're so cheap that it just doesn't pay to cut them anymore. I bet most of the younger techs working in shops don't even know how to cut a rotor, much less a drum. I notice brake lathes when I visit shops. The ones I do see, look like they haven't been used.
It might take a little sniffing around but he'll find someone to do it. It's not a lost art. I'd start there before dropping huge money on NOS units or repops..
Rest of the rear drum is perfectly round, now look at this spot. Could it affect anything or am I overexamining?
Also, curious about the torque spec for the lugs on the Riviera. I’ve been using 90 ft/lbs, what should I be using?
John if your drums were bent or way out of balance they would vibrate all the time when rolling- not only when the brakes are applied. My advice- replace the shoes and hardware. Your shoes are junk. Normally i reuse the hardware but I've had weak springs cause the shoes to slap. have your drums turned. When they are mounted on the lathe that will tell you a lot. The way the carbide contacts the surface as it's spinning will be a dead give away if one is fubar.
Hey John, I'm not Jason, but my guess is that the drums in the ad you posted are not Aluminum. If I had some new Buick Aluminum drums. I'd be looking for a lot more then the ad price for them.
