Rear brake rotors going out way too soon (on 3rd one)

I have a 2000 Silverado Z-71 with 142000 miles on it. Just did a brake job on it. Took the rotors to get them turned. The one for the right rear was out of spec, so they would not turn it. Had to buy a new rotor. The thing about it is I replaced that same rotor in 2003. This makes three rotors on the same position - original, 2nd one in 2003, and now this one. Does Chevrolet have a problem ? Or is it just my truck. If it is mine, what would be the cause of this?

Calipers are good and free moving. Are the factory rotors cheap ? I just find it odd that just on that one spot (right rear) has gone through 3 rotors and all the others are originals with no problems.

      Vehicle Payments

      By ChristopherDobson · Posted

      Monthly payment is only part of the equation. With today's prices and interest rates, I'd look at the total monthly cost: payment, insurance, registration, fuel, maintenance, and expected repairs. A vehicle that fits comfortably into your budget is usually the better choice than stretching for a higher trim. I've also kept my vehicles longer over the past few years. New cars have gotten expensive enough that driving one for 10+ years, while staying on top of maintenance, often ends up being the most cost-effective approach.

      OCI, not when but why?

      By Grumpy Bear · Posted

      10 Ford and Chevy engines proven to reach 300,000 miles   You may note a common 3K OCI on this list of gas motors. I skipped over the diesels. Dh'O.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By jake111 · Posted

      Thanks newdude!  By the time manual selection is needed, I'm probably too much of a control-freak to depend on the transmission sensing braking to activate automatic downshifting.  I would be anticipating the situation and already be manually downshifting.   This truck replaced a 2004.5 LLY diesel with the Allison 5-speed.  Putting it in T/H made noticeable differences (when the torque converter locked, upshift points, downshift behavior).  On this 2024 gasser with the 10L1000 I haven't been able to detect much, if any, difference.  Ok, I can never tell now when the torque converter locks up.  But I also don't notice differences in shifting.  For downhills, I've probably already manually downshifted by then anyway.  Since it's also more awkward (than the 2004.5) to engage/disengage I don't even bother.  Or maybe it doesn't really matter with just a 3k lb. camper in the bed?   Thanks also for the list of reasons the charging system might select various voltages.  However, what I am seeing doesn't fall into any of those categories.  It very definitely, and very consistently, rises after coasting/braking.  Maybe not immediately, but not very long after coasting/braking.  Very consistently drops voltage when no longer coasting/braking.  It might also be interacting with the camper battery charging (I might disconnect the camper and see if it changes the charging behavior).  I also need to recheck turning on headlights for when I want to force it to charge the camper.   Another JR, in June I converted the camper to LiFePO4.  Since it's not a good idea to try to charge lithiums directly using truck, I installed a Victron Orion XS DC-DC charger (which BTW is AMAZING!!).  Being cheap, I only had to buy that one item (besides the battery, of course) to do the conversion.  The camper OEM 120v battery charger (only 19 years old and works perfectly) and the truck feed the input to the DC-DC charger (not at the same time).  But I didn't want the camper charger feeding back to the truck so I kept the old separator.  I considered replacing the separator with a 30amp diode but that means more work and might add another 1/2 volt drop.  One thing that surprised me was the voltage drop over the long 10awg wire run, so I can only charge smoothly at 8 amps (because the DC-DC charger is completely configurable).  Another reason I don't want an added voltage drop with the diode.  I might also be a little lazy but all this work is being done under the sink with a small cabinet opening.

      cam upgrade in CA

      By davester · Posted

      apparently CA smog is (or at least was)  checking that the vehicle is using the oem and/or a ca smog approved tune, so I expect you'll fail inspection doing it.

      Possible lifter tick after DOD delete

      By davester · Posted

      yes, leaking exhaust will mess up o2 sensor readings, which in turn messes up fuel trims.
