How are the duralife rotors working out for everyone? Mine keep warping, they have been reground twice once at 10k and again at 27k. Now I'm at 32k and they are warped again. Should these be recut or replaced?

Mine have a little warp too

Thought it was pad deposits at first, but won't go away

I thought the same thing the first time. I wonder if this treatment process is simular to case hardening)? if it is than by resurfacing the rotors they have taken the hardened surface off.

Once they are wrapped they are always wrapped. Turning them will help temporarily, but the shake will return. Replace them, and make sure not to over tighten your lug nuts. This was an issue on my 08.

 

Highly doubt the dealer will cover them under warranty as brakes and rotors are a wear item.

On my 2000 I had a dealer cover rear brakes at 18k miles. They were toast. At 48k I did another rear change. Never touched the fronts

Rear brakes must have been dragging? Usually they'll outlast the fronts by a long shot.

Replace them, I never get rotors turned, only replace them. You've had it done twice, they are at the low end of spec I'm sure

Nope the rear disc design and harsh weather (salt/snow/etc) created the wear. The ended up added a shield to help a few years later

 

One main reason why they went to rear drum brakes again mid 2000s

Yeah that's what I was thinking, both times the dealership did it under warranty. I'm going to call and see were it gets me.

Doesn't gm make a performance brake upgrade for our trucks?

If they do you'll be paying out the rear end for it lol

Wow. That is very very short life. Mine has 35k and no signs of warping. My dads 99 Z71 rcsb has 120k and the brakes have never been touched. No issues at all.

      Acceptably cheap tires?

      By Atlas · Posted

      Which one, the AT or AS?   Starfire is made by Cooper/Goodyear but at $85/tire I'd think I'd need to level-set my expectations that they may not even be round 😉 But you're saying they're decent?   I'm already into this thing $1506 in parts, fluids, etc. Totaled all my receipts today. $250 of that was replacing an EGR and MAP sensor that were probably fine, but I'm not going to return the parts since they've been installed. I'm cheap, but not that cheap. I use it, I keep it!   I may or may not make money if I sell the truck at this point, but, that wasn't really the point. And if I billed my time, I'd be hosed for real. My thought on the tires is I "might" put 1,000 miles on before selling it. I just don't want to put absolute junk on it, that doesn't do anyone any good. If the Solus solidly isn't junk, I'll definitely consider them.

      Is your l8t engine bay super dusty?

      By rjgvt · Posted

      I leave mine as is. I'm always a trip away from riding on unpaved roads. Dealer can clean it when they prep it after I trade it in for another new truck.

      I have these on two vehicles and love them. Pepper is one of them 😉

      4WD. Far as I know it came stock with P's and not LT's. Definitely planning to put P's on it, but stock is a 109 XL load rating so I should probably stick within that guideline.   No rebates on anything I can see at the moment. Discount Tire is offering $50 off, but Pep Boys is very competitive on price, and also carries all the off-brand stuff. Les Schwab always wants an arm/leg, but they do good work.   It still has the original spare. Goodyear Wrangler RT/S, thing looks like a tractor tire LOL!! How times have changed.

      2020 Sierra 2500 windows rolling down

      By JohnRoy · Posted

      2020 Sierra 2500 HD (base model) gas engine 4wd.    All 4 windows roll down on their own. Happens somewhat randomly after stop and engine off - when engine turned off, when walking away from vehicle before or after locks activated. Pulled the window fuse F14 Instrument Panel Fuse Block Right; the driver's side still activates from driver's side door panel; passenger and back seat windows activate from local switches on their doors but not from driver's side group of switches. Power mirrors don't activate with fuse removed either (same fuse for both circuits). Problem not solved.    How can they even activate with fuse removed but they are all still opening and can control from each door?  When they open on their own, I can shut them from the switch in each door, but they don't stay closed.    Seems to be activated somehow with key fob; something bumping the key fob in my pocket or just handling - removed key fob and took it far enough away and now the windows stay closed. Replaced key fob batty just in case, no change.    Sounds like some kind of wiring short or maybe electronics. Dealer will first replace electronic control module without checking anything else and I anticipate problem will still exist since their troubleshooting skills are limited to "do whatever the computer says".  In any case, keyfob seems to be activating the circuitry.    Surely I'm not the only one with this issue, but I can't find anything related on the site. What do yall think?   JohnRoy
