low quality front brake rotors

I just noticed that one of my truck's front brake rotors is getting grooved pretty bad. At 4600 miles! The other rotor looks OK. I have never seen this on any of my vehicles at such low mileage. Not even at 90k miles! Are these rotors junk, or what? Would warranty cover it? I want this crap replaced, not turned. Will dealer do it? Any recommendations for better quality aftermarket rotors/pads?

My rotors lasted 160K miles on my 2000 Sierra Z71.

I'd guess something got between the pad and rotor or there was an issue with the brake pad somehow.

 

That won't usually be covered under warranty.

 

OEM brake parts are perfectly fine for these trucks, I recently replaced everything with Powerslot rotors and Hawk brake pads from www.buybrakes.com because they were a little cheaper then my cost for OEM parts.

Hate to jump the thread, but I would really like to know how you like the Powerslot rotors and Hawk pads. I am looking to upgrade my Yuk and wanted to know if you really could feel any difference?

I'll ask my local dealer. GM warranty I believe covers adjustments and all defects, even on wearable items within something like first 12 months/7500 miles. This includes brakes, tires, alignment, wipers, and engine belts.

Well, that was back in 2000. They may have been using much better quality brake parts back then. i know a guy with a 1996 Impala SS with about 120k miles and still very serviceable original brake pads on original rotors.

I did some forum searching and found this thread:unhappy truck owner

 

Almost the same problem as mine occurring at almost identical mileage. Which leads me to believe that late model GM truck rotors are crap. It's that simple.

My rear rotors were completely rusted on the surface @ 15K miles. Dealer machined the rotors and installed new brake pads under warranty.

So far so good, no squealing.

They stop great. Better then OEM, not sure, but I'm happy

It isn't that simple, because a few people had a problem, they are all crap?

 

Hit your dealer and let us know what they say :ughdance:

All OEM type rotors show rust on them at some point or another, Hell, new cars and trucks on the dealer lot can show rust on the rotors, that isn't a problem.

My 2004 has 65k on the orginal pads & rotors. Not that crappy IMHO.... The rotors are NOT stainless steel and will get surface rust on them if they sit for a couple of days and it rains.

My 06 z71 has 15k on it and no grooves in the rotors at all. Id say over 60% of those miles are towing my boat too.

 

So they arent all crap.

My 98 1500 2wd had warped rotors within 3000 miles. Turned by dealer under warranty. Lasted another 2000 before pulsating started again. Had aftermarket rotors installed by an independent shop and no further problems up to 24,000 when I traded it in.

 

Traded the 98 in on a 2000 S-10. Rotors warped within 7000 miles. Dealer turned them and warped again within about 3000. Same drill, had shop put on aftermarket rotors, no further problems.

 

My 2001 Z-71 I bought used, had warped rotors by 30,000. Went to aftermarket again, no problems. My shop (experienced techs) said the OEMs were very thin and warped easily.

 

Now have a new 2006 Z-71 GMC. At 5200 miles, so far so good. I had brake problems with my wife's Malibu, warped at 25,000. Aftermarket rotors cured it for another 20,000 miles. Traded it for a 2006 Honda Accord. I bet my brake problems with my wife's car are over!

      2 speed transfer case optional now?

      By newdude · Posted

      This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.

      Different requirements for oil filters?

      By newdude · Posted

      2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.

      Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉

      2020 Trailboss 6.2 replacement

      By newdude · Posted

      Probably not their first rodeo, so it should go as planned most likely.  Typically the service manager or tech doing the swap will put some seat time to shake it down after they get it all put back together.  We usually put 50-100mi before we hand them back so if something happens, its not after you get it.  A coolant leaks, oil leaks, a ground left off or loose, vibration, etc.     The new engines so far have been good?  There's been a couple that have popped out there again (the replacement engine) but most have been okay.
