This will show my ignorance, but where can I locate the factory part numbers for the brakes? And do the clips come with the pads or is that a delegate per number as well?
Thanks again for the help!

Go to rockauto.com and you can look them up as well as buy from them.  Or just get the part #'s and then compare to others around the web, Amazon, eBay, 1A Auto, etc. for the best price.

I tow with my truck every now and then and I just swapped out the OE stuff (not worn out at all) at 20K miles for Hawk LTS pads on new Centric Premium rotors.  Initial impressions are positive, but I will see how they do towing, and after a couple miles before giving my opinion.  I was told by the Hawk rep that the LTS provide increased torque and fade resistance over OE but are still friendly enough for a DD and they are supposed to be low dust also.

When I upgraded my 442 to dual piston front calipers and larger rotors 5 years ago, I put on hawk pads. That car now stops better than my old E46! I can’t speak anything about longevity because I’ve only put 5-7k miles on it in that time, but the performance is awesome. Not bad on dust either.

So here is my take.  After only a 1K miles or so the Hawk pads are different, but not super noticeable in day to day driving.  When bedding them and they were warm, both peak torque and initial bite were much better than the OE stuff.  However, in the morning when they are back to ambient temps they do not feel much different than OE.  The pedal feels a bit more solid, so that tells me that dont need as much pressure to work like the OE pad, but they need some heat to get the better feel.  While towing the car trailer I notice the truck stops quicker as they heat up (imagine a panic stop on the highway).  As the brakes build up heat the rate of decel during the stop increases.  I have not put enough miles on them to comment on dust or wear.

 

Overall, if you are putting them on for a noticeable feel they are probably not worth the money.  For a DD that sees some time towing heavier loads (car trailer, travel trailer, etc.) they are beneficial.  I can see them really shining towing through hills or winding mountain roads where you are more frequently using the brakes.  My tow this past weekend was all highway.

From another forum I visit (dieselplace), some people there think that the original pads last a really long time (like 150+K), but the replacement OEM pads only seemed go maybe 1/2 that....they were using GMT800 trucks IIRC...

I used to frequent

thedieselplace.com when I ran diesels.

It's true . I actually got almost 200,000 miles on the original pads and rotors on my 2003 2500 HD Duramax. Lot of hwy miles though.

The Allison transmission is the reason .

The truck will almost stop itself when you let up on it.

If you can't get at least 100,000 miles out of your brakes you either are riding the brake pedal or you go from speed to full braking without coasting.

Coasting is the key if you ask me.

This has been my experience.  My dad just traded in his 2006 2500 crew cab with 150,000 miles on it and he never touched the pads or rotors..

Doing pads and rotors on my 17 now. 64k. Pads had 50 percent left but rotors were grooved from the pads and severe pulsating when driving. 

 

Went with AC Delco severe duty stuff from RA. 

 

Rotors are coated and have subtle grooves in them. Pads will be delivered Friday.

Had luck with my 04 with OE pads front and rear and Powerstop drilled & slotted rotors. Overkill for daily driving - but eliminated the brake fade I was having with a trailer hooked up and could stop on a dime.

Certain OE brands (such as GM) actually have two levels of pads. The pads that the cars/trucks come with from the plant are ridiculously expensive so you usually aren't even offered those as an option compared to the usually stocked cheaper still GM made sets. So yes, sometimes if not most you will see a difference in life of the pads with replacement even going with OE.

try the police pads, they are more aggressive, someone already posted the part numbers on the forum.

 the OEM rotors are far superior to the centric stuff. they are specially treated and have a hardness layer deeper than the aftermarket can produce. i believe GM treats the rotors for 8 hour in a special furnace for xtra deep harndess penetration, Chinese rotors are no match to OE

Am I missing something?

 

I was under the impression that the police version rotors were at least an inch wider diameter than "civilian" models..

you could be right, i'll try and find the part numbers someone posted up, but they have a varying pad selection for agressive friction compounds

 

I really want to modify the proportioning valve as this is really holding back on the trucks breaking distances, they are just using the front brakes too much and its not balanced.

 

if your not bothered by noise and dust , the Green EBC pads are fade free and extremely grippy

also to note the police SUV utillizes a 17" steel rim , i'm not aware of Police SUV's running 20" or 18" wheels

I tried NAPA Adaptive One pads on my 2015 Silverado Z71 and they put out a lot of dust on my wheels. I took them back to NAPA.  I now have Akebono Proact ceramic pads. No dust, quiet, smooth. Akebono is an oem GM supplier made in the USA. The Adaptive Ones were made in China.  (The Adaptive Ones on my Buick Lucerne have not had a dust issue)

My front rotors warped at 28,000 miles, dealership turned them under warranty and it helped the shaking till 38,000 and I was out of warranty. I replaced the front rotors and pads at 45,000 with the Powerstop z36 drilled And slotted rotors with their ceramic pads. No dust! No fade! Best upgrade I've ever did! $204 for the entire kit! Well worth it! I've not touched the back and I'm at 62,000 miles. When changing the pads, make sure to use the high temp brake lube on all the moving parts (pins, metal pad slides, etc). Also, inspect the rubber boots that cover the pins and if they are damaged, replace them. They come in a brake hardware kit you can get at any parts store.

Never needed pads on my GMT800 2005 Tahoe either. 200k. Factory brakes. No pulsing, nothing. Pads still had half thickness!

On my K2s?

Make a long brake on an off-ramp in the rain and you can expect a warp.

Metallurgy. That's what it is.

    • Maybe, but it seems he is the only one that has backed up data to prove what he is stating. I think he is doing this more because he enjoys it and wants to get the information out to us. He's got the knowledge and access to the proper equipment and having the funds doesn't hurt.  I would love to do what he is doing and would do it if and when I hit the Powerball.  I'm not a Tribologist by any means but love to learn what I can.   I would bet there would be doubting people out there if a completely independent lab with high quality work and highly respected in the automotive industry, put out information like this.  The world can't be pleased, one just has to take the information that they are given, do more of their own research to find actual lab data to back up what they are trying to figure/find out.  Most don't bother, they just want to believe what they first see.     I don't have the minimax but my 6.2 in my 2019 Silverado with 64k miles shows excellent UOA results with 0w-20 and for my own purposes 5w-20.  Since not much of a change using 5w. I liked the data sheet information on the SS 5w-20 and figured I would give it a try.  Still the same viscosity at 100℃.   In the end we all just do what makes us happy, life is too short to get upset over trivial social media.   On a side note, I do feel GM has dropped the ball and just cares about the bottom dollar and not quality anymore.  "Like a Rock" has been long gone.  Seems "Built Ford Tough" has as well.
    • Better than stock but that's like putting lipstick on a pig
    • Hello, my 3 month old Sierra Elevation wont recognize a trailer with electric brakes? All the lights work correctly, but no power to the brakes?   This is the factory installed brake controller. If you manually push the knob, the display shows the power % but does not light up like my 2022 silverado.   I have an appointment with the dealer, but was checking to see if anyone else has seen this issue.    Thanks, 
    • Been using SS 0w-20 from new, but wanted to change to the 5w-20 because I liked the data on the data sheet, to me it seems like a little better product. But as you can see, not much difference. This is also with running a mix of 10 gallons E85 to a tank topped with 93. It isn't a flex fuel vehicle so any higher I get a CEL for running lean on both banks. Yes my mileage takes a hit. Instead of 20 mpg I normally get on trips I get 17mpg. This is also using EaO17 filter.  What is amazing is I have the AMSOIL cone filter on it since I have the GM Performance intake installed and that air filter has 44k miles on it.  I just take it out and shop vac it off once a year.  I use the upholstery tool on my shop vac.  Works well.   
    • So, lot's of googling and reading, and a trial fit found, that indeed they hit the newer fatter caliper. I did some re-testing today, and found just 3/16" worth of washers was enough for the wheel to spin freely. I added 2 more on each, and again it spun freely. Tested lock to lock with the 4 washers, about 5/16" not quite the 3/8" Im considering, but pretty close. No issues. I've been looking at the BORA .375" spacers and using extended lugnuts to get back lost thread due to the spacer. All the ET lugs I've seen are all .33" reach inside the wheel lug holes. For those that don't like spacers or think they're unsafe, I think it depends on what type of spacers you're using and making sure you get good quality hubcentric ones, and if you're using bolt on ones, regular mainenance, checking the spacer lugs. Not wanting or needing that much spread. Looking for the minimum that will let me run these rims and tires.  it does look to stick out a little, but I really want put these on. and use the stock all-terrains in the winter.
