While not an inexpensive repair for you although far less than what prices I see up here, still the fact comes down to a very low mileage truck and in my mind all the parts should have lasted far longer. The park brake shoes fell to pieces on a truck that has in your hands seen little winter roads and you found nothing wrong with the slide pins to account for the uneven wear but the caliper itself was an issue. My only question is, will the other caliper become an issue at some point or if its a rare issue. 

 

I've not used powerstop brake parts myself because the supplier I tend to have bought parts from has been a lot more into Raybestos parts so I get what is available pretty much. The weird thing about this particular local chain stores website is that they don't show much for options pad or rotor wise on the 2025 model but if I go back to a 2022 model then Powerstop parts show up and some other even cheaper ( I suspect real econo hokey parts then ). As far as I had thought most the brake parts were the same from 2020 up, maybe they are just hiding some options to force higher priced items. However only the GM park brake shoes show up. Oh and as to the park brake actuator, for the GM unit which is all they list they want 750.00 for one of those. I see on Rock Auto that one can buy the whole cast bolt on axle mounted brake housing with the actuator and comes loaded with the park brake shoes for a fraction of that if one wants the whole assembly, crazy. 

Wish I could answer your questions... I hope the new caliper is not an issue and hope the rest of the calipers are good. Only time will tell. 

 

I have used Powerstop on other vehicles, I have not had any issues. The pads/rotor/sensor package is only $300 USD for the rear. I am not sure where I got $400, maybe shipping. The kit is listed for 2020-2024. Same kit for gas or diesel. Nothing listed for Powerstop in 2025-2026 models.

 

RA does have the rebuild kit for $18 USD and multiple options for the shoes. GM shoes are listed for $67 USD and fit from 2020-2026. I had to get the parking brake shoes and rebuild kit locally, as I didn't know there was an issue until I pulled the rotor off and the lining fell out.

The truck will give you the answers all right as time goes on, they always do !. 

 

Good to know about your past experience with the powerstop brand brake parts. I sort of suspected that about your surprise findings when you pulled the rear rotors and already having the parts you assumed you would need on hand, not expecting to dream that your park brake shoes would be in anything but perfect shape and I would have assumed the same thing based on the type of use and low mileage. Going forward from here you will see what they look like the next time you pull a rotor for any reason and see what you find. 

 

So at this local parts supplier they list the OE GM rear rotor at 410.00 ( per rotor ) , the OE GM brake pad kit at 413.00 , the park brake shoes and looks like a per side set only and is 196.00, the spring kit per side is 45.00 and the adjuster is 16.00. So if all OEM parts were used and in theory this is slightly better pricing than the dealer, it would come out to 1750.00 to do rotors and pads and the park brake shoes. This being in Canadian dollars so about 2/3 of that if converted to USD. Also keep in mind with driving a vehicle in the winter here its very likely that given a few years the calipers are garbage in one way or another, either rusted up not working properly or the bleed screw if touched twists off as they get rusted in solid. The way they word the calipers they say new so who knows but they are 228.00 a piece plus a 53.00 refundable core charge and surprised they are not more to be honest. But that gives you an idea of what one is looking at up here for an OEM brake job for the rear.

Chuck do you have a carquest out there, we just did our 3500 with premium parts from carquest and they were a lot cheaper than napa  and of course the stealership.carquest also had all the parts for the parking brake

That is a good question as I have heard of the company but knew we had nothing local so I went to the official website and they show currently that there are no locations anywhere west of Ontario. Yet some non company information websites claim a few locations in Alberta but perhaps they closed or its bogus information. The two main parts suppliers around here is Napa and Pats Auto. There used to be some others, Bumper to Bumper and so on but they all have vanished. If anyone is wondering what the heck is a Pats Auto, its a company that is local from the 1950's and grew into a few locations in this part of Alberta and BC. We are lacking competition it seems and with that they are pricing accordingly because they can. 

 

As to the prices I threw out, those were all acdelco parts and this confusing matter of not listing parts that I at least think fit a 2025 model going back to 2020. If I am correct then there are somewhat cheaper alternatives for some of the parts and then what to me sound like some real low line parts, but not listed for a 2025 model. Napa shows no park brake parts even if I go back a few model years which is odd but they have their house brand brake pad set for 140.00 which sure sounds good after looking at the delco prices although I have no prior experience with Napa branded brake parts.

lordco is expanding in alberta, slowly

partsource is basically the same as canadiantire, but just their parts department

napacanada is (I find) expensive and has a poor selection compared to napa in the us

partsking.ca ships, and sometimes has decent pricing, but doesn't have the brake parts for your truck, location in edmonton is convenient for pickup

I looked up the various companies you named off and of no surprise other than Canadian Tire or Napa, the closest locations are in Edmonton which is 500 km away and why it would seldom make sense to go there for parts. Never the less interesting to look through the various websites and certainly some of the same parts such as Raybestos etc sold through Lordco are cheaper than what Pats up here sells them for and part of that would be the shipping costs to get anything up here but also the fewer competitors the more they can charge. I may have missed it but I did not see any park brake shoes listed through any of them, after all its not supposed to be a high wear item other than this rust issue that Newdude said is all too common in the rust belt. 

 

Speaking of Napa and I don't know if any of you reading this have ever watched any of the youtube channel from a guy in Alaska called "Truck House Life" but with his various older Ford trucks with the 7.3, its almost a running gag of him driving across the lower 48 or up through Canada and in Alaska from one Napa store to the next to keep repairing his trucks. He claims he doesn't have a partnership with them but then he is sure giving them some free advertising !

When I raised this with the dealership, I wasn’t told it was “normal” or that something had failed. Instead, I was told this wear pattern is “very common on all the new trucks,” with traction control and Auto 4WD cited as possible contributors — and that this is simply something owners should expect going forward.

That response is unacceptable.

 

Common, yes. Normal, no. Either a slide is sticking or a piston is.

      Oil Consumption

      By Chuck FB · Posted

      So speaking of oil consumption with my L8T as I just changed the oil yesterday and made the switch over to Amsoil SS 0W-40 from the Mobil 1  5W-30 Truck and SUV I just dropped out. 2900 miles on that oil as well as  68 hours on that oil ( so used to equipment with an hour meter and that becomes valuable information to compare with others as well ). Once again the oil use was so very little, I am going to say it dropped under 1/16 of an inch on the dipstick. No towing was done and this interval was from early spring until now.    One interesting item to note is that going by the 5 quart jugs I was using before from Mobil, it was showing that I was putting in 8 US quarts to bring it to full if not slightly over the full mark according to their jug markings. Granted I did allow more drain time this time and in part because the engine oil was only lukewarm as I started it and let it idle and not for long enough to get the oil itself hot ( the engine was up to operating temp ). The oil in that state just seemed to take forever for it to drip out but not only at the drain plug but at the oil filter housing as well, perhaps I had never quite gotten all the oil out before and I could have still waited longer but as it was I waited well over 3 hours. I think next time if I have the time I will do an experiment by dropping the oil and lets say leave the pan under it for 15 minutes, then switch to another pail and let it drip out overnight and measure how much more oil comes out. So this time and yes I ended up getting it just over the full mark as I was experimenting with trying to get the level to the add mark after I had run it and then waited some and then added a bit and waited for a certain amount of time for it to settle to the add mark. I very well may not have waited long enough for that experiment but I got to the add mark, then dumped in a full quart and waited some and checked and then waited some more and it crept up more ... and then finally oops, it was slightly over full some hours later when it really had settled all it would. I find this engine sure takes time for the last bit of oil that gets poured in to finally make its way into the crank case. I can only guess at how much too much I added as per maybe a 1/10th of a quart. I had poured in 8.5 quarts going by the quart containers as per 8 quarts and 16 us ounces. I was shocked at how much this was off compared to the prior oil changes and if those larger jugs and they are not marked accurately enough or they contain slightly more than what they say, or the drain time factor made that much of a difference. But I know on this forum there have been others who have said they have put well over 8 quarts in their L8T and now I have also going by the Amsoil true quart containers. Its a confusing convoluted mess up here in Canada with some oil manufactures packaging is in true US quarts, some is also in true US quarts containers on an even number of quarts but also marked in liters which becomes the odd ball volume of a fractional amount of liters. Then there is the Liters only containers, no US markings as its a true metric container and only measured in Liters to an even number of Liters. But remember we used to have Imperial Gallons and Imperial quarts as well !.

      Holy smokes. Clearly not a deal on that truck. I just mean in general, matte or painted trim is becoming more normative than chrome, but I know the Black Optics packages on various vehicles are being sold as uplevel trims. They look really good, but sheesh. It's just paint and plastic.

      Some Assembly is Required

      I Wouldn't Know Where to Begin    Oh I know where I would begin but I'm just one of over eight billion people on this rock. Eight billion versions of where the goal post is. How large it should be. How far to kick from. What ball is the right ball. Elevation. Age.....are you getting the point? It isn't about disagreeing with one individual. It's about agreeing only with one individual. One's self.   Agreement comes when multiple people hold the same point already. THAT is the goal of an education. Building the Social Contract. That thing that allows us to all read this sentence. We've agreed on the alphabet and how to arrange those letters into words we agree upon whose meanings hold true for everyone entering into that contract. Those words arranged into a sentence form an idea and several sentences strung together in a paragraph convey an argument for or against or inform the reader of a state, condition or perhaps reveal a things nature. Paint a word picture. Make oneself known.    This contract is not limited to words although they are often explained by words. Things like numbers and their usefulness. Physics, Chemistry, Medicine, Music, Art and so on.    The frequency of middle C (C4) is 261.63 Hz is a first principle. We build on that to make music we all can enjoy even if we all can not compose or play. You don't have to master it to make it enjoyable and useful.    So why is the Beginning so difficult? Why is agreement so elusive?   Everyone "Signs" the contract (when receiving that education in obtaining it)  but fewer and fewer in this world have any intention of living by that contract. They find exploiting that contract more advantageous. Disruption. With intent. Without intent. In Ignorance. In your face. With a double dog dare you. With a hold my beer. In resistance to that contract and in spite how it looks on us. It permeates the very air we breath.    In this way the contract is subject to advantage. Abide by it when it serves you, disregard it when it doesn't. Unpredictable and self-serving. Corrosive.....Toxic........   It says a lot about a persons character to disregard the contract, the truth, first principles. None of it good.        ********************************************************   https://medicine.yale.edu/news-article/character-vs-personality-who-we-are-and-who-we-aspire-to-be/   Just an interesting article.

      It costs $5,250 for the Yukon Nightfall option (black wheels, emblems and illuminated black GMC grill badge). What a "deal".
