This will probably be my 1st major mod, if the kits are available.

I had that same thought when I first bought my truck, but the drum brakes in the rear are perfectly fine 99% of the time.

I felt the same. Was pretty surprised that they are still throwing drums on these.

 

I would prefer disc because of the ease of maintenance personally. But not enough for the large investment of doing the conversion... if there is one available. One of those things I will "live with."

Drum brakes are hardly difficult to maintain; if anything discs on the rear of a truck are worse. I've heard of people having all kinds of problems with the rear brakes having issues with corrosion on rotors and in calipers that get stuck, whereas with drums since all the mechanical parts are enclosed by the drum those issues don't exist.

 

Either way, the front brakes do 70-80% of the work regardless which style is on the back.

That's true and the ratio will be the same whether disc or drums are used on the rear.

 

Now if I were going to improve my braking I believe I would start at the 70 to 80% end first.

 

Just my humble opinion.

When breaking the force should shift to the front. This is why the front brakes do most of the work and it helps the steering wheels maintain traction while braking. If you shift the braking balance to the rear then you will loose steering traction while braking.

No one is talking about changing the break bias, just like on a motorcycle, a car/truck's front breaks does the majority of the braking; I just like the looks of rotors and calipers as opposed to the drum.... and i'm pretty sure on a skid pad... there would be a slight braking improvement...

So are you saying you plan to drive your truck on a skid pad on a regular basis? :lol::lol:

This is the first truck I have owned with drum brakes, and I know nothing about them, sorry to go off topic.

 

How is the maintenance on drums compared to disc brakes? Do they last longer? What will it cost me to have them replaced or recut whatever has to be done when they wear out.

 

I already had the front brakes re-cut on my 09 with 11k miles on it under warranty because of noise and shutter.

The cost of drums is usually cheaper because the shoes usually last longer. The main issue with drums is if you go thru deep water or mud often. Those situations cause the drums to get contaminated and corrode more than usual. Also the main maintenance issue with drums is if they have been neglected long enough to creat a lip on the inner edge of the drum. That can often make it a royal pain to remove the drum. And don't be afraid to use the parking break regularly to keep everything free'd up. On some vehicle the rear brakes self adjust when you brake in reverse. Others self adjust when you apply the parking brake. Not sure how these GM drum brakes self adjust.

If you put some 50 dollar brake dust shields on, you cant see which type of brake you have. You are talking about spending a whole bunch of money for something to "look" better. You could do a whole bunch of other stuff with that money that would make a noteable improvement in your truck.

      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.
