Hi. Last week I think I had a problem with my brakes. It was raining heavily, and I might have hit a puddle and hydroplaned a bit. At about that time I noticed that the brake pedal seemed to actually get higher. I am a two footed driver and my left foot usually is an eigth of an inch above the prake pedal. I believe the pedal came up and hit my foot. At that time I applied the brakes to slow down a bit and the pedal felt very high. I had no problem braking, and the system continues to work properly. Any idea if the pedal could actually rise a bit, and if so, what would cause it?

 

I also have a recall for the anti lock having an issue at slow speeds, but have not had any issues with it. I will get it in to the dealer for the recall when I have time (too busy lately).

 

Thanks

Couple years back my father had an issue with his 01 suburban anti-lock. The abs would kick in when it shouldn't have and would increase the amount of time it took to come to a complete stop. We almost had a couple of accidents. The problem was a sensor that kept getting dirty and screwing the abs computer. The dealership finally fixed it after 4 visits. They just up and replaced the sensors on the front end and did something (don't know what) to prortect them from getting dirty again. Hasn't had a problem since.

 

Hope this helps.

There was no stopping issue, actually the brake pedal was higher (and more solid?) than normal, I just have no clue what caused it.

 

 

 

 

I am just winging it now. Sounds like it could be a fluid issue. Could have an air bubble in the brake lines or a regulator out of whack. You may want to have a brake job done. That would be my guess, but I am not a mechanic.

      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.
