Cruise Control & Brake Pedal

Hi All,

Lately I've been experiencing problems while driving on cruise. Sometimes cruise works, sometimes it doesn't. If I tap the brake or smack the side of the brake with my foot then it seems to work. However, it is getting worse. Now regularly I have to do that and sometime it still doesn't work.

There is a little slack in my brake pedal as when I put my foot under the brake and lift up it does move a bit. However if I lift it up and attempt to apply cruise it does not take into effect. Has anyone experienced such problems? What would be your suggestions? From what I read it is not the easiest task to replace a pedal? (if in fact that is what it is)

Thanks in advance,
vanspek

Sounds like a bad switch on your brake petal. Not sure if the cruise uses the same switch as the brake lights, but you should be able to crawl under the dash and see if there is 1 or 2 switches that the petal is hitting.

The cruise cancels on a brake petal push, so it could be a bad switch, or you just need to adjust it so the petal isn't bouncing into it.

my 07 silverado does the same thing. separate switches i think. on mine, brake lights are separate from cruise and trailer brake controller. lights work fine, cruise and brake controller act up.

I recently had this issue on my truck. Mine was the cruise wouldn't kick in sometimes but also my remote starter wouldn't shut my vehicle off.
So I crawled under my dash and noticed 1 white wire that is attached to a connector on the brake pedal hanging out. I pushed the wire back into the pin and squeezed on it with needle nose pliers to get it to stay in there.
No more problems for me :lol:

My free fix - priceless
Dealer fix - Who cares when you can do it yourself!

There was a same problem with mine '07 truck. I have repaired it as follows: removed the brake lamps switch, disassembled it and turned in contacts.
If you don't want repair brake switch, you can get the new switch. Part # 25981009

Amen brother. I had the same issue on the 08 to include brake lights turning off even when the pedal was pressed. New switch and done. I don't even think I needed a tool.

      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.
