2014 Brake Creaking

I've searched and can't find the answer.  I have a 2014 Silverado 5.3 with 50k miles and just started noticing a loud creaking coming from the rear driver side brake.  it happens when I'm at very slow speeds or even when I'm stopped (so I can't see how it would be something with the rotor etc). I've found threads about similar issues and have tried all the suggested solutions without success (clean caliper, parking drum, rotate piston, clean guide pins, etc).  I noticed it is much louder and more regular with the engine running as seen in the video.  Any ideas?  Thank you in advance.

I had the same issue but it was always a sticking caliper pin. Replaced my calipers pads and rotors. All is good now.

Stupid question, but how do you know it was a sticking slide pin if you changed rotors and pads? How do you know it wasn't the pads? My 2017 with 40k makes this exact same noise and other threads I've seen say its the caliper piston on the pads. And to either regressed the backside of the pads or put on new pads.

I cleaned the slides twice and the problem went away. Then I finally just replaced everything because the problem kept coming back. I was upgrading the brakes too. Fleet pads, slotted rotors and new calipers front and rear. It was definitely a sticking slide pin causing my noise though.

I can suggest something else for you. I had this issue on my 2014 as well when I changed the pads. If you have pads with a metal backing plate that sits in between the main thick metal backer of the brake pad and where it is clamped on by the caliper you may have some rust inside of there or just the metal rubbing.

 

My slide pins are lubed up with silicone and the pistons move like brand new. I also bleed my brake fluid and vacuum it out every year just to try and prevent my lines from rotting out from the inside out.

 

What I would do is get a helper and have them press the brake down and go to each wheel and listen to see which one is making the creaking noise. In my case it was the rear brake pads on both my silverado and my old envoy that did this. I had plenty of pad life on the pads for both of them but what I did was use a small flathead screwdriver to pry the little piece of metal that is riveted on the thick metal backing place of the pad and squirt some high temp brake slide pin lube in there and use the included bottle brush to shove the lube in the middle as best as I could. I then squeezed the backing plate against the thick metal backer and wiped the excess lube off of the back of the pad. Then I put some high temp brake lube on the piston(s) and the mounting ears that come into contact with the brake pads and bolt everything back up.

 

If you want a great quality brake lube for the pads, I use Permetex Ceramic Extreme and for the slide pins I use Napa sil-glyde. ONLY use silicone lube on the slide pins though. Any other lube will cause the rubber to expand and lock up your slide pins (trust me, I had that happen on my old truck lol)

 

edit: You are also noticing the noise more when the engine is running because you have way more pressure being applied to the caliper/pads than if you ran out of vacuum assist and the engine was off and you tried to slam the brake pedal down. Mine would squeak at about halfway through depressing the brake pedal and continue until I maxed it out.

Thanks for all the replies. I had tried everything (including the parking brake and slide pins) and nothing worked.  I broke down and tried kickass' idea and bought new pads.  I drove around for 30 minutes today and so far no noise.  I don't want to jinx it, but I'm thinking it may have been the rust between the back of the pad and the metal plate.  Thanks again!

      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.
