Driver's side rear brake noise

This started after I replaced my rear brake wheel cylinders. I used new Toyota OEM Those sumbitches are so much heavier duty than any other wheel cylinders I remember rebuilding in passenger cars years ago

for what it's worth replacing these wheel cylinders and properly bleeding the brakes including LSPV corrected the mushy feel I had on the brake pedal. I had previously let the shop put the new Power Stop heavy duty for towing calipers, rotors, pads, and brake shoes on. Also a full brake fluid flush

And I had a good road test when I went on a trip with three adult friends a few hundred miles away A ladder fell off of a truck in front of the 18 wheeler in front of me and I hit to hit them hard and was very pleased. That's the first I've really had to get on them that hard since I put the new 305/32s so I was expecting worse performance and was going to do the Lexus brake upgrade in the future. I'll still probably do the upgrade, but I'm satisfied for now

anyway, now I've got this squeak at slow speeds only on the driver side

also, it doesn't do it consistently, but it does do it over half the time

 

I hear a rhythmic creak, is that what you're talking about?

 

Yes, I should've found a better example of it but a rhythmic creak that happens most but not all of the time as you're flowing down below about 15 miles an hour

 

Is it the driveline rubbing the carrier bearing

 

I have a similair creak, but not rhythmic, it happens when releasing the e-brake, that similar creak/groan noise. I never thought about what it could be, but I've experience that in virtually every truck I've ever owned or driven with drums since my very first truck, an early 80s GMC S15 4cyl/manual damn near 40 years ago now. I just chalked it up to the springs bucking or similar.

 

This is normally much louder than what is in the video. I just happened to catch it when I was making the video for the potential axle wrap issue. Loud enough to be very annoying
