Strange drum brake noise

Ok so, i recently had my rear brakes serviced by Les Schwab (maybe my first mistake lol)

After a couple hundred miles i now get this strange sound coming from my rear driver side drums. Midas mechanic listenes and said it sounds just like some parts are moving inside the drum and its "nothing i should be concerned about".

But i have ocd/anxiety issues i guess. Ive been driving nothing but tacomas for the past decade and this is never a sound ive heard before.

Has anyone heard this before? Could air in the brake line be causing one side to not fully compress and the noise im hearing be one side slowly grabbing?

The truck doesnt pull to one side when using the brakes, no noises when im stopping. Only this sound when im stopped and pushing the pedal.

 

Take the wheels and drums off and inspect the side that is NOT making noise and compare the assembly to the side that IS making noise, take a pic with your phone. Improper assembly could be one cause, over or under adjustment could be the other cause.
And this, DON'T step on the brake pedal while the drums are OFF or you'll be replacing wheel cylinders too.

 

I have a couple guesses.

1. They re used your old springs and they're noisy.

2. They didn't lube the proper spots and you have metal rubbing on metal without any lube

Only way to know for sure is tear down and inspect. I'd be happy to help

 

I live at an apartment complex that is not very maintenance friendly lol

Furthermore id be using my bottle jack + factory tire iron.




So, did that, took some pics, while putting the wheel back on i fucked up...

 

In other news... Noisey side drum slid* right off when the quiet side drum required slightly more effort to yank off (both came off without tools). So maybe the driver side (noisey side) was a little out of adjustment.

Didnt check all the grease points b/c im dumb.

Obviously now i have bigger problems lol

Looks like im out MORE money getting the wheel stud replaced.

 

When you do adjust the rear brakes.

Tighten the adjusters until the wheel locks up.
Then back it off 15 clicks.

Do this for both sides.

 

For future reference, this is a good practice for re-installing wheels:

1. In criss-cross pattern, tighten all lugs until the non-torque wrench (breaker bar or ratchet) gently stops on its own, or light-duty impact driver makes 1-click.
2. In criss-cross pattern, torque the lugs to 1/2 their torque spec, so torque to 42 or 43 ft-lbs.
3. In criss-cross pattern, torque the lugs to 85 ft-lbs. Repeat torqueing to 85 ft-lbs.

This guarantees that the wheel (or rotor) won't bind against the hub (potentially giving a false misread of the torque), and uniformly applies the preload between the lug nuts, wheel, rotor and hub.

I believe that Toyota is usually nice enough to allow rear-side access for tapping out the studs from the front, without removing the hub assembly.

 

Appreciate the advice fellas, it appears that replacing a lug stud is very straight forward. Gunna give it a go after work today.

Will be using a tourqe wrench to put the wheel back on this time lol

 

Update: stud replaced (well that was easy)

Gotta take the truck to the stealership to have a 2nd key made (i know i know)

Gunna see what theyd charge to adjust the drums. Hopefully have them replace my sloppy carrier bearing and front needle bearing.

With my whopping 1" lift theyll probably tell me to get fucked lol

 

I though the adjuster only rotated one way

 

There is a thing piece of metal that rests on the adjuster to keep it from loosening up on itself.

Lets say you overtighten your brakes, You need to use a 2nd tool to push the metal piece away from the star wheel to loosen it back up. Sometimes, it can be a major PITA when youre using screw drivers and flashlights. Sometimes... you can even get impatient and decide to just rip the drum off to make it easier, usually resulting in damage to the brake hardware.

 

"Sometimes" lol

 

Was not a good day. Pulling mt drum off and having pieces of hardware fall onto the pavement. I was very bummed.

I gotta learn the hard way i guess. I can build guns, computers, houses but for some reason i botch everything i do to my truck lol

 

What components did they replace, if any? Shoes, drums, hardware? New drums take some time to "season", if that is what you want to call it. Lesser-quality brake shoes can create noise too.

 

You posted as I typed... If parts are falling out when you remove the drums then there is a problem. Even if the shoes are tight, you should not be dropping-out parts when you pull the drums. What fell out?

 

Parts falling out was a few weeks ago, they have since been rebuilt (and now are making this noise). Only ~300 miles on them since the rebuild. The shoes were so tight i pulled half the assembly apart* with the drum when i had overtightened them. The retaining springs? Fell out when that happened*


Les Schwab did the rear rebuild about two weeks ago, im sure the shoes arnt the best quality. They replaced shoes, hardware, cylinders and machines the drums. I was desperate after ripping them apart myself i just went to the nearest shop lol

Again, that catastrophe was prior to the rebuild.

 

Sorry man I have been there, we all have. Take your time and remember it's ALL repairable. This site is an amazing resource, as is youtube...When things brake bad step away and come back to the job in a few minutes. Great thing about brakes is there is a mirror image on the other side, use that to your advantage putting things back together. Google image helps too.

 

No, it will go both ways.

 

Well, local dealership said $75 for a brake adjustment, which would include cleaning and fresh grease.

So, while i know everyone will laugh at the idea/cost of that. I think imma give it a go to settle my anxiety/ocd


Plus i need a spare key made... which of course the tech gave me the old "well, sometimes those Amazon keys wont work when we try to program it"

I bet i regret this lol

 

Skipped the dealership, took it back to les schwab to have them adjust any slack or w/e.

Dude said the drums seems fine, pulled them apart, checked drag, all seems well.

He said its the leaf pack binding/unbinding... Which i dont see how that could be a thing when the truck isnt even moving.

He said even when your sitting still, applying excessive pressure to the brakes and still cause that... Fml
