2014 Taco Rear Brake Squeal

I've noticed this same thing recently on my 14' when I am driving with the radio off. My truck only has about 6200 miles on it so nothing should be worn out already! Like you said OP I only hear it when coming to a stop. I hear the squeal literally only when stopping between 10 mph and 0 mph. I am interested to see what you find out if you take it into the dealer. I am not really worried about it right now since my brakes feel fine and it is a very faint noise. If you find something else out tho I might change my mind.

 

I have the SBS (school buss squeak).

Maybe it's from build up on the shoes or the drums need to be re-surfaced. Either way it's annoying...

Definitely the rear brakes. The car sat outside for a few hours and when I pulled into the garage, it really made a racket while feathering the brakes pulling in slowly.

My son said it was the passenger rear. In the garage with the windows down, it was very pronounced. Not a high piercing squeal, but a noise that shouldn't be.

I've Googled the problem and can't find information about this issue w/2014. The 2011-2012 yes, and the symptoms are identical.

 

you might try the good old trick of a couple of stops from reverse and see if that helps. Drums have slack adjusters that work when the brakes are applied in reverse. It also helps to scuff off any little debris that might be contacting the drum unevenly and causeing noise. Its also easy and free to try.

 

I have the same issue on my 2011. The dealer argued and said it wasnt covered under warranty. Now my truck is out of warranty. So I'm just going to replace the shoes and drums myself. I dont want those morons touching my truck anyway.

 

Did you take it in when you still had warranty?

 

My 2013 has squealed from day one in reverse. Only in high humidity. Dealer can't hear it so its not a problem to them.

 

I have a 2014 with 4100 miles and I have noticed a squeak at low speeds. It has only been in the colder weather.

I figured it to be the seals on the shocks. <-- Thought nothing concerning further than that.

 

What a shitty, dickhead post. Nice job, Ace.

 

Yes and they wanted to argue with me and tell me they would charge me if it was due to brake wear. I'm not giving anyone my business that wants to argue with me. It's annoying but I'll just deal until I get new brakes. they arent that expensive and I'll put them on myself.

 

Have been noticing the same faint sqeal at low speeds on my '13, usually pulling out of the garage in the morning...called my dealer, said there have been some issues with brake shoe dust, and dirt/salt causing the prob....taking care of it under warranty, when it gets above freezing.

 

Questions I have are..........

Do we KNOW what the root cause of this rear squeal, especially on newer low mile units?

Is there a TSB out there on the topic?

Does the TSB offer a solution under warranty?

Is braking actually affected, or is it just annoying?

Or is there just a lot of complaining in here, and no one really knows what's up?

All that said, I hear it on my '13 10k unit sometimes too. More of a moan than a squeal to me.

 

That sucks. All I did was tell my toyota adviser and he pulled up a TSB (2011-2012) to fix it. I heard if you take it in during your warranty period and they have it in the system, you can possibly still get it?

 

I have an appointment this Saturday. Based on my over-the-phone explanation, the service technician said the first thing they'll do is check/adjust the parking brake tension.

A friend was in the truck today, he described it as a harmonic vibration, similar to running a wet finger around glass rim. It made sense. The noise is identical when it occurs and it is hard to reproduce. It may do it several times a day - or not.

It's when I get to that sweet, or shall I say, squeak, spot with speed and pressure on the peddle.

While mine is a 14, the TSB above describes the issue perfectly.

 

Rear drum brakes have been around since the dawn of vehicles. It was posted already. Drive around, get brakes warm. Then find a good spot. In a straight line in reverse, get it up to around 20 mph and brake. Not hard but feathered. Do this a few times. You will see improvements each time.

Going forward the braking bias is about 80/20 front to rear. In reverse you go to about 60/40.

The brake shoes are glazed. Going in reverse cooks off the glazing.

My Opinion.

 

The service tech explained it as typical for someone who breaks lightly as I demonstrated it at a crawling pace of maybe 1-2 MPH. He said quite a few Toyota's do it, including the Camry.

He suggested I brake harder once and a while, including in reverse, to keep drum glaze to a minimum.

Mine is not a squeal but more of a harmonic resonation; akin to running a finger around the rim of a thin walled glass.

 

I would say that describes the sound perfectly/\ /\

 

Here is something I did on my '09 (currently at 59k), and all the drum brake cars I have owned if they acted up like yours are.

Mark your drum and one wheel stud with a mark to index them...Sharpie or dot of some kind. Remove the drum; on the Tacoma's there is a paper gasket on the axle flange to help with corrosion/harmonics. Take compressed air and blow all the dust out that you can (don't forget a dust mask and safety glasses), then take some 180/220 grit sandpaper and just brake the sharp edge on the shoe material at the top, the 90 degree corners, and the outer edge/long side that faces the outer part of the drum. Nothing too aggressive, just brake the edges. Then finally, take a fresh piece of sandpaper and just scuff the friction surface...the part that rubs the drum brake surface, and the drum friction surface. Again, nothing dramatic, just brake the glaze on the friction surfaces. Blow everything out real good (don't forget a dust mask and safety glasses), put your drums and wheels back on and drive a little while and do the backup and step on your brakes several times to let the self adjusters do their thing. Sometimes when they self adjust they seem a little tight and glaze up a little.

Not foolproof but tends to quiet them down. Modern friction material is different than what was available in the 70's, 80's and 90's and can be temperamental sometimes. Good luck.
