I thought this too, and checked again. Yes I dialed the right number.
Brakes SQUEAL while backing
- Thread starter owtlaw
- Start date
Actually I'm in the right place I guess. I just thought differently because when I put the number in my phone, it says Toyota Battery Manufacturing. Lol
I have had mine LC since April and was having the same issue with brakes - but on one of the threads a gentleman discusses doing the stops repeatedly to bed the brakes (I believe that is the term he used). But he gives very specific instructions on how to do this. The first time, I just hit the brakes hard a few times at low speeds probably a half dozen times to see if it would have any effect. It actually did fix the squeal but only for a week or so. But, i remembered he suggested that you do it repeatedly until you smell the burn inside the vehicle - and then drive for several miles to allow the brakes to cool off. This past weekend I set the brakes repeatedly over about a 5 - 6 mile drive as I happened to be out early and didn't have any traffic around me in our rural area. I never actually smelled the brakes but I got them hot enough that I could see smoke coming off the front brakes. I couldn't tell about the rear. Then I drove the vehicle for probably 15 miles or so total. It hasn't been a week yet, so I can't say how long it will work. But I have not heard the squeal yet, and I will say the brakes seem to be gripping better and stopping better than they were before. I wish I understood this concept a little better but apparently it is wearing off some protective?? layer on the brakes? Maybe someone with some technical expertise can explain that -
IMO it's the pads having an even wear in relation to the surface plane of the rotor and the amount of "bleed-off" of the caliper piston(s) which would allow more distance between the pads and rotor. On many different models the pads have a stainless steel spring which assists the pads in separating and "bleed-off" of the caliper piston(s).
Again IMO, if there were pads that had the locating holes in edge of the pad's backing plate (where the spring hooks into), that would retrofit into the LC's calipers (along with the spring), it would permanently fix the squealing issue.
This happened to me several months ago, when my girl friend and I visited Brasstown Bald, the highest peak in Georgia. Coming down from the parking lot, i tried using engine braking to slow down, but it didn’t work. Miss Daisy’s brakes were stinking like crazy. They were quiet for about a week after that. But they started squealing soon thereafter.
My local dealer still couldn’t do anything for me at my 15K service. My neighbors have been giving me that look—you know, the one you get when your brakes squeal like a dying pig. Not wanting to wait for the TSB, I ended up ordering a new set of pads: PowerStop Carbon Fiber Ceramic #Z23-2442 for $55. Dropped them in today with a little Liqui Moly Brake Anti-Squeal Paste between the pads and the shims. Squeal eliminated.
IMHO, I think the rotors feel a bit light (less dense), which might be contributing to the vibration-induced squeal. I’ll probably swap them out in the future for PowerStop slotted rotors, which I’ve had great success with in the past.

I figure it's Toyota's stealth back up alarm!!
Looks like Toyota has issued T-SB-0046-25 for the 6th Gen 4Runner and LC250 brake squeal issue.
Wait, what? No replacement rotors?
After replacement of my pads with performance aftermarket pads 1500 miles ago (I have used these pads for years on my 4Runner), it silenced the reverse squeal, but now I hear a drone sound when coming to a forward stop, which tells me these rotors have issues as well.

I wonder how much TRD John’s Land Cruiser Forum takes away from our forum?
I completely overlooked that he runs his own lc forum. I assumed he meant this one. pretty interesting.
Toyota has a TSB for this now, mine is at Toyota now getting the new parts installed.
Same issue here. Have to back in garage every night so as not to wake up neighborhood at 4:00am when leaving for work
I am taking mine in tomorrow for the TSB service. I expect that will fix the problem.
My dealership seems to have fixed the problem after ordering/installing TSB parts with a 4 day wait for parts.
Your dealer shouldn't have any objection to applying the TSB for you.
Took my LC in at 8am and by 1030am it was completed yesterday. All seems to be well now. Based on the description of the work order on the receipt, they performed the TSB per the manufacturer's instructions. The next time it rains will be the true test of whether it is fixed or not. That's when it made the worst squeal when backing up.
Fear not… it’s fixed..
Brake squeal fixed. Parts ordered in August and installed one week ago. No more squeal. So pleasant now…..
