Brake Squeal in reverse?

[tsamsing]

Toyota now says that new calipers are needed. Of course the dealer only has one on hand (like the actuator) so they have to order another and have it shipped. The saga continues.

100% Correct on all points. On the good news front, post 10k mile service and 2nd oil change I averaged 24.5mpg with cruise set on 75 on a 400 mile trip.

Tailwind, right?

I'm coming up on 1,000 miles, but am still getting a significant amount of brake squeal baking down my driveway in reverse each morning. Is this normal?

NOT normal, mine too! Started at 1500 miles, at dealer now- they tried to convince me this is normal; but I won't accept that- I don't care, replace the rotor, pads, everything..... unacceptable for a brand new vehicle....

I just talked to my service rep again. She followed up with Toyota and they still have not released a service recommendation. The service manager admitted Toyota knows it’s a problem after I showed him that Lexus is already put out a service bulletin to install a shim kit.

Maybe someone could have one of the bigger Twitter influencers to post some videos of this. The sound is horrifying. Toyota would not like that posted online about a new model.

After having my LC for a month and greasing the brakes and installing new calipers the problem persists albeit not as bad for now anyways.

Has anyone read the Lexus TSB on what they do to fix it in a Lexus GX550?

Attached. I think there's an updated Rev 1 to add 2025 MY, not sure is anything else changed.
