Have been told nothing can be done about squeeky brakes on our 2015 GS. No squeeky brakes for first 15,000 miles. Service manager says "they will just have to get used to it" Can't accept that answer. Anyone else having the problem?

Brake service or cleaning should work. Can you describe the squeak? How does it happen, at low speed? high?

Anyone get a lot of brake dust?
I get a lot on front, but nothing in the back?
What gives?

Squeeks first time we put on the brakes after car has sat for four hours or more. First intersection, squeeks. Then does not squeek until car has sat for a while. Just had car serviced, tires rotated, brakes checked. Said they blew out the brakes given chance of summer dust and dirt. Didn't work. Several have mentioned going to a brake shop or tire store such as American Tire. Am working with Lexus Enform and have been assigned a case manager. Am waiting to hear from him as to next steps.

Yes, lots of brake dust, but only in the front. I have stock pads on 2015 F-Sport, 38K miles. No squeaks at all.

This is similar to what my car does, 2015 F-sport AWD, 17K on the clock. Sometimes it doesn't fit that precise pattern though. Like for example I put the car in the Garage last night after driving 50 or so miles then getting home at 1 AM. took it out at 9AM this morning, ZERO brake squeal when leaving the house..... But I bet there's about an 80% chance that I'll get a huge dose of squeal on leaving the parking lot at work today.

If you read the other thread there is a Lexus BRAKE SHIM part that probably needs to be installed. I'm not that annoyed by it so honestly I'm not even going to bother getting that looked at until I go for my next oil change.

Most cars with 4 wheel disc, the brakes are "biased" such that more braking force is applied in the front of the car than the rear because of the weight distribution of the car... not to mention, if you look at your rotors, the fronts are probably significantly larger than the rears, so there's more surface area going on there.... so likely more friction up front = more brake dust gets generated because the fronts do most of the work.

I get brake dust on all 4 wheels but its not that difficult to clean off the polished part of the wheel. I just scrub them with my car wash brush, hose them off with the pressure washer, and if still dirty ill use some rags to wipe that crud off with some kind of cleaner like Spray 9. The real pain is in the recessed area actually inside the wheel, except it is much more difficult to notice this because of the lip separating the two parts of the inner and outer wheel.

It also helps that my wheels are Gray/gunmetal colored instead of like silver or something. If you have lighter colored rims the dust is going to be more apparent. (this is part of the reason why I didn't get a car with silver rims, LOL).
