For those who did the dealer TSB street pads did the squeak completely stop?

if not i'm thinking of just keeping the pads I got due to the performance and eventually get the endless pads.

jafsport

very helpful links. Thank you.

yup, completely gone. but if you want to keep the original for performance, and the sound bothers you, you can just drive with the windows up and speakers loud lol.

Lol def love the sound of the car. ive had many V8s in the past including my favorites e92 M3 and S550 mustang GT and RCF is def up there.

Sorry for this newb question but what's a tsb? My service consultant keeps telling me that it's normal but there's no way s 24/7 squealing brake is normal. Thanks!

What people think is brake dust that is sticking to their rims on the RC F is actually mostly rotor dust. The stock pads wear slower than the rotors do based on volume.

Since everyone states that the MX72 pads wear out faster than the stock pads one can safely assume the pads are not wearing the rotors as bad and that's likely why the appearance of dust is minimal. Iron likely sticks better than the pad material.

There are even products made specifically to remove iron from your paint for detailing. CQuartz has a product called Iron-X that is used before applying their ceramic coating.

As you say, you can't defeat the laws of physics. So which is better? Rotors wearing faster or pads wearing faster? Can you prove it one way or the other with physics? Would you rather take the word of people that have tracked their cars using both pads?

I frequently speed over the century mark and have hit the speed limiter more time than I can count. I have noticed very little difference between the pads. Certainly not enough difference to matter to anyone that doesn't track their car. Those that do track their car will probably want track pads (and rotors) anyway, not dual purpose pads on stock rotors.

The MX72 pads seem to feel just a little softer while braking. But they still stop the car and the fade doesn't feel any worse than the stock pads.

TSB = Technical Service Bulletin / basically an email from corporate stating that if owners complain about ____, remedy the situation with ____.


I have the replacement TSB pads and the squeak is no more. The most noticeable difference with the TSB pads is initial bite. That's how it goes though, want less dust and no squeal? you get less initial bite and less stopping power at high speeds. It's a give and take.

Are the brakes worth it though? brand new this car is almost $80k and for that price I be hesitant to put some random Toyota pads on it. Thoughts?

Ken34

i mean they're OEM Pads that Lexus charges $1200 dollars for, while you lose the initial bite you had with the original pads, its not like they are crap for daily driving. it seems like losing the performance concerns you, if that is the case, just live with the squeal. you dont have to do the TSB, there is no safety risks to sticking with the original pads, personally for me, i just grew up driving never liking to hear that sound every time i brake in a car, so for me personally, it was like, i might as well do it, fresh brand new pads for free on our cars, ill take it lol.

jafsport

true! So this tsb is valid for the 2015 rcf? It would suck if its no longer covered on the 1st gen.

car has 26k miles

Ken34

mine is a 2015, had it done last week.

jafsport

thank you sir i will get it done this weekend. Did they give you a loaner car? Or was it quick hr?

Ken34

got a free loaner, they had to overnight ship my pads since they didnt have it in stock.

jafsport

Sweet I will take care of it this weekend. Thanks.

The tsb pads are still brembo pads, definitely not run of the mill pads they are just not as aggressive of a compound. Under normal driving conditions you won’t notice much difference after a few days, excluding the initial bite. Good luck
