autozero, can you define driving 'very spiritedly'? i'm amazed you're eating through pads/rotors. the LC does not have wimpy brakes, although if you're on a track yeah they're gonna get destroyed quickly (repeated high speed, heavy braking).

obviously the LC is no mclaren.

 

It's a 4500lb car --- any 4500lb car is going eat thru brakes if driven briskly especially if they're not performance oriented brakes. I consume thru tires just as fast for reference.

 

If you have to ask, you can't afford it. lol
Prices vs performance is always a personal decision.
If I tracked a car a lot, I would go with cheap.
If I was aggressive on the street, I would go ceramic.

 

ok i need some more info...

what year is your LC?
how many miles does it have on it?
how many times have you replaced pads?
how many times have you replaced rotors?
is your spirited driving on a track?

thanks!

 

Look at EBC yellows. I’m running them on my GSF and they are impressive. Much more initial bite than OEM which is important as brake distance is reduced. For the rotors, make sure you are bedding the pads in correctly. Also, the EBC pads have a pink “break in” coating which actually preps the rotor’s surface. You shouldn’t have to replace the rotor unless it is below the minimum thickness or if you have shudder or jitter which can be caused by pad imprinting.

For replacements I’d look into a different two piece replacement rotor that allows you to replace the outer ring if they get worn rather than the entire rotor. This is a less expensive solution.

Here's a photo of the hotspotting on the rotors. My tire guy confirmed, that turning or resurfacing the rotors wouldn't solve that he and said I'll probably have to replace rotors each time if I stay with steel rotors :/

 

What exactly causes hot spotting? My former Lexus service manager said it was caused by moisture trapped between rotor and brake pad, and allowed to stay there for a period of time. This thread suggests it’s caused by aggressive, spirited driving, leading to rotor overheating. Can anyone help? I have an LS460 and a new-to-me LC500. The LS has gone through any number of rotors — and it is never driven hard.

 

Here's EBC's description on hotspotting:

https://ebcbrakes.com/race-motorspor...ses-and-cures/

After reading it, I still don't really understand what exactly causes if because I've owned 11 different cars and the LC is the only one that I've had issues with (though arguably an issue worth dealing with)

 

My last 3 cars — Audi A8, Audi A6 4.2, and LS460 — all suffered from front rotor deterioration in the form of hot-spotting. None of these was driven hard. Anyway, thanks for the link; very informative.

 

Those rotors look turn-able to me. Really all you need to do is turn them down to remove those pad deposits.

I own a 2022 Kia Stinger 3.3L GT2, a very good car, and some on the forums are complaining about identical front brake problems.

Long story short, replacing the front pads with aftermarket pads such as EBC Yellow, completely cures the problem. Best-case scenario is to turn the rotors before installing the new pads, and, always burnish the pads to the rotors.

The root of the problem is the USA pad compound, and are virtually dustless. Replacing the USA pads with OEM Euro-spec ones, and no more problems, but more dust.

I've never had a problem, but I burnished mine immediately after buying the car brand new.

 

In my experience, 'spirited' driving on the street is not even close to tracking a car.

For example, at Road America, our cars hit 150+ mph going into Turn-1, Turn-5, and Canada, and having to slow down to 75, 55, and 55 mph respectfully, each lap. There is no way anyone will be driving anywhere near those speeds on the street for long before being thrown in jail for a very long time.

 

welcome. totally agree.

yeah that's brutal on brakes.

 

Agree on the EBC yellows. Dust - yes. Performance - yes. Amazing bite and almost no fade.

I still suggest getting ceramics. Rotors and pads.

If you trash those quickly, you might consider changing your driving style.

It's only money.

 

just go with oem:
front right rotor: 43512-11010 $406
front left rotor: 43516-11010 $406
front brake pad set (awd/fsport package): 04465-11011 $165
front brake pad set (without sports package): 04465-11020 $165
you can order from bell Lexus north Scottsdale and it will have free shipping if you use their code no tax too if you're outside AZ.
I would really turn those rotors. doesn't even have a lip at the edge. also it probably didn't even hit the miniman thickness.
