Brake pads and rotors at 14.6k miles?

If Lexus had used smaller rotors and less aggressive pads, then everyone would be complaining about that. They stepped up, put large calipers and nice big brakes on the front of this car, and the performance difference is noticeable. It's conversations like these that make automakers water down great cars and make them more vanilla.
I'll gladly clean my front wheels more often and buy brakes every 15k miles if it means I get GREAT brakes as a tradeoff. In my opinion, the brakes on this car are fantastic, and if you want smaller brakes for added longevity, please consider an ES350.
This car is supposed to be geared towards performance...please let Lexus keep it that way.

Sorry if the intent of my post was misinterpreted. It was not to suggest reducing braking performance, but to keep it at the current level, with increased brake life expectancy and reduction of excessive dust.
Here is how it can be done. The current rotors and pads require harder pads to create the high amount of friction for "performance" stopping power. The answer is larger rotors and pads with more swept area, thus more friction, thus more stopping power. Current equipment which has a smaller swept area creates more wear and dust because of the increased force of harder pads on a smaller area. Yes the larger equipment will produce unwanted heat..this can be mitigated with drilled/grooved rotors...initially more expensive but less than repetitive premature replacement costs.
The point is not to reduce braking performance, but to design the equipment in such a way as to enhance brake life and not build in more frequent service costs to the benefit of Lexus and dealers. In summary, superior braking performance can coexist with longer brake life. All it takes to make it happen is the will of Lexus.

Using drilled or slotted rotors means you can't machine them, so you're replacing every time. You're also looking at pads getting chewed up quicker by the holes/slots, which will create brake dust.
I'm sure you can tell by now that I think cross drilled and similar rotors are mostly for looks...modern pads don't outgas as much past break-in, so the benefits of cross-drilled rotors are negligible unless you're really kicking the crap out of your brakes on a track. Cross drilled rotors can even increase stopping distance and cause premature pad wear...you're essentially decreasing the surface area of the rotor by taking material out of it, and creating uneven surfaces for pad material to cut and collect.
I think the solution is to buy a different type of pad that doesn't dust as much, and try it out. Our rotor size definitely isn't the culprit, though.

well the idea for drilled/slotted brake rotors is to increase heat flux out of the rotor during heavy use. this reduces brake fade. actually, the brakes on the 350 are ventilated, a nice gesture by Lexus since indeed this car is geared toward performance.

Are they telling you you have to replace your rotors? or just the brake pads...if youre complaing about brake pads at 15,000 miles. stop. If they're saying the rotors need to be replaced at 15,000 miles. then I can understand your griping. It sounds like they're trying to make a quick buck off of you. Unless your rotors are warped or you can see the other side of the rotors...i think you just need new pads. Get a second opinion.

I took my 350 in a couple of weeks ago for service at 13k miles. The front pads had 10% left so they went ahead and changed them. They also refinished the rotors. After I picked it up, the car shuddered everytime I braked (rotors were refinished with too much end float) so I took it back. They replaced the rotors free of charge. I found out later that the IS350's brakes can't be refinished, they have to be replaced. As long as the thickness on your rotors is to spec, there's no reason for them to replace them when you replace the pads. Unless of course the rotors are scored and have deep scratches.

I could understand spending $700 for a brake job on a higher end car, but wow, that's a lot of money to be spending every 15k miles just on brakes on a $40,000 car.
I just clocked a little over 20k in less than a year of driving (80% of those are freeway miles), and you got me a little worried. I have yet to hear any brake noise, but to be sure I'm going to have to take it in soon.

Looks like tires and brakes are going to be one of the most expensive parts of operating this vehicle. Let's see, pads/rotors = $700, 4 tires = say $1,000. If these last only 15,000 mi that means 11 cents per mile.
If Gasoline averages $3/gal like it did in the summer, and at an average mileage of 25 mpg, fuel cost is 12 cents per mile.
So fuel, tires and brakes cost 23 cents per mile. That's not cheap by any means.

According to the maintenance schedule, how often does it say the brake pads/rotors need to be changed?
I know it's off the topic, but a friend of mine had the same problem with her Mercedes ML350. It was a brand new car with a little more than 5k miles at the time, and she had the same problems with her brake system. She took the car in and they had to replace all 4 rotors along with new brake pads. The worst thing about her experience was that she had to pay for everything. MB refused to cover it under warranty. She had to pay something like $1200 for it.
