Latest update: After about 4k miles on the TSIB pads I AutoXed the IS250 for a second time. This time it was a 2 day event with a School on the Saturday and a regular Race on Sunday. I was an Instructor at the School and got a lot of laps to take students for demonstration runs. I also had a friend co-drive with me on Sunday so double the laps there too.

Monday when I drove the car the brakes started squeaking bad, worse than before the TSIB was performed. I assumed I had just toasted the back brakes since they were still original.

I went out of town for business for a week, and when I got back the brakes were still extremely squeaky under any light braking (heavy braking was quiet). And to top it off the car started running REALLY rough and the service engine light was flashing. I had the car towed in and it turned out to be a carbon build-up thing (my car was built after the valve spring update) but I mentioned the brakes while I had it there.

They replaced the front brakes AGAIN free. This time they turned the rotors, the first time they didn't. So far nice and quiet again, good pedal feel and such. We'll see how it goes.

You had Lexus warranty your pads after you glazed them at an autocross?!? That ain't right. They would have been fine again after a few hundred miles.

Who's says that OEM pads are supposed to be squeaky/glazed after a day of Auto-crossing???

1) Who said they were glazed? They were NOT glazed. Glazed brakes don't stop nearly as well, that was not the case. I'm thinking a lot of the noise had to do with not turning the rotors when they replaced the pads the first time. The AutoX would have worn the pads into the old, uneven patern of the rotors.

2) All I did was call my service writer and mention the squeaking. When I picked the car up they had done the pads/rotors without even mentioning it to me. Lexus takes care of us, that's part of what we pay for.

3) Finally, even if the AutoX HAD caused the brake issue, I don't feel the least bit bad getting service done on any part that wasn't up to the task in stock form. I was on stock tires, and AutoX doesn't tax any system any further than I could on a good back road.

Exactly. If a part can't handle a simple AutoX it does not belong on Lexus's "Sports Sedan." Look at the IS comericals, if Lexus wants to be taken seriously in the Sports Sedan segment and push the IS as a driver's car they should have no issue replacing parts that aren't up to the task of a little aggresive driving.

Again, they did not glaze. I've glazed OEM pads on my Z06, it's a very different scenario. Like I said, glazed pads don't stop nearly as well and my car was still stopping fine.

But even if I had glazed them I'd expect the situation to be handled by Lexus.

Is there a number or page for the 08's?

There is no TSIB for the 08s yet. Some dealers will do it anyway as a courtesy.

Edit, nevermind.

i really hate the amount of brake dust my 08 puts out. i tried to get a TSIB for them last time i was in service but didnt get anything. Im waiting a call back from my service manager to see if the 08 TSIB came out yet

I dont know what the deal is but Lexus replaced my 2008 brake pads with the new ones and man, there is about 80% less dust. Usually Id drive the car around for 3-4 days and the wheels would be COVERED. Ive had the car back for 10 days now and there is hardly any dust on the wheels at all. A definite improvement. I am not sure why Lexus is telling some 2008 guys no good, while others like me had it done and it clearly fixed the problem.

hello everyone -

so the dealership replaced my brake pads back in april (is 250) when it was in for service. they told me about it when i picked up the car. as soon as i drove off it seemed that they didn't work as well. i've been in and out of town on business so haven't driven it much. but today i almost had an accident while coming home from work. so i immediately called the dealership and spoke with my service advisor. he said to bring it in so they can look at it. not sure that they'll do anything or notice it, but i do!

It has been a year and do I ever like the brakes. Smoother and no dust.

Yeah I dropped the car off this AM and they called by the time I got to the office 30 mins later. Said they drove the car and checked to make sure they were installed properly and everything was fine. On the invoice they wrote that they were safe but will seem softer after the replacement. Whatever.

I still don't like the way I feel but guess I'll have to be more careful driving!

Lennox,

It has been a year and the memory may be a little 'adjusted' by time. I remember the factory pads tended to grab and took a soft foot for non panic stops. These seem to be less sensitive while still providing good braking. My IS is a 07 which also may be a difference. Of course I do drive on the conservative side even for an IS. BTW the car is BMW and I like the Lexus brakes better. That says a lot.
