I recently bought an 08 IS-F with 16k miles on it. However, I've had a terrible time with the brakes! The dealer tells me there's a TSB on the shim kits and brake pads but they've been replaced in the 2 weeks that I've owned it! The car goes back to the shop tomorrow for another assessment... Is this going to be a constant problem for me or is the Lexus dealership a bunch of idiots?!?

I tried to upload the PDF but this forum has a ridiculously small limit for them. Google: L-SB-0044-10.pdf which describes the issue if you want to know more about it.

I just had my car in for this and they replaced both the pads and shims. After bedding them, the squeak has returned. It happens from about 10mph-0 on light deceleration - basically when crawling in traffic, which happens 50% of the time I'm in the car. It's really annoying and is going back to the dealer later this week for additional troubleshooting.

My RS 4 did this with Brembos as well, but a few stomps on the pedal at freeway speeds solved the issue. So far, no go with the IS F.
