Soft Brakes on IS350
I recently drove my brother's IS350 and noticed his brakes seemed much firmer than mine. So I thought my brake pads were needing to be replaced as I had over 30,000 miles on them. When I pulled the tire off to replace the pads, it looked like I still had plenty of life left on the brakes. I also checked the brake fluid reservoir and it was right on the nose. Any suggestions? I had the brake lines flushed about 25,000 miles back. Do you think having this done again would make any difference?

Yeah, that's gonna be the reason. I went through the same thing myself on my 350; had high-dust pads on originally, but replaced them with lower dust StopTech Streets. Pad "feel" is definitely not as firm, and I personally do not like it one bit. Once to replace the fronts again, I'm getting Axxis ULTs.

He definitely has the high dust ones because he complains about the dust all the time. I'm not sure what's on mine as they were replaced by the dealership when I purchased the car in '10. I ordered the replacement pads off of Sewell not that long ago and I believe they are the high dust pads. Maybe I'll change them out anyhow and see if it makes a difference.

If after 2 days the wheels still look pretty much the same as when you cleaned them, you have the low dust pads.

If what you're referring to is less pedal travel and firmer feel when stopped then it could be your rear caliper slide pins beginning to seize up.
Using low dust pads requires more pedal effort to slow down the car, as with higher friction pads less effort is required. Sure they both stop the car at the same time if you lock up the wheels but each one has different characteristics for slowing down without the intention of coming to a complete stop.
In any case I urge you to look at your rear calipers slide pins to determine wether they're moving fluidly or are pretty much just stuck and the piston is doing extra work to compensate for the lock up.

In that case, I definitely have the low dust pads. You're making me rethink changing my pads early to the high-dust pads. Any recommendations? I know you can order the low-dust pads from Sewell for around $75 but are there other low-dust options?
