Brake Pad Question On Lexus LS430

I recently had my 2004 Lexus LS430 (19,000 miles, 18 months old) to the dealer for warranty work. While the car was there, I asked them to check the brake pad wear. They told me that I have 5/32nds left on all 4 and that was about half way. After I left, I started thinking about it and have a few questions:

  1. DOES 5/32nds left really mean I've only worn half the pads? How many
32nds does a new pad have?

  1. I live in Pittsburgh. LOTS AND LOTS of hills all day. And to be totally honest, my driving "could be better". In other words, I hit the brakes pretty hard perhaps more than a better driver would (I am trying to be nice to myself in public). My 2004 LS430 now has 19,000 miles on the odometer and these are the original pads. I have NEVER EVER gotten more than 15,000 miles from front pads on other make cars, although the rears usually last to about

40,000. My Mercedes' cars were even much worse...about 11,000 from front pads. Of course the Mercedes dealers would "snob rationalize" that way by pointing out that those cars have "soft" pads, implying that I should love changing pads as the price for whatever "soft" pads are supposed to do above and beyond what the rest of the world's brakes do. (I never saw any braking difference.) So this brings to mind a subquestion:

Does the Lexus use some sort of different braking system where, instead of the front brake pads wearing quicker than the rear as is usually the case, the load is distributed more evenly? If so, that would expiain my situation where the fronts are lasting longer and the rears maybe shorter. But also if so, wouldn't OTHER manufacturers be quick to catch onto this and it not be some hidden Lexus thing?

Any insight here would be helpful. Also, when I do change the pads, is there a reason (other than convenience, confidence, etc) to use the dealer, or can a decent independent handle the job. Frankly a good friend owns a Meineke Muffler franchise and he swears it's not different than a high end Toyota and he does Lexus brake pads all the time (although I suspect older Lexi where the people avoid the dealer). While I would probably not normally take my 18 month old $60,000 to ANY franchise that is geared to older, "lower end" cars, I trust this guy and I would be buying him, not Meineke.

I look forward to what you folks here know and think about this.

Lexus (and most newer Toyotas now) come with what they call an Electronic Brake Distribution (or EBD for short). This electronically modulates the bias between front and rear. Toyota has long learned that you can shorten braking distances by maximizing the rear brakes. This is usually difficult due to load variations. Everytime there's a comparison on car magazines and it involves a Lexus or Toyota, you will find that they are at the top or near the top. All this while making it last 40,000 miles. Good engineering, eh?

To be quite blunt, I believe your friend is not looking out for your best interest. If he owns the shop, he's merely advertising his business. Toyota pads are much better than most aftermarket ones you can purchase. If you want something better, they cost more than the stock ones. If you want some cheaper, that's exactly what you'll get. If that's what you wish to pay for, that's fine; just don't beguile yourself into thinking they're just as good.

I know these things because I've owned most makes and have maintained them myself. I used to use aftermarket parts all the time when I was more cash-strapped. Ever since I've made a comfortable living, I've been using stock Toyota/Lexus parts (mostly) and found them to be much better engineered than the cheaper after market parts that are merely designed to go in (and not very well at that).

Which ever way you decide to go, good luck.

As long as his friend ( or any independent repair shop ) orders Toyota parts, the job should be just as good as a dealer. I don't think replacing Lexus brake pads is any different than any other Toyota product. Just IMHO.
