Finally Pulled the Trigger on 2010 LS460L
#16
So after driving my LS460L for a day, I noticed a bit of a pulsation when braking, along with a strange, non-linear braking feel overall. When I would try to do a nice steady slow down coming up on traffic, I could feel a strange "brake, release, brake, release" sensation that was somewhat subtle, but definitely there. I know Lexus OEM brakes are not the best, and the rotors are prone to warping easily. I swung back by the Lexus dealer to have them check it out. Their service guy drove the car and verified the problem. I left the car with them overnight so they could work on it. When I got it back, the service guys told me they had found the front rotors were warped and the pads were glazed -- they turned the rotors and "reconditioned" both front pads (which were nearly new, with 10mm thickness still). Note that the I assumed this would fix the problem, but now, after another day of driving, the problem seems to be back. I'm not really getting the pulsation (warped rotor feel), but I'm definitely not getting a smooth braking feel from the brake pedal if I hold it down steady. I suspect the "glazed" brake pads may need replacing. Does anyone have any experience with "glazed" brake pads?
I'm pretty impressed by how well the Lexus dealer is standing behind this used, non-certified Lexus with 91k miles, I must say. I guess I'll let Lexus know the problem hasn't been solved to see what else they can/will do to help resolve. I know many people on this forum advocate for switching to non-OEM brakes -- maybe I should just go that route. How much should it cost to switch to new pads all around (I may end up footing this bill myself)?
I also had a set of Pirelli P7 All Season Plus tires installed on Saturday. When the tire guys were working on the swap, they found one rim that had a bad bend on the inside. I had them swap this rim with the bright shiny new rim in the trunk. Another of the rims had a bit of a wobble also. I had the tires Road Force Balanced, and two were able to get to around 12-13 lbs, but the best they could do with the other two was around 27-28 lbs. Old rims, I guess. The new tires do ride pretty smoothly, I'll have to admit!

The folks at Lexus of Omaha have always treated me right and that is why Lexus of Omaha is my Dealership of choice even though I live in Arkansas. When I need dealership service I plan a trip to see my 2 sisters who still live in Omaha and setup an appointment. Always been very pleased.

Looks like we have very similar cars now! I just noticed you also have a 2010 LS460L! Nice!

Op......replace your rotors and pads with quality aftermarket. You will find that your car will brake as it should. Many of us here at CL have done this, and the difference is night and day. Centric premium rotors and Posi-Quiet pads will do the trick for ya! All for a few hundred bucks.

I doubt that the pads would be glazed if they're still new. I would keep an eye on the issue because the symptoms you're describing were exactly what I was experiencing with mine. It turned out to be a failing brake actuator, which is covered under a special warranty program. But once the warranty ends you're looking at a very expensive repair. I posted a video here in this thread showing what it sounds like:

Anytime you change or resurface a brake part, pad or rotor (or both) the car must go through a "bed in" (or mating) procedure. This is true of any car, not just Lexus. You can google this subject to no end. Service centers rarely do this procedure which results in a lot of braking issues. In short, the bed in procedure involves braking from increasingly higher speeds to 5mph (not to stop). So 30mph to 5mph multiple times; 40mph to 5mph multiple times, then 50, then 60. Once you start to brake, apply constant pressure on the pedal at about 80% force down to 5mph, letting off before the car stops. Obviously you need some clear road, so head out to the country. There are variations in this procedure, but most are close to what I described. I've fixed numerous brake issues this way, usually pulsing, squealing and vibrations. The good news is the procedure can be done at any point. Give it a try before you spend any money. Good luck.
