tangierc -

I went through almost that same process as you. TSB, etc. Resurfacing rotors and using the new updated pads have been the only remedy that has worked.

It was in the low 30s F this morning. And there was zero noise. I drove my wife's car around for a couple of hours, and there were no squeals/squeaks, nothing.

Step 2, was probably the repair procedure, on which parts to swap out for. They only printed those 2 pages for me.

 

My rotors aren't that old. So you're saying you think the fix may not work if I order the new pads, and have them put on my rotors without having them resurfaced?

 

On the contrary, I actually feel the opposite. If it were me, and I had relatively new rotors, I would resurface them for a few reasons:

• Remove any transferred material from the current pads, especially if the rotors are glazed over.
• Correct any imperfections, even the slightest, and have a fresh surface for the new pads.
• Because the rotors are relatively new, they are better suited to resurface them because they likely have a lot of thickness left. (Older, more worn rotors should NOT be resurfaced below minimum recommended thickness)

 

as tsb is for 2WD, curious if anyone with AWD F-Sports have been able to ask their lexus dealer about this?

 

Update:

It was in the low to mid 30s F yesterday. I drove my wife's car around early in the morning, and late at night. Zero squeal.

We've driven 400 miles since the pad change. Keeping my fingers crossed.

 

It's nice that they seem to have finally fixed this...but it is amazing that it's taken so long.

 

Maybe. I'll know here when I've got 5000+ miles on these brakes.

It was about 30 degrees F this morning when my wife left for work. No squeal. Not even on the initial backing out the garage.

 

Heads up folks. Here in Los Angeles I’ve been calling different dealers and they’re at least $154. One dealer had them listed at $194. I was told that they’re on back order. Yet in some sites when I just search Google for the part number I see the price listed in the $80-$90 range.

 

Really? Simple Google search for these p/n show Longo Lexus in El Monte, CA have them in stock. At $88.01 for the pads and $14.60 for the shims. Don't call parts dept, they'll rip you off. I'm about to order for local pickup from Longo, they're 10 mins from me.

 

Off topic: I want to try to replace the pads myself, doesn't look hard. My car is lowered on coilovers and is very tough to fit a standard jack underneath. Anyone can recommend a low-profile jack? Maybe something from Harbor freight for reasonable price <$150. I figure I might as well invest in a nice jack so I can take off my wheels for cleaning in the future and adjust my coilovers myself.

 

Interesting. Shims are separate in the kit? If you didn’t call parts department who did you speak to? That’s interesting that at the same dealer you’re suggesting you’d get different answers for a price.

 

@tangierc I just did a Google search and click on Longo Lexus link for each of p/n: 04465-30540 & 04945-30340. Within 5 minutes it was ready for pickup. I just return from picking up at Parts counter. The guy said these are "new and improved pads" to get rid of squeals...we shall see. Here are some pictures of different pads I have for comparison...sorry I don't have pictures of the original pads. I ran Centric Posi-Quiet with the OEM 2pcs rotors for 2 years with very little squealing. I'm running Akebono pad now with aftermarket StopTech rotors, it's squealing very badly. Notice the different material composition and the new pads are more squarish. There is also an angle trim on the corners. Hopefully with these modifications it will rid of the squeals and squeaks for good.

 

jdpdata-

I have the ACT1118 in my drawer right now as well. Those were the ones squealing like a tortured soul. I have that much meat left on mine too.

 

$150 is tough. $200 will do it.
I have one of these. It's just low enough to get under my front end on Tanabes.

 

What's wrong with these?
