F Sport Brake pad squeal, Part 1,000
I took our '13 GS350 F Sport (77K, excellent condition) to a good local shop to diagnose a suspension clunk. There is another thread on that; the clunk source is not yet determined.
I do most of my own work; in this case I wanted to "put a little more meat on the bone" for them. So I asked them to service the transmission and check the brakes.
I gave them the Lexus filter strainer and 5 quart jug of Idemitsu WS equivalent ATF.
They replaced the rotors and pads. They used Textar pads, which are the supplier to Lexus. The pads cross reference to the original Lexus part number; not the TSB pads.
They did not squeak at first, but that didn't last long.
I pulled apart the passenger side to investigate. The squeal sounded like it was on this side...
They used a thick black grease on the back of the pad and shim. Messy. None on the metal-to-metal surfaces.
They did not clean the keeper pin, spring or caliper.
I wiped off and cleaned the pad backing and shim, applied a good synthetic lube and reassembled the components.
I took it for a spin; the brakes felt great and the squeal was gone. It did come back after awhile, but was much more hushed.
So today I pulled both sides apart, throughly cleaned and lubed the components and reassembled.
Brakes feel great; no squeal for now. Let's see what happens.
If the noise returns to a level I can't live with, I will go purchase the revised Lexus pads and shims.

Howdy!
i have a 2015 Gs350 and I once bought aftermarket brake pads and shims that were supposedly also a supplier of Lexus and Toyota . they the same as yours smooth at first but the squeal was just the absolute worst.
I tried another set of pads lube to quiet down the noise. so that didn't work and ended up taking it to Lexus where I was pressured into buying New rotors and pads for $1300. the comforting thing the car drove even smoother than ever. and I dont regret it. But im never buying it again from The Dealer directly. I buy all my OEM brake pads and shims from Ebay and do it myself or a local shop if im lazy.

What brand of aftermarket pads did you buy? Is your car an F Sport?
I wish I had jus done the brakes myself. I would have bought the parts from a local dealer, Lexus of Stevens Creek. They are a huge dealership and their parts department has great prics.
But so far I have no squeals. Knock on wood!
