Default Front Brake issue

Need some guidance on this issue.

Front driver side brake squeals on a stop and release. this is the only side that produces this noise. Brake clearance is still very good and this noise has been off and on since i bought the car in December. Car has about 25k miles on it and will be replacing brakes at 30k.

Thoughts....

Is the shield in the back hitting anything?

I would pull out the pads, clean the the backing plates and add a little lube (to the backing plate).

Very easy to do with basic hand tools..

I have a similar sound going on and created a thread about it. Mine is in the Rear-Passenger. It is a higher-pitch squeaking.

The dealer's response: "Noise associated with High-Performance Brakes"

Seems normal. Our brakes with oem pads and rotors all seem to make some noise at some point; intermittent. I wouldn't worry about it. My brakes have good days and bad days .

I had some squeal as I would come to a stop with OEM pads & rotors. I replaced them with Centric rotors & Stop Tech pads-problem solved.

As others have mentioned this is common with some pad compounds including the OE IS-F compound. When you are ready to replace your pads with a new set we have a couple options that produce much lower levels of dust and are noise free without sacrificing the levels of performance you expect on the street. As always we have additional discounts available for members on here.

The two most popular options are:
Project Mu NS400 PS4F160 D1365 Lexus IS-F Front
Project Mu NS400 PS4R106 Lexus ISF IS-F Rear

Carbotech Performance Brakes, CT1365-1521 (Lexus IS-F Front)
Carbotech Performance Brakes, CT1366-1521 (Lexus IS-F Rear)

Unfortunately, I have Carbotech 1521 (Bobcat) in my front and they do the exact same thing. But I have been lazy and not bedded them in. I know they would be a whole lot better if I did.

I am running Ferodo DS2500 Pads in front and stock pads in the rear. When I installed my pads I bedded them in properly. They have never made any kind of noise. IMHO, most quality (not full race) pads will be quiet if bedded in properly.

Odd. My car only makes that noise temporarily after it has rained and the brakes are drying. If it drives you nuts just replace them a little early and make sure to bed in the new set. Are you really hard on the brakes ??

He is not. The Lexus on the caliper is still silver. It turns gold when you get the brakes really hot.
