I second that. If squealing bothers you, you can get special brake grease and spread between the pad and the backing plate. Also check to make sure the anti-rattle clips are properly installed.

The Hawk pads we sell come with a vile of grease in each box.

This is what Brembo uses, and what Lexus repackages from Brembo.

I used this stuff:


Worked for me

Also, FWIW, my track pads get no love at all. I just stuff them in the calipers, bed, and drive. No shims, no lube, just pistons on backing plates.

 

I have a similar (intermittent) problem with my Project Mu NS400 pads. I used Permatex copper anti-seize between the pads & shims, and bedded them immediately after installation.

Initially, they'd squeal for a couple seconds as I pressed the brake pedal, but then got quiet. That only lasted a day or two, then they were pretty much silent for a month or so. Now, I'm getting the squeal again that goes away as the pedal is pressed further or if I lift my foot & brake again. This is very intermittent & so far I'm unable to correlate it with any outside factors such as cold brakes, outdoor temps, humidity, etc.. It's completely random.

Perhaps I didn't use enough Permatex? Or maybe I should clean 'em up & use a different lube (like the Brembo stuff)?

i bought that brembo brand grease through my local lexus dealer. they didnt even know what i was talking about i had a part number ready and indeed, they found some in stock. very expensive grease but it took away ALL sounds from my brakes and held up for over 2 years now with zero noise in every weather and temperature. I believe the grease is like copper anti seize.

 

It's similar but it is electrically non-conductive and does not interfere with ABS or wheel speed sensors. It's polybutylcuprysil for what that is worth. I spent a couple of hours digging into this, and found this PBC compound is what Brembo and other OEMs specify when they want quiet braking without concerns about wheel speed data. Otherwise, I'd just buy the Permatex stuff Lou linked, because I am just about sure the only difference is conductivity.

 

Good Info Lance. that permatex brand is what most of my avid track friends use on their pad changes.

for those who do go with the brembo brand from dealer, one packet BARELY will cover all 4, so use enough and sparingly or just buy 2 (will be over 60 bucks though)

 

I just did full front Rotors and Pads.

The other times I used the Brembo / Toyota part number grease.

This time on the backing plate and shims I used heavily: (make sure all existing grease and dirt is cleaned off the shims / parts


All Pins and other contact points I used the 3M Silicone Paste


Gone probably 2-3k with zero noise

 

QFT!! I snuck off to an industrial park and bedded mine in tonight! Hehe!

 

I have the same problem after I wash the car. Just make sure you have grease on the backing plate.
