If your goal is to reduce squeal (noise), then yes.

If you have to ask this question someone else needs to be doing the pad swap!

so that’s a yes or a no on the shims?!? Lol

Kidding aside, questioning whether you need a critical brake pad component or not is concerning. But we're all here to learn (I hope). Youtube is your friend, recommend you start there and hopefully you find; role of shims, how/where to apply brake lube, proper way to compress pistons (I open bleeder valve), clean calipers, torque specs, etc. Also, can't overlook vital step of bedding pads. If mechanically inclined, not difficult, but must be deliberate.

On my IS350 you are to re-use the shims. I had an indpendent mechanic do my IS350 brakes and throw away the old shims and the new brakes were loud as crap. Went back to them and they found out that they were supposed to keep and reuse the shims. Once they installed them the brakes were nice and quiet.

Well the cooler temps here (upper 50s-mid 60s in the mornings) have brought about the squeal. When it gets up near 80 during the day it's gone again.

If it bothers me enough as winter approaches I'll try to bed them to see if that kills it.

Brake like you mean it. No squeals.
Lightly tap on the brake, sounds like a school bus.

Might do that just to chew thru these pads and then replace with powerstops

I just want to vent about how much I hate the brake dust that accumulates on my rims. I'll spend 10 mins cleaning each wheel thoroughly and within a few days they're filthy again.

This is one of the major reasons that I don't see myself going away from this matte black wheel any time soon. It hides the dust really well. This is 300 miles since the last wash, you only see the red twinge of the brake dust in absolute sunlight from the correct angle

Doing my rotors, anyone have the caliper bolt torque for the fronts?
I'm thinking 100 ft lbs???

Front and rear.

Thank you, kind sir... I was pretty close, for the fronts. 😛

$1,414.00 for the fronts, my local dealership.

Doing the rears today...so odd that the rear caliper is torqued to 111 ft lbs. and the front caliper is 100 ft lbs.
Anyway, thanks again tecman. 👍🏾
