Squelch the Squeek

[Whoops]

Theoretically possible, but less likely.

Most likely, homemade shims "ate" all the necessary clearance between the pads and rotors, causing the brakes to bind.

*First of all, without touching the front brake lever slide a thin sheet of notepad paper between all the pads and rotors....to check the clearance
*While still on a center stand, check that the front wheel can turn freely without any force or resistance...
*Open the brake reservoir cap, press the front brake lever a few times and check if there is any improvement.

Was going to make a joint reply to you and Max, but the reply window doesn't seem to work like the old forum and I can't seem to link to a post number...

I can't slip a piece of paper between them, so they are definitely touching the rotors with the shims installed.
I can turn the front wheel on the stand without much effort, however the drag is creating enough resistance that the wheel doesn't continue to spin freely like it does on my Africa Twin, for example.
I will be changing brake fluid today and give that a try to see if it is actually over-full/over-pressured. I didn't attempt this yet until I am all setup to change fluid with the 60 or so towels I need to prevent damaging the paint with my klutzy hands.

Hi all, Whoops there is a chance that adding all those pads makes the shims a bit " springy " and cause the pads themselves not to retract the tiny amount to clear the rotors as Peter mentions.
This could be a bit of a problem if they drag and heat up some, just be aware of this but good to hear the progress, seems you are on the case!
Never gave this a thought but; what keeps the pads in place, is it solely the pins or do they use a part of the caliper as well to transfer the brake force to the caliper housing and keep them aligned?
Very nice photo's by the way!
Power of dreams eh? nice touch!

I can guess you might be right as to the "springy" behaviour as the pads seem to consist of a woven mesh of synthetic, plastic-like fabric covered by a bit of a gummy rubber coating. Then the side that adheres to the back of the pad has an adhesive.

So far as the pads go, it appears to me that they hang soley on the pins and then only contact the retention clips along the top edge of the pads, as well as the open ends of the cylinders when applying pressure to the brakes. I wish I could fully know where the squeek is originating from so I can address that specifically. Like others have mentioned, it only seems to happen when you are going slowly just before you come to a complete stop, at about 5-8 mph I would guess. My thoughts are that the pads are actually chattering against the rotors creating a bit of a harmonic vibration rather than a squeek of metal on metal like you would hear in a car when the wear indicator drags on the rotor.

My next attempt was going to be trying some organic pads, but I can't seem to find a set that fits the 2017 EX.
