Shaking in front end / steering wheel under hard braking, usually happens once on a drive

So yeah

Shaking in the front end under mild braking after the cars sat for a bit. seems to clear up if I stop hard.

Figure a pad is getting hung up? I checked the lug nuts and they're all torqued to 150 per spec.

No shaking while driving. It is winter here and there's lots of shit on the roads. I wonder if something just needs to be lubed?

Dealership wants $275 to look at it.

@135Hoser ..... is your ABS activating? Sounds like that to me.

Probably warped rotors

Probably just brake dust buildup. Not a real concern. It will happen with dusty pads.

Its pretty rare to actually have warped rotors. If you had warped rotors, it would be a consistent brake pedal pulse at all speeds.

If it clears up with use it is just brake pad pick up where it sits next to the disc. Nothing to worry about.

Have a look at the rotors, see if there's a spot in the friction surface that looks different to the rest.
I'm picking that there's a patch of rust that gets scrubbed away on hard braking, but returns when the car's sitting.

Mine did it, dealer did new rotors under warranty
