And another brake issue

[Henn28]

Wife picked me up at the airport last night in the X and I drove home. Took me one application of the brake to say “what the covfife!”. The steering wheel jumped and vibrated badly in my hands the instant I applied the brakes. Long story short, repeatable at any speed, no issues when not braking. Car stops ok with no pulling to either side tho.

I’m going to pull the wheels today and recheck all the brake work I did over the past few months (new front rotors and pads, new parking brake pads and springs), and check all the fasteners on the suspension pieces/links (all changed last year). Beyond shoddy workmanship by me and missing the torque on something bake or wheel related, or a blown out bushing (which seems unlikely with only 6k on the new links) the only other thing I can think of is a very badly warped rotor, except that they are brand new from FCP and the car just took me 2000 miles and back to hunt with zero issues a few weeks ago. All the suspension bolts are witness marked so they should be easy to verify.

What else is there I should check? Could a caliper cause this if it fails? I would think the car would pull to one side though if this were the case.

Thanks for any thoughts before I get into it gents.
