Hi, Welcome to OOF

1. Omega is very sensitive to steering geometry. A simple "alignement" done by the local "expert" is pointless. The car needs to have a FULL geometry check. Most of us use Wheels In Motion, Chesham, but if that is too far for you to travel they do have franchises around, but you won't get the OOF discount from the franchises, only from Chesham. Camber out will wreck front tyres in a few hundred miles.

2. Not unknown for the levers that control the flaps that control the air distibution to pop off. Some help might be here ....

Best bet would be to strip the pads out, clean the calipers up, check the piston moves freely, reassemble and see if things are better - personally I'd do both sides and probably put new pads in whilst there

If you stick your location in your profile there might be "someone who knows" living nearby who can help

Edited for smelling pistakes ..
