Sorry to hear about this John. Hope all goes well.
Just a quick thought. Can you take the car to get MOT'ed before SVA?
Just thought in might pick little things up like brake's, steering, etc. But by the sounds of it, they test all four wheels on the rollers for the brakes which most mot garages won't have.
Can't remember which pedal I had "adjusted" by Marlin (might have been the brake pedal).
All the best John.
