Seriously? You had no brake messages at all prior to the red message? That's really scary. This is the first I've heard of the red screen and no brakes (although you do have hydraulic backup) with no alerts prior.

Yes, SBC is under extended warranty for 25 years. But it's all a question of what codes are showing.

This is what they'll be looking for:

Main SBC codes:
C249F Operating time of a7/3 (hydraulic unit) is exceeded
C2131 Pressure Reservoir faulty
C235C or C235A Service threshold reached
