What's wrong?
The rear brake lines on 2018-2026 Arboc Specialty Vehicles Spirit Of Freedom and Spirit Of Mobility buses carry hydraulic brake pressure to the rear brakes. They also feed the anti-lock brake system modulator valve, the part that pulses brake pressure during a skid so the wheels keep turning instead of locking.
On affected buses, the rear brake lines were reinstalled in the wrong connections after chassis modifications. That incorrect routing sends brake pressure through the ABS modulator valve the wrong way. The valve then fails to manage rear-wheel anti-lock braking as designed, which puts the hydraulic brake system out of compliance with the required braking standard.
An owner or driver can see the ABS lamp come on, which indicates the ABS system is active. Treat that light as the warning sign and have the bus checked before carrying passengers again.
