Aircraft; Equipment / Tooling
After an uneventful taxi out to runway 30; we were cleared for takeoff. After completing the appropriate checklist; I pushed the power levers into the takeoff detent. As we started to roll; I checked the rudder pedals for authority and found that they were jammed. I retarded the throttles and slowed the aircraft to taxi speed. The Pilot Monitoring notified the tower that we were aborting the takeoff and needed to taxi clear of the runway. After exiting the runway and completing the after landing checklist I stopped the aircraft. I looked down and saw that there was a hose and small nozzle blocking the rudder pedals. We taxied back to the gate; entered the discrepancy in the log book and waited for maintenance to come to the aircraft. They found the issue and repaired it. No further issue was found.
EMB-145 Captain reported rejecting takeoff due to jammed rudder pedals. Taxied back to gate for maintenance corrective action.
