What's wrong?
The parking brake cable on these 2024-2026 Ic Bus Cesb and Evsb school buses links the foot-operated parking brake control to the brake mechanism that holds the bus when parked. A tension spring keeps the cable under the right load so the parking brake applies and stays applied when the driver sets it.
On affected buses, the spring was not coated properly. Moisture and road exposure can corrode the spring, and the weakened spring can fracture. When that happens, the cable loses tension and the parking brake can disengage or hold with less force than intended. The issue is tied to buses built with hydraulic brakes and without the powered park brake setup.
Before the spring fails, the driver can feel a clear change at the foot control. A noticeably reduced force while applying the parking brake is the warning sign that the brake is applying with reduced holding capacity.
Who's affected?
Covers Cesb buses from 2024 through 2026 and Evsb buses from 2025, all tied to the parking brake cable.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific bus is included.
What's the safety risk?
If the parking brake does not hold after the driver releases the service brakes, the bus can roll away and increase the risk of a crash. A lighter than normal feel at the foot operated parking brake is a warning sign. Schedule the repair soon and use extra care when parking. Repair is free at any franchised Ic Bus dealer.
What should I do?
- Check your VIN to confirm your 2024-2026 Ic Bus Cesb or Evsb school bus is included in this recall.
- Contact a franchised Ic Bus dealer to schedule the free parking brake cable replacement and adjustment that keeps the parking brake engaged after the driver releases the brakes.
- Bring the recall notice if Ic Bus mailed one. If not, reference recall number 25V522 when you call.
- Use extra care when parking until the repair is complete, since the parking brake can fail to stay engaged and allow rollaway.
- Call Ic Bus customer service at 1-800-448-7825 with questions about scheduling or the free repair.
What happens at the repair
At the dealer, an Ic Bus technician replaces the parking brake cable and adjusts the parking brake. The replacement parts and labor are free under the recall. This repair addresses the spring corrosion problem that can let the parking brake disengage. If you already paid for a related parking brake repair before the recall notice, the manufacturer's general reimbursement plan on file covers documented expenses. Bring your repair paperwork to the service desk and ask how to submit it.
