What's wrong?
The air disc brake caliper on 2024-2025 Ic Bus Cesb and Evsb school buses is the brake part that squeezes the pads against the rotor at the wheel. The mounting bolts and washers hold that caliper to the anchor plate, the fixed bracket that keeps the caliper aligned while the brakes apply pressure.
On affected buses, the final stage of the bolt installation and torque process was not completed as required. That leaves the caliper mounting bolts loose instead of tightened to specification. As the bus is driven, loose bolts can back out, and the caliper can separate from the anchor plate.
There is no warning sign while the bolts are only loose. If bolts start to separate, metallic scraping noises can come from the affected wheel end. Treat that sound as a brake concern and have the bus inspected before it returns to service.
Who's affected?
Covers Cesb and Evsb buses across the 2024-2025 model years, with the same brake-system component across both models.

What's the safety risk?
A detached brake caliper can cause loss of braking ability and increase the risk of a crash. Loose bolts have no warning sign at first, but separating bolts can make metallic scraping noises from the affected wheel end. If you hear that sound, stop and call the dealer before moving the bus again. Repair will be free at any franchised Ic Bus dealer once available.
What should I do?
- Check your VIN to confirm your 2024-2025 Ic Bus Cesb or Evsb school bus is included in this recall.
- Contact a franchised Ic Bus dealer and ask whether the brake-caliper bolt inspection is open for your VIN.
- Schedule the free inspection, tightening, and missing-bolt replacement that keeps the brake caliper secured to the anchor plate.
- Bring the owner letter if you have it, and reference recall number 24V750 when you call.
- Drive cautiously until the repair is complete. Leave extra stopping distance and take the bus out of service if braking feels abnormal.
- Call Ic Bus customer service at 800-448-7825 with questions and reference Ic Bus recall 24513.
