NAVISTAR issued a recall on the PROSTAR model

On certain trucks, bolts fastening the brake calipers to their mounting plates (on all axles) may not have received adequate tightening torque during vehicle assembly. Loose bolts could allow a caliper to detach from its mounting plate, causing the vehicle to pull to one side when braking and could also increase stopping distances. These issues could result in a crash causing property damage and/or personal injury. Correction: Dealers will tighten the caliper mounting bolts to the specified torque.
