Summary: North american bus industries (nabi) is recalling 164 my 2003-2004 45CLFW composite bodied transit buses. After prolonged use of the parker check valve, the valve body retainer may become excessively worn, and eventually break apart.
Consequence: Pieces of the valve could become lodged within the spring brake valve, potentially causing a leak or preventing air from properly exhausting from the spring brake valve. This could cause a delay in brake application of the spring (parking) brakes after the operator pulls the dash control valve, spring brakes not fully releasing, or loss of isolation between the primary and secondary circuits. This can occur without warning and possibly lead to unintended vehicle roll-away, brake drag, or in the case of loss of primary circuit, the inability to modulate the spring b rakes.
Remedy: Nabi is working with bendix to replace the parker check valves (please see 07E038). Owners may contact bendix at 1-440-329-9000 or nabi at 1-888-391-1777.

Has your Nabi been repaired?

Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.

Check your VIN with NHTSA

NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A Nabi dealer can also check your VIN. Recall repairs are free.
