NHTSA campaign 21V974, reported December 16, 2021, 20 vehicles potentially affected.

What this recall means for you

A rear brake caliper flexible line on certain cab chassis equipped with the LiquidSpring C.L.A.S.S. adaptive suspension may rub against a suspension component. This can cause a brake fluid leak.

Brake fluid loss can lead to partial or complete loss of the rear brakes, which raises the risk of a crash. If you own an affected vehicle, check whether it has open recalls by entering your VIN on the NHTSA recall lookup. The manufacturer reports that all affected vehicles have already been repaired, so owner notification letters will not be sent. If you have questions, contact Arrow Manufacturing customer service at 1-712-261-3157.
