On certain Freightliner vehicles customized by Fontaine Modification, and equipped with duel steering stations, air lines for the right-hand brakes may be routed too close to the turbocharger. This could cause the air lines to blister, melt, and eventually develop air leaks, which may lead to brake lock up, increasing the risk of a crash. Correction: Dealers will replace the air lines or relocate them, as necessary.
