Utility VS1RA, VS1DC +2 more: Parking brake — actuator
Affects Utility VS1RA, VS1DC, VS2RA, FS2CHA · 2014–2015 — about 3K vehicles.
The hazard
If the diaphragm is not completely attached, there may be internal leakage from the service section past the diaphragm, potentially trapping air pressure in the parking brake section. This air pressure in turn, if not vented, may prevent full release of the actuator unit, and may induce brake drag and may result in overheated wheelend service brakes, increasing the risk of a fire.
What to do
Utility will notify owners and dealers will replace the actuators, free of charge. The recall began on April 9, 2015. Owners may contact Utility customer service at 1-800-423-6591. Utility's number for this recall is 14E075.
