MCI J4500 Recall 17V360: Front Brake Hoses May Leak, Lengthening Stopping Distance

NHTSA campaign 17V360, reported June 2, 2017, 1,100 vehicles potentially affected.

What this recall means for you

Some front air brake hoses may have been damaged during installation because the routing clamps were tightened too much. The hose wall reinforcement can be harmed, and a damaged hose may leak. These vehicles then no longer meet the federal air brake standard, FMVSS 121.

A brake hose leak can lengthen the distance needed to stop the coach, which raises the risk of a crash. Owners should watch for any sign of brake trouble and avoid delaying the repair.

The repair is free. Motor Coach Industries will notify owners, and an authorized dealer will inspect the clamp tightness and replace any damaged brake hoses as needed. You can contact MCI customer service at 1-800-241-2947 (recall number SB 454), and you should also check your vehicle identification number for any open recalls.
