Mack is recalling 331 2011-2013 Pinnacle (Cxu) trucks because the MGM Type 24 J-series piston parking brake chamber can leak pressure and leave the parking brake dragging after release. Dragging brakes overheat components and raise the risk of fire; Mack dealers will perform the repair free once the remedy is available.

What's wrong?
The parking brake chamber on the 2011-2013 Mack Pinnacle (Cxu) is part of the truck's air parking brake system. These trucks use an MGM Type 24 J-series piston parking brake chamber. When the parking brake is released, air pressure in the chamber holds the parking brake off so the wheels turn without brake drag.
On affected Mack trucks, the brake chamber leaks pressure in the axle brake assembly. With less pressure available to keep the parking brake fully released, the parking brake stays partly applied while the truck is moving. That brake drag creates heat at the brake components instead of letting them run free after release.
There is no warning sign before failure. An owner or driver needs to treat unusual brake heat, dragging, or a parking brake that does not release cleanly as a reason to stop using the truck and have the brake system checked.
Who's affected?
Spans the 2011, 2012, and 2013 model years for Pinnacle (Cxu) trucks, all tied to the same air parking-brake component.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
Overheated brake components can start a fire. If your VIN is included, schedule service soon and ask the dealer whether the truck needs inspection before regular use. Until the dealer checks it, use caution and stop using the truck if you suspect brake overheating. Repair will be free at any franchised Mack dealer once available.
What should I do?
- Check your VIN to confirm your 2011-2013 Mack Pinnacle (Cxu) is included in this recall.
- Contact Mack customer service at 1-800-866-1177 to confirm whether the free brake-chamber repair is open for your truck.
- Ask a franchised Mack dealer about the brake-chamber inspection and replacement that fixes parking-brake pressure leaks and brake drag.
- Reference recall number 13V153 and Mack recall SC0369 when you call.
- Avoid driving if the parking brake drags, the brakes smell hot, or brake components overheat.
What happens at the repair
At the dealer, a Mack technician checks the MGM Type 24 J-series piston parking brake chambers and replaces the affected chambers as needed. The recall filing says the brake chamber replacement is free of charge. Do not assume the final dealer repair can be scheduled for every VIN yet. If the repair has not opened for your truck, the final dealer repair will be free once available. Ask the Mack service desk what they need to confirm coverage for your specific truck before bringing it in.
