Recall 11V512 affects 226 2002-2007 Great Lakes trailers with noncompliant air-brake ABS equipment. Repair will be free at any franchised Great Lakes dealer once available.
Great Lakes is recalling 226 2002-2007 trailers, including Single Drop, Wallboard, and Pup models, because the MSQR 5000 brake valve assembly lacks the required antilock brake system and ABS warning light. Those defects fail the air brake safety standard and increase crash risk; the Great Lakes dealer repair will be free once available.

What's wrong?
The affected 2002-2007 Great Lakes trailers use an air brake system, which relies on compressed air to apply and release the brakes. In that system, a quick release valve helps vent air pressure so the brakes release when the driver lets off the pedal. The ABS system is supposed to help control wheel lockup, and the ABS warning light tells the driver when that system has a fault.
On these Great Lakes trailers, the installed MSQR 5000 differential pressure regulator and quick release valve device does not include the required antilock brake system or ABS warning light. That means the trailer was built without the required brake-control and warning-light setup for this air brake configuration. The problem is a missing required system, not a part that wears out over time.
There is no warning sign before failure. Because the warning light is part of what is missing, the driver does not get the normal ABS fault alert from that trailer system.

A matching year, brand, and trailer model does not guarantee inclusion. Check your VIN to confirm whether your specific trailer is included.
What's the safety risk?
The trailer's air brake system was fitted with an ABS unit that does not meet the federal ABS definition, and it lacks the required light that warns the operator of an ABS malfunction. That reduces warning and braking safeguards under normal and emergency conditions, increasing crash risk. Repair will be free at any franchised Great Lakes dealer once available.
What should I do?
- Check your VIN to confirm your 2002-2007 Great Lakes trailer is included in this recall.
- Contact Great Lakes customer service at 1-920-842-2012 to ask whether the free compliant MSQR 5000 regulator and quick-release valve replacement is open for your VIN.
- Reference recall number 11V512 when you call Great Lakes or a Great Lakes service contact.
- Bring the owner notice if you have it, and ask for the compliant replacement unit listed in the recall remedy.
- Avoid operating the trailer until Great Lakes confirms the repair path, because the ABS equipment and ABS warning light do not meet the braking standard tied to this recall.
What happens at the repair
At the dealer, a Great Lakes technician replaces the MSQR 5000 differential pressure regulator and quick release valve unit with a compliant unit.
