The 2004 Honda GL1800 has 2 recalls, both centering on the same brake defect: the rear brake can continue to drag after the rider releases it, generating enough heat to start a fire and raising the risk of a crash.
When the combined braking system's secondary master cylinder malfunctions, the rear brake does not fully release, creating unexpected braking force the rider may not anticipate. Sustained riding in this condition builds heat in the rear brake assembly to the point where a fire can develop.
