What's wrong?
The rear brake caliper flexible line on the 2019 Osage Ram 4500 Chassis, Ram 5500 Chassis, Warrior, and Super Warrior is the short flexible hose at the rear brake caliper. It carries brake fluid to the caliper while still allowing the suspension and axle to move. That flexibility matters because a rigid line would not tolerate normal suspension travel.
On affected trucks, that flexible line was routed too close to suspension components. As the truck moves, the line can rub against nearby parts and wear through its outer surface. Once the hose is damaged, brake fluid can leak at the wear point. A leak at that line can reduce or remove rear braking force.
Owners can notice abnormal brake pedal feedback, weaker stopping ability, or brake fluid leaking near the rear brake caliper flexible line. A technician can also see the problem by checking whether the flexible line is touching the suspension.

If the line needs replacement, the technician replaces it. The recall repair is available now, and parts and labor are free of charge. Osage has a general reimbursement plan on file for documented brake line repairs paid before the recall notice.
