Pac brake lubricationby Tom Jones
At the time of writing, the recommended frequency for lubricating a Pac brake is once a year for vehicles used all the time, or every 4 months for vehicles exposed to excess moisture or seasonal use.
PacBrake sells a synthetic lube made for the job. The recommended lube points are the cylinder pivot ends, the brake shaft, the cylinder rod (when extended) and a few drops in the cylinder air port. Cycle the Pac brake electrically or manually after lubing.
Getting to the Pac brake in our coach merely involves lifting a hatch in the bedroom floor. Yours may be accessed differently.
