New PRXB™ Pacbrakes

Extra motorhome & 5th wheel Pacbrake stopping power. This new Pacbrake extends mechanical brake life as much as five times.
Pacbrake’s new patented PRXB™ gives you more holdback at lower RPM’s in the range at which we typically drive.

control on slopes and under heavy
loads (towing)

RPM’s.
SIMPLE UPGRADE. It’s easy to
