BRAKE LIFE
Ram Heavy Duty trucks with the 6.7-liter Cummins® Turbo Diesel engine are equipped[1] with a standardintegrated diesel exhaust brake. It
prolongs brake life, reduces brake fade and provides stopping safety
and confidence when hauling heavy loads on downhill grades.
The
diesel exhaust brake slows your truck down without using your wheel
brakes. Instead, exhaust gasses that would normally flow through the
turbocharger are kept in the engine after the turbo's exhaust inlet
closes. This builds exhaust backpressure, which slows the engine and
therefore the drivetrain.
A
wide brake pad surface area, and large brake pistons and calipers, mean
longer intervals between brake jobs and less time and money spent in
the shop.
