The Jacobs Compression Release Brake® takes the load off the foundation brakes, turning your power-producing diesel engine into a power-absorbing air compressor using a compression-release mechanism.

Benefits 

• Capable of 85% of vehicle braking needs
• Enables faster downhill control speed
• Reduces slowing time/distances on flat land, slowing a heavily loaded vehicle from 90 to 70 kph in 30% less time and distance
• Low cost of ownership
• Maintain higher average speed
• Significantly reduces brake wear
   

How It Works
When activated, the Jacobs Engine Brake® opens the exhaust valves near the top of the compression stroke, releasing the highly compressed air through the exhaust system. Little energy is returned to the piston, and as the cycle repeats, the energy of the trucks forward motion is dissipated, causing the truck to slow down.
