Drawbacks. Although Jake brakes are powerful, they’re not without their problems. Both Jake brakes and exhaust brakes can cause overheating, but the exhaust brake (which traps most of the exhaust’s heat inside the turbo and engine) is far more prone to causing thermally-induced destruction than the Jake.

What is the difference between Jake Brake and exhaust brake?
