Jake brakes were never my specialty, and I haven’t worked on a diesel engine (or any engine, frankly) in almost a decade, but if I remember correctly it basically breaches the cylander at the point of compression so that the force goes out of the engine instead of transferring to the driveshaft. I’m possibly completely misremembering though, just putting myself out there to draw engagement and be corrected because I’m curious.
