[VAC] Re: Exhaust brakes -/ Jake Brakes

[jim clark]

I was somewhat aware that the diesels freewheel when coasting and know from experience that trucks with Jake Brakes make quite a racket when they are used ...Their use is banned on a number of nearby freeways... I would have thought blocking the exhaust would make the diesel quieter... can someone straighten my convoluted understanding of this brake system??  A URL would be sufficient, I think...

Another Diesel wannabe

I was on a bus trip on a 56 GMC coach that had a Jake� brake (not the same as an exhaust brake, but similar).  It also is activated when the accelerator pedal is released.
