0 gearhead204 Posted January 8, 2017 Share Posted January 8, 2017 yep, a good quick shift aid when going up hill! but abut worthless as a compression brake, it does change the sound of the exhaust but that's about it!

0 mrsmackpaul Posted January 8, 2017 Share Posted January 8, 2017 I gotta agree makes a sound but not much more There is a fella out here who reckons he modified the Dynatard and they worked much better I have never heard anymore about it maybe worth looking into ???? I guess all that has to happen is the hydraulic stroke needs to be made shorter so the valve is more closed off increasing the compressor effect maybe one day when I have nothing to do I will look into this This bloke reckons he removed a O ring and the effect was apparent, he thought he had a problem of three or not working right as it turned those three or 4 were working right and the other two werent but worked more like a jake brake when he had them all apart two were missing a O ring and he didnt know which way it had to be with the extra O ring or with out he found out it was meant to be with the O ring but then the Dynatard was useless so he pulled the O rings out and reckons it works like a Jake brake now Paul Quote Link to comment https://www.bigmacktrucks.com/topic/48284-jake-brake/#findComment-357641 Share on other sites More sharing options...
