In the pictures you’ll see that I removed the circular disk that closes to create back pressure. I drilled out bigger holes and added a spring loaded disk to it to control the amount of back pressure required to open it. Theoretically it should hold that pressure regardless of RPM, heat, etc...

I finished a cross country trip hauling 5000 lbs. in the bed and towing a 5000 lb. jeep behind the deuce and I have to say that an exhaust brake is a must for any hill driving. The brake seems to have steadied out and creates about 24 psi back pressure at 1000 rpm and 30-35 psi back pressure at...

The way the butterfly valve in the Pacbrake is setup and the way it turns wouldn't leave enough clearance on the other side, there's just barely enough clearance as is.

It shouldn't have too much problem surviving the heat, but the pre-loaded force may decrease as the spring reaches those temperatures. I'll have to test it out at those temperatures and report back. It does have an interesting sound when it's working, more of a "pshhhh" when operating, but not...

So I ended up making a pressure relief valve in the butterfly plate for the exhaust brake and designed it for 25-27 psi backpressure. Still need to take it out for some testing/fine tuning after I figure out the front drum brakes, but glad to say it's done. I also installed a pressure gauge...

Thank you guys for the great advice. I'm going to leave the valve springs alone for now. I should receive my pressure gauge in a few days and will be able to tune the brake once I get that it. Just finished installing a pyro and plan on doing a brake adjustment today then taking it for a drive...

Every installation manual I can find from Pacbrake states that the direct mount to the turbocharger is the preferred method since it minimizes the chance for exhaust leaks. The air cylinder is pointed in the other direction with the fitting for the airline approximately 8-10" away from the turbo...

Finished up installing the exhaust brake today with an adapter from the turbo to the exhaust brake. Had to dis-assemble and re-assemble the MAC Air Solenoid 55 series to make it an internal pilot and plugged the external pilot hole after rotating the pilot housing 180 degrees. The wiring for...

Hi, I've been using this site for awhile to get my Deuce fixed up. Currently in the process of installing a Pac Brake C20373 on the deuce. So far I have removed the stock pipe immediately after the turbo and have the flex pipe extended out and attached to the brake (took a good beating with a...
