Hydroboost Brakes for Carryall and PW My Cummins Carryall had 4 wheel Non Power Boosted Disk Brakes.  I opted to go non boosted due to the lack of available space to mount a vacuum power booster, and also the lack of available vacuum source.  I did not feel I had room for the Cummins Vacuum pump that mounts between the PS Pump and timing gear drive.  Although the brakes worked well, they lacked the responce and positive braking that would be needed in a emergency stop.   I learned of  Hydratech Braking Systems, a company in Warren, Michigan.  Hydratech Braking Systems, sells Hydroboost Power Brake Assist units driven off the Power Steering Pump.  This is the same type system as used on current production trucks.  I contacted the Owner of the Company, Mr Paul Clark to discuss my space problem.  Mr Clark offered to ship me a Hydroboost Dummy unit that I could use to see if they could make custom mounts and fit it in my limited space. My challange to Hydratech, your unit must fit a standard Helitool Power Wagon Suspended Pedal Assembly, the Hydroboost unit and Master Cylinder must have a 8 degree up tilt to clear the injection pump, and a 2 degree left angle from the  intercooler.  Quite a challange.  I shipped Mr Clark a brand new Helitool Suspended Pedal Assembly and my Master Cylinder.   When I received the completed Hydroboost Unit, it was 'Plug and Play".  Hydratech had made a custom mount to adapt to the Helitool Suspended Pedal assembly, using the same mounting bolt holes as supplied by Helitool.  The space problems required the Hydroboost Unit to be rotated 90 degrees counter clockwise.  This placed the Master Cylinder mounting bolts in a verticle plane.  A custom Billet mount plate to rotate the Master Cylinder back to its normal level position was also supplied by Hydratech. The Hydroboost unit was installed in 45 minutes. It truly was plug and play.  It was a simple matter to have NAPA make the hoses to connect the Hydroboost to my application.  Keep in mind that I am also  using a  Hydraulic Drive for my MU-2 Winch and the Hydroboost. Now I have Power Brakes, smoother than the Vacuum Type Booster on my Bumblebee.  I will be using this same system on my future PW's and a M-37.  The brake response is now equal to my Ram.  I now have to order a Proportion valve from Summit Racing to reduce braking to the rear wheels. In a normal Power Wagon application, the 8 degree up tilt would not be required.  Mr Clark, now has a 'Power Wagon Spec' and can duplicate future units for anyone wanting to go this route with there Power Wagon. Hydratech is truly a Customer Driven Company.  They bend over backwards to help a customer achieve their goals.  They are friendly, responsive and quick in their work.  You can contact Hydratech in Warren Michigan at; Mr Paul Clark Hydratech Braking Systems 586-427-6970 www.hydroboost.com Double click on any picture for full screen size Date(s): Hydroboost on my Carryall.

1 Space Problem, there is .7500" between the Aftercooler and the Master Cylinder 2 Another view of MC space  constaints when mounting a Cummins 4BTA in a WC-53 or Power Wagon 3 Space problems as viewed from the right side 4 Space Problems, there is no way a standard Vacuum Power Booster could be mounted 5 Suspended Pedal Assembly as supplied by Helitool  (on the web at www.uglytruckling.com )  The High Quality of Helitool, and the High Quality of Hydroboost was a excellent marriage in my Carryall 6 Hydroboost mounted to Helitool Suspended Pedals as viewed from the front of Carryall. You can see the Hydroboost and the MC do not extend past the side of the Helitool Mount Plate 7 Hydroboost Unit can be mounted in any clock angle position.  The final unit as installed in my Carryall has the Nitrogen Accumlator at 11 oclock 8 Side view showing my required custom 8 degree up tilt to clear injection pump 9 Right hand view 10 Helitool Brake Pedal Pivot point is a simple screw on to the Hydroboost push rod.  Its also adjustable in its throw 11 Anotehr view of the Helitool Brake Push Rod pivot point married to the Hydroboost push rod 12 Billet adapter to allow 90 degree rotation of Master Cylinder 13 Note Nitrogen Accumlator at 11 oclock.  The billet mounting adapter and hydroboost is very close to Power Wagon Spec.  The MC shown is not the one recommended by Helitool for their Disk Brakes. The MC in this picture is for illustration only.  Notice how much smaller this is than a Vacuum Powered Booster 14 Hydroboost as installed on my Carryall.  Total install time was 45 minutes.  It truly was plug n play.  It took longer to bleed the brakes than to install the new hydroboost system. 15 Hydroboost followed my required measurements exactly when fabing the mount.  The finished system fits exactly as I measured and set up the dummy unit. 16 Top view of the Hydroboost and Master Cylinder.  The Master Cylinder is a Bendix 11584, NAPA 39017 with a 1 5/16" bore. 17
