I will make a strong personal endorsement of the Jordan Ultima 2020 brake control. It is a quantum leap ahead of the older Tekonsha ramped controller I used to use. It will require a little longer to install, but it's worth the effort.
My 1972 has electric brakes. Recently, I've been intersted in acquiring a 1979 Excella 500 which still retains the factory Excella-Vac brake system. I also tow with a diesel...2000 Ford F350 PowerStroke.
My truck has a standard factory installed 12V
vacuum pump to supply vacuum to operate HVAC controls, the front hubs, etc.
My question, however, is this sufficient for operating the Vacuum over hydraulic brake controller?
Should I retain the stock set-up on the 1978 (if it is still working)? OR, should I switch to a 12V
powered vacuum pump on the trailer? OR, should I replace the vacuum over hydraulic setup with a new electric/hydraulic unit such as the Master Brake System's ElecDraulic unit? www.masterbrake.com
Any help appreciated!!!
