How can I add a bleed type reversing solenoid to a DICO model 6 for drum brakes to improve backing up hill?

For a two axel boat trailer. I'm told I can't use a DISC type master cylinder as the pressure is different. Brake experts at three shops have been unable to solve my problem of dragging brakes. All brake and bearing components replaced at least once.How can I add a bleed type reversing solenoid to a DICO model 6 for drum brakes to improve backing up hill?well it is actually very easy.

Go to a boat dealership and ask for a reverse solenoid. It will have a nipple on one side and a female on the other side.

Remove the hydraulic line coming out of the master cylinder, install it there.

It will have a wire on it , connect this to your trailer wiring harness. ( you will need a 5 prong trailer harness) The wire from the solenoid will connect to the blue wire on the harness.

Then on your vehicle you will need to connect the blue wire to the reverse lights.



After you are done you will need to bleed the brake system on the trailer.
