How do you bleed hydraulic trailer brakes?

Question

mastercyclender is in hitch

Answer 1

One would bleed the brakes on a trailer the same as one would bleed the brakes on a car. Check the level in the master cylinder first. If low then add to the proper level. Get a friend to operate the brakes on the car thus activating the brakes on the trailer. Pump car brakes several times and on the last time have the helper push and HOLD the pedal down. While he is holding the pedal down you loosen up the bleeder s***w to where fluid leaks out. Before helper in car releases brake pedal you tighten up the bleeder s***w first. Then he can release pedal. Repeat this several times per wheel while at the same time pay attention to the master cylinder fluid level. Dont let it run low. Add when needed. Repeat this several times on each wheel to make sure you get all the air out. After that check the master cylinder level again and add if needed to get it to the proper level. Hope this helps.
