Is there any way to 'bench test' the master cylinder for an A-60 actuator ?
I have blown air through all of the brake lines to ensure they were not blocked.
I tried to bleed the brakes using the vacuum pump method but it would not draw any fluid.
I tried to bleed the brakes using the manual pump with a screwdriver but it would not push any fluid.
With the brake line disconnected at the master cylinder while still on the trailer - Did the manual process
to see if it would spray a thin stream ( I understand they have an orifice with tiny opening). But it would gush out when using the screwdriver pudh method.
But would not pump any fluid into the lines when connected.
I installed this actuator new last year and worked great. I had to replace the break away cable and now it no worky.
I am guessing it is something I did but for the life of me, I can't figure it out.
I guess double check the actuator but I don't know what else to test.
