Doesnt the actuator slide in to the front of the trailer frame? Thats the only kind of actuator I have ever seen for surge brakes. You only need to snip the solenoid wire (blue), disconnect the brake line from the solenoid, then remove the two snap rings on the large pins and pull the pins out. At this point the actuator will slide out the front of the trailer frame member. Reassembly is the reverse, then bleed.2008 Pantera Classic2014 Mercury Pro XS 200
