Question:
Can I reuse the existing brake lines from my old Atwood actuator?
asked by: Nick
Expert Reply:
In most cases, yes, Nick.
The new Demco DA75 actuators, such as what is used on the Demco Drum Brake Actuator # DM28CV, uses a standard 3/16inch inverted flare fitting. This is what most standard duty trailer hydraulic lines use, such as Kodiak Hydraulic Brake Hose # bh-3mfs-4-5.
Just make sure there are no cracks in the lines and always bleed the system fully after the swap. Do you need any assistance with this process? If so, let me know and we'll dig deeper. :)
