Replacement Actuator for ACT-7.5K Disc Brake Actuator

Updated 04/11/2022 | Published 04/09/2022

Question:

I need to replace the entire brake actuator assembly for my 2010 MasterCraft boat trailer. I saw someone already asked this question on your website before. You recommend the replacement as “Swing-Away Actuator w/ Electric Lockout part # T4839100 for disc brakes”. I can’t find this part number on your website. Do you still offer it?? Thanks

For a replacement option I recommend the Dexter DX7.5L A-60 Brake Actuator w Electric Lockout - Bolt On - Disc - 2" Ball - Zinc - 7.5K # DX29FR. The swing-away actuator you are referencing was discontinued and there is no direct replacement.

The # DX29FR has a 7,500 lb trailer capacity, is designed for trailers with disc brakes, and is a bolt on replacement. More than likely you will also need a replacement swing away tongue adapter like the Fulton Fold-Away Coupler Hinge Kit for 3" x 4" Tongue # FHDPB340301 which fits 3" x 4" diameter tongues.

I have attached some installation videos for your reference.
