Question

Question:

Hi there, I need to hard overhaul my 1986 Glastron Boat trailer and I’m having hard time finding the parts. The trailer is a dual axis with load capacity of 4000lbs Specifically I need the following: - hydraulic drum brakes for both axis they are different front and rear - hydraulic brake actuator coupling 6000LBS The brake on the rear axis are UFP HD 1377-10 with parking brake cable, while in the front axis I have the HD 1377 HUB and the drum brake kit differs from the other one, there is no number on it, and the bolt pattern on the axis is also different. The brake actuator now mounted is an old Atwood mount on a 3” trailer tongue. Can you help me find h to e replacement? Thank you

Okay here's what we got; for the brakes on the rear, you'll want the Dexter Trailer Hub and Drum Assembly for 3,500-lb Axles # 84546UC3 for a hub a drum replacement, # AKUBRK-35-D for a brake kit, and # BRKH10B for the mounting hardware.

For your front hub and drum, we have had in the past customers use the Trailer Hub and Drum Assemblies # AKHD-545-35-K and be successful so I'd recommend going with that.

As for an actuator, the Dexter Zinc-Plated Brake Actuator # T43397007K would work just fine as it will fit onto 3" wide trailer tongues, has a 7K capacity, and will work with 1 7/8", 2" and 50mm trailer balls.
