How To Determine If Brakes And Hubs Will Fit Tandem Trailer

Question:

Hello, I have a 2 Axle about 3500 pounds each flatbed trailer 3/16inch traction steel deck and 2inch ball. Trailer is 8foot by 14. Extended tongue. About 26inch from the ground to the deck, axle is 2 3/8 in diameter, tire size 20.5 x 8.0 - 10 The trailer is similar to a snowmobile trailer. I was looking for these parts: Electric Trailer Brake Kit - 7inch - Left and Right Hand Assemblies - 2,000 lbs - AKEBRK-2, Trailer Hub and Drum Assembly for Electric Brakes - 2,000-lb Axles - 5 on 4-1/2 - 8-257-5UC3 and the Engager Trailer BreakAway Kit with Charger and Tester - 20099 My question is if these parts would fit the set up I have. Thank you for your time.

The # AKEBRK-2 brake assemblies will work with the Trailer Hub and Drum Assembly, part # 8-257-5UC3. The dimension of 2-3/8 inches you said your axles measure is for a 3,500-lb axle. The problem may be that the brakes and drums do not fit your spindles on your axle. You will need to do some measuring to see if they will work.

I recommend using a digital caliper like part # PTW80157. You will want to measure the spindle in the locations noted in the attached drawing. After you get the measurements let me know what you have and I will make recommendations that will work for your axles.

The Engager Trailer BreakAway Kit with Charger, part # 20099 will work with your trailer. I have attached a link to an installation video for the BreakAway kit you can check out.
