How to Determine Correct Electric Brakes, Bearings, and Seals for 1967 Avion Trailer


Im looking to replace the brakes on my 1967 Avion Camper. It is a twin axle and does not currently have a breakaway kit. If there is any way you have light assemblies that will fit it as well there are quite a few of them that are needed as well. Current magnets are round I can send photos when you reply. All the wiring is shot. While I have them off I am told I should replace the wheel bearings and seals. I have a 2011 Tundra that I will be pulling it with someday that needs a brake controller as well. It has the factory 7 pin / 4pin connector so I assume it is wired for a controller. Might as well get a front receiver for my 2007 Wrangler as well. post Christmas spending is fun. Thank you.

Ok, we can help you out with everything you mentioned, but buckle up as it's going to be a long read here. Let's go ahead and start with the brakes, and I'm sure we have assemblies that will work, but don't have any known specific fits for the brakes so what you'll need is to know your axle's weight capacity, your mounting flange bolt pattern and the inside diameter and depth of your drum. For example, the Electric Trailer Brake Kit # AKEBRK-35-SA is for 3,500 lb axles, measures 10" diameter x 2-1/4" wide (so that is the drum size they fit in) and fit a 4-bolt mounting flange.

I have added a link below to our selection of electric brakes for you to come back to once you have this info. We do have a breakaway kit that will work for you though, the Hopkins Engager Push-To-Test Trailer Breakaway Kit with Built-In Battery Charger # 20400.

Let's go ahead and move onto the bearings, and for that you will need to take apart your hub assembly and look at the bearings themselves; wipe away the grease and you should be able to see the part number stamped directly on them. If you are unable to find them, you need to use Digital Caliper # 301-17068 and measure your spindle to the thousandths of an inch where the bearings ride as well as where the grease seal rides. You can use the photo I've attached to see exactly where you need to measure.

I've also added a link below to our available bearings and seals for you to take a look at.

Okay, now onto the easier stuff, starting with the front hitch for your 2007 Jeep Wrangler, and for that you will need the Curt Front Mount Trailer Hitch Receiver # 31432.

As for the brake controller, since your 2011 Toyota Tundra has the factory 7-way, you are correct that it is wired for a brake controller so you just need the controller and plug-in harness, which is the Plug-In Wiring Adapter for Electric Brake Controllers # 3040-P if you go with the brake controller I recommend, the Brake EVN # TK63VR.

I really like the Brake EVN a lot because it is a great value due to its unique combination of quality and cost-effectiveness. I have added links below to video reviews for you to take a look at as well.
