Parts Needed to Convert 5th Wheel Trailer from Drum Brakes to EOH Disc Brakes  

Question:

Helpful Expert Reply:

Converting your 5th wheel trailer from drum to disc brakes will require new disc brake assemblies of course, an electric-over-hydraulic actuator like # HBA16 that converts the electrical signal from your P2 # 90885 into hydraulic pressure, brakes lines (if the trailer had electric drum brakes) and new hub/rotors that use the same bearings as your original drums. I suggest you check out the linked article that covers each of these items. Links to each item category are included in the article. Since your trailer already has brake flanges and a breakaway kit these items can be re-used.

You will want to confirm the weight rating of each Dexter axle on the trailer to let you select a brake kit rated correctly. I linked all disc brake kits that fit your 8-on-6-1/2-inch wheel bolt pattern. Kits come in two basic varieties, ones with hub/rotors (what you need) and ones with rotors only. You also have choices of the finish on the brake kits, which are offered in a raw finish, an e-coat finish, Dacromet or stainless steel. Prices vary (considerably) depending on the finish chosen.
