Electric Brakes for Fifth Wheel

Just got done converting my Montana to disc last weekend. Took two days and mounting the rotor and calipers were no more difficult than changing out drum brakes. In fact was easier since everything was new and didn't have to clean anything up.
It was pretty easy to run the brake lines i just measured and got pre-flared lines in the proper length to avoid the hassle of flaring. Mounted the actuator in the front bay underneath the reservoir for the slide hydraulics.

Have not had a chance to really give it a good test yest but the little bit of driving I have done is WOW will NEVER use electric drums on a trailer again.

I went with the Kodiak 13" rotors standard finish with e-coat on caliper and mounting plate. Actuator is the Titan Brake-Rite EHB, both from Etrailer. Grat place to deal with.
Bearings are US made Timken bearings from Amazon and all the brake lines/fittings from local auto parts store

The cost is more, around 1,500 for complete setup not including installation vs. around 400 to replace drum brake pads with backing plate. This would assume your bearings, drums and wiring is all in serviceable condition.
The up side of disc is easier visual inspection of rotors, pads and grease seals. You don't even have to remove the wheels. And since they are floating calipers no need to do any adjusting.

If you can afford the cost difference and have some basic mechanical abilities or have a friend that does that might make it more affordable.

Here are some links to drums replacements you were considering and also to the disc setup I installed
