Today on This Old Trailer we are going to replace hydraulic brakes with electric brakes. Basically it is going to be a matter of taking off the tires, removing the hubs, go ahead and removing the backing plates and drain the hydraulic lines of fluid, and then going ahead and bolting on the new brakes. We will start off, obviously, by taking the wheels off. OK, go ahead and remove the dust cover here. It is an E-Z Lube spindle so this has a tang washer that we need to bush back down so we can unlock the castle nut right here. Just push it back down. Now we should be able to take the hub right off. The next task is to go ahead and disconnect the hydraulic lines. We have that disconnected. Now we need to pull the clip out so we can release this part here. And that is just a little piece of metal right here that you can just pry out. Alright, now we can unbolt this at the back of the hydraulic backing plate. Alright, now we can unbolt the backing plate from the flange on the axle. Now we are down to our bare axle. We will clean it up a little bit and then reinstall the brakes. 1:24
