i have a king trailer with surge drum brakes. this spring i need to replace all of the shoes and hardware for wear and rust and was thinking about switching over to the stainless disc brake set up. does anybody have this style or better yet switched over from drums and have an opinion on disc over drums? the drum washout doesn't do a whole lot of good and i would think that spraying off the calipers would be a snap. i know i would have to install a backup cut out valve also and do a little wiring, but it might be worth it. i was also thinking about using the oil bath bearing setup, seems like a lot less maintanance. any input would be great!
