upgrading drum brakes to disk on a

A bearing buddy can allow overgreasing. Be careful how much you add.

You might want to consider replacing the entire brake assembly, they are cheaper than buying all the parts individually.

Something is wrong with your adjuster star wheel if you have to adjust it every other trip.

My drum brakes have not worked well in years. I had one that would lock up while the other didn't do anything (on the other hand, one wheel locking up an screeching made people get out of the way even though only one of four trailer tires were locked) :-)

I can always tell when there is air in the line; the piston hits the stop. I have a detachable tongue but seemed to always get a little air in the lines with the quick disconnect. So I purchased an exension hose so I can remove the tongue without disconnecting the hose.

I've also replaced the master cylinder (surge side) a number of years ago and always use DOT 5. But they've never been good. On the other hand, I just towed a friends' '95 MC and his brakes were wonderful (don't remember if he has disk or drum, but mine have never worked that good, even when brand new).

As for the pix, the other problem with drum brakes is trying to clean the mess if the seal goes. At least with disk, you pull the pads off and use brake cleaner. No crevices, springs, etc. for the grease to lodge in to.

Someone in our ski club changed to disk last year (he had a fairly new drum sieze up and almost catch fire).

I need to first pull the drum, pull and replace the grease seals. Where do you get them? (I don't want to have to ask the manufacturer of the trailer if it is something standard I can get locally.

Gordon,
No natter what trailer I'm pulling there always seems to be a "leak"!!
