Tie down I believe.

My trailer's a SeaLion.....about 3 years old bought new with optional stainless rotors and stainless brake lines.

Disk brakes on both axles, so got a chance to see how they all wore down ok.
Squeezing the new pads into place was a challenge, till I learned to tap a metal wedge in between the old pads to force the hydraulic shaft to retreat enough. Then the new pads fit in easily...
As with most jobs, learning little tricks to it is difference between struggling and easy work.

Rear seals - yeh, I was first lathering it all up with grease, grease and more grease.
I guess I reduced the grip, even though the seals tapped in tight ( used wood block to set in straight ).
Finally on 3rd rear seal attempt, I used new seal dry, and cleaned hub rim dry with solvent.
Now it's rubber to metal and seal seems correct and tight.
Pumping grease in.....the grease has to move through the bearings to migrate back out the front, so it does put pressure on the rear seal. Therefore best to pump the grease in slowly, and if possible not when it's extremely cold outside, which thickens the grease a bit.
