Replacing break pads

[shortstick]

I pulled the wheels off my MM trailer Sunday to check the rear seals for my
Vault hubs. When I pulled the wheels I found one of my break pads
was broken in three places and was separated from the metal plate.
First off I am assuming the the pad came unglued from the metal backing plate
and then the pad broke. What puzzles me is why did the pad separate and dose anyone
have any ideas what caused it. The other pads had probably 3/4 of there useful life left.

A couple questions about the new pads.
2. Has anyone used the ceramic pads instead of the organic type and
how are they performing.
3. Should I replace with the Dexter brand or go with a larger brake manufacturer
who makes the pads for the Kia sephia.

All the ceramics I've tried on my vehicles were the same way, initial stopping power when cold was significantly less than when they had some heat in them. For that reason I wouldn't put them on my trailer.
I want all the stopping power I can get to avoid these nut jobs on the road.

I'd get the Kia pads. Most likely cheaper and of a better quality than a trailer specific pad from Dexter.
