help rear brakes

[dragginnnnnn]

i have a 2001 blaster and im trying to change the rear brake pads
it has the round pads my question is do i have to put any kind of fluid or anything in the caliper before i close it back up
thanks
or is it dry cuz when i took it apart it had fluid in it looked like mudddddd

no, it's dry. just put them back in and have the grooves all lined up. mine are screwed up because i put my pads in and i can't close the caliper up without them locking up. they're probably too thick or something. oh well, my front brakes work fine though.
