Has anyone used an automobile caliper on their trailer. I have been using the K brand 225 calipers for quite a while now. But like any caliper getting dunked in salt water they seize up. I am pretty meticulous about rinsing them but a short layover and they start to seize up. So as long as I have to keep replacing them I would like to install a less expensive brand, perhaps an automobile brand that will fit my trailer. I would rather replace them every year and know it is to be done than find that the "quality" calipers are frozen up again when I am ready to go.. For 80. or 90 bucks each I think I can do better. A freind of mine has the stainless steel version but has had to replace them also. Maybe not as often but for 200 a caliper I would think "lifetime". Cars drive on wet roads, salted roads, big and small puddles and they seem to keep going and stopping. And they are less expensive. A ceramic piston would be nice.
