I had Tie-Down brand with the earlier solid rotors (not the newer vented rotor so I do not know about the calipers on those)
I had the pistons freeze up within a year of saltwater uses.
My solution was to switch to the Kodaik brand after getting no assistance on reasons or solutions from Tie-Down
--Now after five years of salt water use ---I have had no NO problems wth the Kodaik brakes and we use the boat very frequently in Florida -- we also use the brakes a lot as evidenced by a recent tow of 13 hours each way.
I feel they are superior to Tie-Down -- and a few other people feel the same way.
