Brake Problem

[91lxaccordkidd]

my rpassanger side caliper keeps locking up on me, it would gone fin for a while but once it gets hot, i can feel it slow down fast when i push the clutch in. and when it sits and cools then its really hard to move. do you think it could be anything else causing it to lock? ooh yea when it starts to lock my brake pedal gets hard as a rock. any advice will help.

Caliper sticking. Might need to rebuild or replace the piston.
