defo got a problem somewhere
i fitted a set to a rst coule years ago now, no probs with binding or locking up
was a great upgrade tbh,
check that the calipers are winding back easy enough
and that the fluid is returning to the master after the pedal is released,
as this is a common fault with the newer escorts, the flexi pipe collapses internaly and doesn't let the fluid return, so the brakes bind on
