Before you go to too much fuss and bother ...
I would try "re-compressing" the pads ..(like you did when you removed the =
old ones) ..
all calipers that I've torn apart have a "square O-ring" on the caliper pis=
ton ..when the piston moves due to hydrolic pressure on the backside, this =
square o-ring deforms ..sliding against the caliper bore...when the ,pressu=
re is removed, the o-ring=C2=A0 returns=C2=A0 to normal square shape ...thi=
s pull the piston back into the bore,...giving floating clearance between t=
he pads and the rotor...If the piston was not fully retracted into the cali=
per bore, MAYBE this o-ring is not being deformed enough=20
How much gap did you have on the new pads when you installed them?=C2=A0 sh=
ould have been an easy/sloppy fit
