Paul et. al,
It most probably is the piston sticking, since the new bearings have less
than 5000 miles on them. I suppose to check for a sticking piston you
remove the pads and try to push the piston in with some kind of lever? Am I
better off to try the rebuild myself, or send them off. To get the caliper
apart do you need any special tools? If I send them off (in the states)
where is the best place to rebuild them and will they accept the old
calipers off the parts car as a core?
Thanks,
Monte
