FYI UPDATE BELOW FROM SS AFTER I TRIED TO RETURN
Hello, normally when the pads appear too tight it is due to there being too
much fluid in the system from the last time it was bled or through moisture
absorption past the seals over time. The pads are all ground to the correct
thickness in the factory, and it is impossible to make them thicker than
intended by accident.
Try putting the old pads in and push back the pistons and then open the
bleed valve to let the excess fluid out. Then it should all work fine.
Another thing which happens is the pistons or the bore corrodes and prevents
the pistons moving back fully. This is calliper service time and tends to
happen on bikes put on bike racks and driven down the motorway at 70mph
gritblasting them.
I doubt there are any problems with the pads as this is the first report out
of several hundred sold. Any problems please let me know.
cheers
