I agree. There is a compensator on the rear, which may require
adjusting. This is a dealer job, I'm afraid as they use a balance
gauge connected to all four bleed nipples.
Not too bad a job to fit pads. Remove the slide after taking out the
lock pin. Take out the inner pad and with one screwdriver in the slot
of the piston, rotate the piston clockwise. With another screwdriver
lever the piston inwards. Keep rotating and levering until the piston
is all the way in. Then remove the outer pad, clean where the pads
slide on the caliper, and refit the pads with the anti-rattle springs
in place. Make sure the cut out in the piston is in the right place to
allow the "tit" on the back of the pad to engage in it. Put a little
copaslip on the sliding parts of the pad and on the back of the pads.
Push the slide back in place (not the easiest thing to do. Make sure
the spring is right in the groove and use a screwdriver to push the
pad upward into the top of the caliper and push the slide in place.
Don't forget to refit the lock pin. Do one side at at time in case you
have to note where the various bits go!! Oh, and good luck!
