Hello
i have tried all the tips in the FAQ and none helped nor did my LBS.
i have a zesty 514 with formula RX brakes. Im not total sure but since its came back from the bike shop when the rear brake is applied and rocked back and forth i get a horrible sqeeking/creaking noise from the brake. All the bolts are correctly tightened or should be by the shop and the disk is tight. iv tired both superstar and the original pads and it still does it. i suspect the pads could be moving back and forth slightly causing the creaking against the piston but don't really know why it would suddenly start. iv tried coper slip on the back of the pads and this didn't help.
Im completely stuck can any one help?
thanks

    Is it possible that they got lube on the discs? Have you tried cleaning them?

    could be it doesn't seem to have massive power but doesn't squeek when riding. will be cleaning and putting new pads in tomorrow but doubting it will work

    Clean the brake disc with some IPA to get any grease/oil off of it. Replace the pads, if nothing changes, ask the bike shop, seeing as the problem originated after they had worked on it.

    Think iv had a break threw some of the spokes are loose ish tired tightening them a little but don't want to mess about with it blindly. since it was my free service on the weekend should they have check for this and tightened them correctly?

    turned out it was the 6 pins the centerlock rotor mounts to they were smaller than the rotor holes so was a clearence fit allowing some play. shop has ordered knew ones i assume its because the shop didnt torque it properly
