    Hello everyone I have a bit of a problem with my discs rubbing against the outside edges of both my calipers. Has anyone ever had this problem? Literally run out of ideas before buying new bits. Something I did notice is when checking for warping I noticed the discs aren't flat. I used a metal ruler and there is definitely clearance between inside and outside edges. Is this normal? Any help would be awesome cheers

    Not sure what your issue actually is, a pic or additional info/bike model would help. I'd first do a thorough clean of caliper pistons/ensure not sticking, then inspect the metal clip at the end of the caliper (my adapter piece was worn and wouldn't retain the clip). I'd also spin the rivets in the rotor with a suitable screwdriver type tool to ensure full float can occur, rinse out road crud with brake cleaner.
    Rotor warpage can be measured with a dial indicator, or failing that, secure the handlebars from rotating and a piece of chalk held to just touch the rotor as you spin it will leave a mark on the high spots.
