bikeperson45 Posted March 14, 2015 Report Share Posted March 14, 2015 Help me guys, my wheels spinning fine when going forwards but when I'm going backwards its rubbing. Pads are on as straight as I can get them and it's very annoying Quote Link to comment Share on other sites More sharing options...
ZArgrave Posted March 14, 2015 Report Share Posted March 14, 2015 Is there any play in your wheel bearings at all? Quote Link to comment Share on other sites More sharing options...
Ross McArthur Posted March 14, 2015 Report Share Posted March 14, 2015 How are the pads worn? Pics? Quote Link to comment Share on other sites More sharing options...
CC12345678910 Posted March 14, 2015 Report Share Posted March 14, 2015 That is pad wobble on slave cyl prong/pin. The front edge of the pad will be sucked towards the rim when the wheel spins and you end up with effective toe in on the pad, whether the cylinder is set square or not. You need new O-rings (if CNC backings), new plastic backings or if like me you're still using std magura O-ring clamps just adjust the slave to cancel out the toe in.. OR you have a loose/less tensioned spoke on the opposite side to the pad that's rubbing. Find it, could even be 2 or 4 holes away from the rub, and tighten it 1/4 turn. With me on the spoke key this usually completely cheats pad wobble. Quote Link to comment Share on other sites More sharing options...
Greetings Posted March 15, 2015 Report Share Posted March 15, 2015 The pad is probably touching the rim even when you're moving forwards but due to the wear, you don't feel it. Pad wobble will cause it to jam against the rim when rotating the wheel backwards. Quote Link to comment Share on other sites More sharing options...
