My newly installed XTR rear disk brake is giving me problem.
The outer piston don't seems to be retracting fully. This has cause the brake pad to kind of touching the rotor very slightly resulting in brake drag.
The drag is not very bad but the drag is still there. Although I can ignore it and keep riding but paying so much for the brake, I can't just ignore it.
Bleeding was done correctly.
Does it still need more time to run in as I have only ride it less than 5 times after installation.
Someone please help.
