Does it still feel firm or has it gone mushy?
If mushy, air is getting in somewhere, might have been hiding in the reservoir. If the brakes are getting squeaky then calliper could be dead.
If it’s firm but the bite point has changed it’s something mechanical.
It's firm but the bite point has changed. Could worn pads and rotor cause this? Or should the excess oil in the reservoir account for this?
Bite point shouldn't change as pads wear out. Might be an adjuster somewhere loosening off and affecting the mechanics of the lever, resulting in more throw?
That said, if you pump the brakes, does the bite point sort itself out at all?
