the pads are definitely letting go of the discs, in that there is no heavy binding, or pressure there, but they are still touching, and quickly stop the wheel from spinning freely.

As the bike is stationary it is not a rolling issue for example warped discs, or a buckled wheel, both of which can cause discs to snag. good luck. Hmmmm, I was hoping you wouldn't say that! Good point, so I did your, apply the brakes / lever out slowly / spinning the front wheel, and.... well... the pads are definitely letting go of the discs, in that there is no heavy binding, or pressure there, but they are still touching, and quickly stop the wheel from spinning freely. In comparison, the rear lets go, and the wheel spins freely. So from that I think that the front caliper seals have aged, lost their flexibility, and, well, probably need changing, darn it! So as well as probably changing the Master Cylinder Seals, I am going to have to change the Front Caliper Seals as well ! I will try and take a video...Cheers, Mitch...

Remove the lever and grease the point where the lever pushes the master cylinder piston with something like red rubber grease, this is a common problem and often misdiagnosed as a master cylinder issue.
