[Closed] Advice re Disc-Caliper setting

oh SO annoying 🙄
[b]
Set up[/b]
Forks= Fox vanilla RC in VGC
Brakes = Hope mono mini double piston (not M4)
Rotor= Hope floating

The rear set up is just bog standard 160 rotor and runs perfectly, brake off with zero rubbing - buttery smooth & spins longer than a chief whip's BS!

The front has been a royal PITA! Upgraded the front from a 160 to a 202 hope rotor. Braking power was/is brills, but I couldn't stop the rubbing regardless of shimming. So, upgraded again to a hope floating as research seemed to suggest they eradicate this sort of problem.

The two methods I've used[/b]

A
1. Opened up pads (new ones) to seat pistons.
2. fit, align & part screw bolts in.
3. Apply brake and hold
4. fit shims.
5. Tighten.

result= rubbish, rubbing more than standard rotor

B
as above to 3.
4. Tighten bolts up.

Very tempted to bin the floating rotor for a meaty fixed, any suggestions?

Why should the rear be such a POP to set up, yet the front is so .....pernickerty???
