Brake system A guide to replacing the rear pads and discs (272 mm) on a Mk. 3 Leon with independent rear suspensi

Nice photos, Just couple of points

Cleaning up the hub face - you really should be using a rotary wire brush as you need to get the hub face spotlessly clean. You should then fit the disc and bolt it down with all wheel bolts/washers, then use a dial gauge clamped to an upright of the suspension to measure disc run-out. If the disc if running out more than 0.1mm then after a few hundred/thousand miles the pads can wear the high/low spots thinner - called disc thickness variation, this can then cause brake judder.

It's not a good idea to use grease when mounting the disc as even this can cause excessive disc run out leading to disc thickness variation & judder.

Also you didn't mention about winding back the piston/remove some brake fluid from the reservoir - although best practice you should undo the bleed nipple to expel the fluid rather than push contaminated fluid back up into the system .
