I am planning on changing the discs/pads on my 1.4 Lupo(Y).



A couple of questions



What size are the bolts that hold the caliper on and are they normal nuts or hex nuts. I heared they were 10mm?



Would you normally loosen the cap on the brake fluid reservoir before resetting pistons?



Where is the copper grease meant to be applied?



Anything else I should know before starting?
