Just one thing. The bike should not come to a stop when bedding in brake pads as it will cause inconsistencies in the transfer material applied to the rotor.
Find a gradual downhill gradient, as already stated, then do 15-20 hard applications of the brake but ease off before the bike comes to a complete stop. That should see them bedded in nicely.
On a side note, some pads take longer to bed in than other and some pads have a better initial bite than others. Typically those with higher metal content will take longer to warm up/bed in. If you’re not getting on with the ones you have installed try some different type pads.
Überbike Components do a great pad which they call Race matrix. Great compound. I’ve been running them on both my bikes for a while now. Good price too.
