So, due to Motuls higher % of glycol over other lower temp fluids... it means that Motul requires more maintenance then other fluids in order to retain its high boiling point. and given the general lack of maintenance that brake fluid sees in most cars... you may be better off with something that lasts longer between needing flushing.
Other wise, for brake pads... Unless you are looking to tweak your brake balance, its typically best to run the same pads front & rear.
