Braided hose fittings

Does anyone know what ends the A4 has for getting a set of braided hoses made up?
Mainly the standard fitting to the car side of the hose, as I need to have a different end on the caliper as they'll be going onto brembos, plus they'll need to be made longer as the disk on there are 280mm and the new ones will be 323mm (so need to be at least another 20mm longer)
Also, is there anything wierd and interesting I should know about changing the hoses, or is it a straight forward swap?
