It's not too difficult but you may need to consider a few things.
For the unions, use a proper 11mm brake spanner. They're 6 point spanners with one side missing in order to get maximum contact with the union.
For the bleed nipples, slacken off with a 6 point socket and when finished, tighten with the same. For the bleed operation, use a conventional spanner but don't tighten too much for each bleed phase or you may round off the flats of the nipple.
Check the ends of the hard brake pipes where they enter the union prior to the rubber hoses. If there's rust there ( and it may be under the plastic coating ), there is a good chance that the pipe will be seized into the union. If that's the case, trying to turn the union with the brake spanner will result in the pipe twisting and fracturing.
Ensure you don't empty the ABS pump. That can be a whole lot of hurt and in some cases will require dealer work to rectify ( the manual does have a bleed procedure for it which may or may not work! ) and you have to get to the dealer with no brakes available.
If you do fit braided hoses, make sure you transfer the anti-chafe rings from the old front hoses to the new. The diameters are different so you'll need to be creative in keeping the chafe rings in the right place. I used some cable ties but there are probably better solutions.
The fluid capacity for the whole system is IIRC 400ml. I just managed to renew all the fluid with only one 500ml bottle of Castrol Response fluid ( plus some old stuff I had in the shed to put in the jam jar ). I should probably have got a 1 litre bottle and saved myself a little stress.
Have drip trays ready and plenty of paper towels.
As each corner is finished, clean up brake fluid spilt on the car. It dissolves paint.
