Clutch masters are easy, two pipes, two 13mm nuts and pull the whole clutch pedal box out of the car and onto the bench as one unit, swap bits over and refit. Get about half an hour to do them plus a bleed.
Brake master cylinders aint to bad, it is stright forward as it would seem. Tricky bit is bleeding them out again, certainly need a pressure bleeder. although shouldnt need to do an ABS bleed.
