Upgrade to Big Reds - help please

[TurboRuf]

I have Wayne's book but I still have a question about removing and installing front calipers.

I'm looking to swap my front 930 calipers with Big Reds. Do I have to bleed all four corners or can I just bleed the two front calipers?

Any other tips would be appreciated.

Thanks

I would bleed the whole system just for safteys sake and replace it with Valvoline Synpower sythetic brake fluid. Its got a higher boiling point to reduce loss, but dot4 doesn't absorb water and can allow more rust formation.
Get the brown fluid out of the resevoir first before refilling, don't ever push the pedal to the floor(damages seals in the master cylinder), and start with the wheel furthest from the driver and work back.

Oh yeah, only push the pedal slowly(you can put a 2x4 under to keep it off the floor). If you "pump up the brakes" when bleeding your introducing air cavitation.
