In the rear, there's a trick... follow the brake lines across the axle to the T where the R and L sides connect and go to the LSPV.
If you disconnect the line there, you can conveniently thread a std M10 1.25 bolt into that T on either/both sides, blocking it off. Yes you will lose a little from the line going into the wheel, but not much. I like threading something in better than the caps b/c it makes a "real" seal... if it's going to be of for a little while, and you were to forget it and jump in and press teh brake, this will hold pressure. The caps above will just blow off.

unf I can't help you on teh front, that hasn't come up for me (yet).
