Replacing caliper. How can I minimize the amount of air going into the lines?
I am replacing one of the rear calipers. Of course that requires the line to be taken off. Any suggestions on what to do to minimize the amount of air that will travel into the lines during the brake job? I will be bleeding it after of course.

Not sure if there is much you can do other than just bleed it good when you install the new set, only other thing you can do is find a closed nut with the same thread or a rubber cap that will fit snug at the end of the line and as soon as you take the line off cap it.
When I did mine I just unbolted the old caliper while the line still on, then installed the new caliper with the steel braded line, then unhooked the old line then immediatly connected the new one to the hard line, just bled it good and had no issues.

Nothing in the world can prevent you from bleeding the brakes once you disconnect the line. I recently changed both rear calipers/pads. I just disconnect/reconnect as quickly as i could. I went around the block without bleeding it and i still has pressure but barely. I bleed it shortly after and its all gravy now. Doesnt take long at all to do, make sure you got a buddy with you and extra brake fluid. Should flush the system anyways.

There is another obstacle. The bleeder valve on the new caliper is mangled. I am assuming that someone must have dropped the caliper on it. Instead of purchasing a new one, I was thinking of using the one from the faulty caliper. Any suggestions towards this?

I guess I am being too ****. I have heard stories where the ABS system might get air in it from removal of the caliper, which can lead to the ultimatum of having the dealer purge the ABS system of air. Oh well.

They were flushed a week ago during the last brake job. A temporary fix was done to the faulty caliper, but now my new caliper has arrived and it is time to swap that in.

highly recommend speed bleeders. should be the first "mod" anyone does to a car. i bleed my brakes by myself in about 15min (including tire removal). i have one on my clutch too
they're ~$13 a pair at any decent auto parts store, or summit/jegs/etc.
for RX8 -
Front: M8 X 1.0
Rear: M10 X 1.0

The only way that may happened is if the master cylinder was also replaced, or the idiot bleeding the calipers did not keep the reservoir full.
I have pulled and rebuilt all of my 4 calipers, install front and rear BBKs, and even changed my master cylinder to a 929 unit; and never had any problems bleeding the system. Either I am F** good or the others are idiots.
