I bled the brakes on the GP tonight and all went well...until I tried to close the last (front driver's side) bleeder screw. It was stuck open, I ended up stripping the head while trying to close it (rookie mistake of using a 12 point box wrench), and I could not get it closed with pliers or channel locks. I ended up pounding a socket on and twisted the thing off. It was pretty corroded and probably should have been replaced anyway. The replacement went on easily (I picked up an offset brake bleeder wrench while at O'Reilly's) and I re-bled that corner until there were no air bubbles. Is re-bleeding that caliper alone adequate or do I need to re-bleed all four corners to be safe?
Bleed 'em again?

Did the master cylinder go dry(empty) while you traveled to O'Reilly's?
Only re-bleed all 4 corners if the master cylinder went dry!

It got low but not dry.

Then just rebleed the one! But, it probably doesn't need any more bleeding if you've just done it/them all. Did you get a new bleeder valve? Just screw in the new bleeder valve, it's already been bled! Right?

New bleeder valve went in nice and easy, air got pushed out on the first pedal push, and the fluid was clear. Did another two presses of the pedal to make sure no additional air was trapped.
why would you think the other 3 would be affected? If the master did not go dry, the only way the other 3 would be affected is if a bubble of air traveled up to the master and then traveled down one of the other 3 lines. Pretty much impossible.

I figured as much but wanted to play it safe. The brake line goes up from the caliper and then down again before going through the firewall into the engine bay. An air bubble would have to defy gravity to make it in to another line but I didn't know if vacuum or pressures in other lines could make things behave other than how I assume.
