Brake line/ bleed question

[Jupiter Rover]

I just got done installing some rears spacers on my discovery. But, I had trouble with the passenger spring getting back in with the spacer so I disconnected the brake line from the caliper and I lost about 3/4 or so of a cup of fluid.

Do I just re-attach the brake line and top off the reservoir with fluid and bleed only that brake? (I rented a fancy brake bleed kit from advance auto)

Or do I have to change all the fluid and bleed all 4 brakes.

Thanks.

Reconnect, top off with brake fluid and bleed that one side at the least..... only takes about 3 minutes to bleed a corner...... dont need a kit of any type unless you are doing it by your self...... This way will be messy but fast........ break loose the bleeder screw and very lightly retighten...... have an ass-is-tant press the brakes and hold.... while holding you open the bleeder screw for a breef second..... and retighten...... have them release the brakes..... repeat...... press - open - close - release..... do not let them release the brakes till you have closed the bleeder or you have just waisted time.......... I say it out loud to the helper...........
"PRESS (i open).........(i close)... RELEASE"
"PRESS (i open).........(i close)... RELEASE"
"PRESS (i open).........(i close)... RELEASE"
"PRESS (i open).........(i close)... RELEASE"

wow.. that was longer than it had to be..... sorry.. im tired!

Forgot to mention...... you are looking for a steady stream to come out with out air bubbles.......Bleed all four corners if you have time and it will keep your brake system in tip-top shape as they say to do this every 2 years anyway........ After about 7-8 pumps of the brakes..... check and top off the brake fluid... you do NOT want to run out of fluid in the M/C!.... later, Kelly

Put a tube around the bleeding nipple and let it flow into something. No mess.
