what would be the best way to keep my brake lines from losing alot of fluid when taking calipers off for extended amount of time...say 2 or 3 days....

how would i go about plugging or pinching them??

 

Just take them off and put some newspaper or a bucket under each line. I had mine off for several days and lost a minimal amount of fluid. I left the banjo bolts in the line so they wouldn't leak as much, just don't loose the little cooper o rings that go on the lines. You'll have to add fluid anyway when you bleed them after you put the calipers back on.
