Default Tips for plugging brake line during maint? (and other brake questions)

This week my cruiser gets a brake refresh, including all new soft lines, rotors, calipers, and pads. Does anyone have some tips on what I can use to plug the hard lines so all the fluid doesn't drain out while I'm swapping soft lines and calipers? I'm trying to avoid putting air up into the abs and master cyl. Would an earplug work? Not sure what types of materials would react or break down in brake fluid.

Here at work I've always used a piece of bulk hose mabey 2" long either 1/16" or 1/8" diamater what ever fits the flaired end tightlly and i shuve a bolt in the other end to act as a plug. And slide it up as far as you can with the bolt already init at liest 1/2" past the flare. Works perfectlly then when your done very little bleeding. Never had a issue with it breakig down or melting. And if it does who cares it's free bulk hose (for me) mabey $2.00 for you if you have to buy it

Cool I'll give that a try. I have a bunch of fuel or heater hose left. Wasn't so much concerned about the material itself, but something contaminating the brake fluid. Got the new rotors on, hopefully the lines will be coming from Dan in the next day or two.

The only way your going to contaminate the brake fluid is if you leave it open to the atmosphere. It collects moisture. Any ways your going to have to bleed it when done. So the tip of fluid at the plug will be flushed out the first pump of bleeding.

Vacuum caps are sweet. In most cases I only need one pump on the brakes to bleed and I use them religiously.

Never a bad idea to completely drain it and refill with new fluid, especially if it hasn't been done in awhile and you're adding new parts.

Hrm super good idea! And I think I have a few vacuum caps laying around. Dan's package of new brake lines, washers, and pads arrived yesterday to pair up with my mediocore new calipers from napa. (though I forgot to order new banjo bolts...so I'll have shiny rotors, hoses, calipers, pads, and an old bolt ) And yep, I'll do the full on flush again. Had flushed a few months back, but definitely will do it again. Being a n00b, just was nervous about any petroleum contamination.

Thanks all.
