Draining brakes for stainless line upgrade

Message

I've gotta install an extended stainless brake hose to the front in place of the stocker rubber one.

What steps do I need to take? I have the reservoir unhooked from the handlebars as they do not reach. I must also get the hose out from 2 grommets (one on the horn bracket, one on the fender).

Do I drain the reservoir and line through the bleeder screw on the caliper? Does it matter? Or is the goal just to clear the lines (caliper too?)

I'm thinking of just dumping (or sucking out) the reservoir fluid into a drain bucket, then opening the bleed screw on the caliper to clear the line. Then when that is satisfactory, undo the line from the caliper.

I am aware to take precautions for the paint as brake fluid is not good for it. Do I need to remove the caliper from the disc rotor in order to prevent any mess on the rotor? Am I overlooking anything?

When I've done it in the past, I place a bit of tubing (similar to the air tubing for aquariums) on the bleeder valve which I then run to a bottle. I then just perform the steps of bleeding your brakes to get all the fluid out of the lines and the master cyclinder. Once no more fluid comes out, then you should be good to go with unhooking. You'll probably have some residual fluid, but nothing major.

After all said and done, spray some brake cleaner on your rotors() in case there were any stray fluid that hit your rotors.

Good good. I picked up some vinyl tubing today for that bleeder screw. I figured I'd need it for sure bleeding the brakes.

I pick up my new brake line tomorrow and hopefully my new banjo bolt brake light switch arrives tomorrow as well so I can wrap it all up in one shot.

Thanks for the input.

So, since you're already there, is anything interesting going to happen tomorrow?

I just picked up my new line today. Though it is a little on the long side. Will this matter at all as far as effectiveness is concerned? All that matters is the brakes are properly filled and bleed, right?

Well duh....vehicles have long brake lines

I live in Nagoya, and im a motorcycle mechanic. Where is Misawa. Ive never heard of that place. Getting all of the brake fluid out isnt as important as all the air
