The squeeze type sprayer nozzle from a squirt bottle fits onto a plastic bottle of rubbing alcohol, and works well for this purpose.
Alcohol may be squirted through the brake lines (detached from master cylinder and caliper) if deemed necessary, followed by compressed air.
Parts, and lines, should be blown with compressed air to remove residual alcohol, and dry them.
Lightly coat master cylinder piston and caliper piston with fresh new brake fluid before reassembling.
May attach a short length of plastic tube to the bleeder valve nipple, and use a new bulb syringe to refill the system by injecting fresh fluid through the bleeder valve.
The normal routine maintenance "flushing" of the brake lines to "change" the fluid --- usually entails only removing most of the old fluid from the m/c (try to avoid exposing the supply holes at bottom of reservoir to air). Then keep the reservoir topped up with new fluid while steadily pumping it through the system to waste from the bleeder valve, until eventually, new fluid appears from the bleeder valve.
Good Luck!

Then, I use dot 5 fluid, I have had it in the rear brakes on the 1000 now for about 2 plus years and a friend had it in his entire brake system for 10 and never had any issues.
So I am gonna stay with the dot 5 when I clean or rebuild the brake system

I used a nylon broom bristle(the fuzzy end)and a drop or two of oven cleaner first and after a minute or two I followed up with alcohol to rinse. I stuck the fuzzy end in the slot and made it flex while spinning it in my fingertips. It worked like a charm, rubbed all the discoloring right off!I'll second or third the push the DOT 3 through until it comes out clean. A related question, how do you guys clean the sight glass in the front master cylinder that has old nasty stains on it? Thanks.

I know this is gonna stirr up a hornets nest, but , I have used carb cleaner followed by compressed air to clean everything out of the lines.
Then, I use dot 5 fluid, I have had it in the rear brakes on the 1000 now for about 2 plus years and a friend had it in his entire brake system for 10 and never had any issues.

I thought many carb cleaners aren't friendly with rubber parts, what brand do you use?

DOT5 is slightly more compressable, and actually has a lower boiling point than DOT4.
DOT5 is doesnt eat paint though... nor does it absorb water...
I think DOT5.1 is the way to go.
