Flushing/changing brake fluid

[njsteve]

Flushing is a wonderful thing. Your brakes will thanks you.

I usually use a hand-vacuum syphon and pull out 90% of the fluid from the master cylinder with the tube so it sucks up all the rusty gunk that has accumulated at the bottom of the reservoir. Don't pull all the fluid out otherwise you'll have to bleed the master cylinder again.

Then fill it with fresh stuff and go from there.

If you don't think you need to change brake fluid, look at this photo which is of the internal piston in my 73 after 40 years with the same brake fluid.
