2 Person brake fluid flush method

[chrlsful]

1,000s of cars thru the eras (no power, power, hydroboost, disc only, mix, drum only) & never hada use a brake block. The verbal communication is all ways good, easy. I use the 'special equp' when draining the whole system (attach the bottle;n hose to my regular pneumatic tool's compresser (60 gal, 3 hp)

Do I press the brake pedal all the way down?

Do I press the brake pedal all the way down?

Yes, almost to the floor. Others here are suggesting putting an object under the pedal to prevent it bottoming out.

The two person method was how my dad and I always did it. Just be sure to know what words mean what for the commands so the assistant doesn't accidentally release the brake before you close the bleeder. I've since moved on to a handheld vacuum pump, 20 Gatorade bottle and some tubing which works much easier.

Side story: I had an 03 SV650 that I bought used. After owning it for a couple of years, I decided to do the brakes and fluid. That was some of the nastiest fluid I had ever seen! When I got to the back, I pumped the lever by hand and opened the bleeder... fluid came out but slow. Did this some more and chunks of goo came out! After I finally got new, clean fluid in there I went for a ride. Apparently between the old fluid, goo, and air, my "old" brakes were spongy but it was what I was used to. The first time I used the brakes, I had the backend wiggling from the locked rear tire!! Scared the crap outta me!!
