Brake Questions, How to drain all the fluid Options

[EdwardBlume]

I'm taking the brakes / suspension off now....

Can I just drain the brake fluid via the bleeder pts, or do I need to blow them out using pressure?

Will fluid stay in the lines? How much fluid is in the whole system?

If you want to keep the fluid in the system while working on it, get a pole or something and hold the pedal in about an inch or so, or halfway down. This will seal the inlet and keep fluid in the reservoir and MC until you're ready to bleed later. Then you can remove the calipers at will.

But if you're replacing with new calipers I wouldn't want to force old fluid through them. The best thing is to bleed before the calipers are replaced, then you have new fluid in the whole system. Bleeding then is limited to the calipers.

The pedal half-held will retain the new fluid until you get the calipers on.

I've never blown them out with air. You'll get much more movement out of the fluid bleeding under pressure than air under even higher pressure.

Good Luck!
