Solo Brake Bleeding Options

[EdwardBlume]

I have a spongy brake pedal that firms up upon pumping. No visible leaks, I think the brakes just need bleeding.

Any good how to descriptions, especially how I can do it by myself? What equipment is needed to fill fluid?

Thanks,
Rob

So I'm ready to roll with the bleed.

Another question:

First push on the brakes, he pedal goes to the floor. Pump it a couple times and it firms up and holds. Let it off, pause a second, and it goes back to the floor. Do I have air trapped in the Master Cylinder? or is it at the brake bias or further in the lines.

Seems to me if I have air further up, I'm going to be bleeding the brakes for awhile.

Well, that's the way it is sometimes. Go until you either run out of bubbles. or run out of fluid...

I just ran 2 qts. through my truck to make sure the 16 year old fluid was all out. Never heard of using food coloring. Is it safe? I think I'd want to flush un-dyed fluid through after, just to make sure it was all out, personally.
