Brakes getting soft. (Abs light has been on for at least a year but probably not related)
The drivers side wheel cylinder is leaking bad.
I replace it and try to bleed it. Cannot get it to bleed at all.
I take out the valve and gravity bleed it overnight. Still not bleeding.

Brakes are still soft. I took it for a ride. Came up to a light to quick and hit the brakes LOCKED UP. Let off and hit brakes again. Locked up. And again. Skidding bad, locking bad when hit brakes hard.

But sure if these are related or what is going on. Amazed still cannot get them to bleed with the overnight gravity bleed.

Ideas?

You can't bleed it because it has a height sensing proportioning valve in the rear and if you have the rear wheel hanging, it shuts off fluid to the rear. You have to either disconnect to rod to the valve and manually open it or support the rear wheels on the axle.

No, the spring has to be compressed, not extended.
