No Brakes
I had previously posted the problem with my brakes, but I can’t find it. Sorry to start a new thread on the same problem I'm having.
Took my Discovery to a neighborhood mechanic (#1) bled the system, pressure fine. But he suggested I have the ABS checked out.
Two weeks later, no brakes.
Took it to another mechanic (#2) who electronically checked the ABS and found no problems. Bled the brakes.
Two weeks later, no brakes.
Take it back to mechanic #2, replaced the flexible brake lines, bleeders and flush and replaced the brake fluid.
Two weeks later, no brakes.
Take it back to mechanic #2, replaced both front calipers (his suggestion).
Two weeks later, no brakes.
Now should I replace the rear calipers, master cylinder or is it something else? I can get decent pressure it I pump the brakes, but if I need them for an emergency stop, nothing, to the floor. I’m at a loss and my mechanics don’t seem to have any ideas (or their happy me bringing in parts and charging me labor). There are no leaks and driving this thing is dangerous.

Well, I,ve had two different shops work on this problem and they have not told me that they found any leaks. I can't imagine any mechanic letting me drive off with a leaking system. Also, I've checked the reservoir constantly and the level never changes.

After each repair attempt, the pressure is good, but over next two weeks it gets gradually worse. Eventually, it can go to the floor if I don't have a chance to pump them up.
As an example, in the morning when I back it out of the driveway, there are little or no brakes.

You are loosing brake pressure either from not enough engine vacuum or the master cylinder is bad, it has zero to do with the ABS.
You can confirm this by removed the ABS PUMP fuse from the fuse box under the hood, your problem will remain.
Start with the vacuum booster line, booster and master cylinder.
Always remember to KISS when working on cars, Keep It Simple Stupid.
Brakes work off of engine vacuum, no vacuum, no brakes.
