Finally happened to me (PMIII issues)

After 3 TGP/TSTEs I finally had a near death experience with my brakes this A.M.

I think the ABS pump is failing  as my front calipers have been dragging for a few days and this A.M. they failed (front brakes were smoking) and I had a high idle (3k until I shut it off when in Neutral).  With the system depressurized pump runs for 25 seconds.  Also it only takes 14 pumps of the pedal and the system is depressurized.

If its something simple I'll keep the ABS, if not its VAC brake time for me.

Last weekend doing some preventive maintenance I sucked out the old brake fluid, replaced it with some DOT III/ IV, didnt take enough out to need to bleed the Master Cylinder unit.  Took out all the relays cleaned them up and reconnected them.

Ends up 2 of the 4 pistons (one each side) were partially frozen & the brake fluid was old and dirty.  No one local sells caliper rebuild kits so I got both front calipers @ $30+ $15 core charge.

Brakes have never worked better, replaced front calipers and bled out all calipers (so complete fluid flush).
