dealing with a Chevy Express 1500 van at the moment. Had to replace the brake master cylinder and two rusted through brake lines. Bled the system till blue in the face....but NOOOOOO...the delightful ABS pump this sits under the drivers seat has gulped air and will not purge without use of some very spendy code tool/reader gizmo. Piece of crap design. Were it mine I would buy a REAL proportioning valve from an earlier 1/2 ton van and trash this electronic black hole. Any time you complicate a system it will assuredly come back and bite you hard in the bum. The kid that works with me is getting a real education in blue air of late!
I am going to try to fool the thing on a stretch of the lane. Failing that, I am off to relay land with a jumper wire and an ohm meter. Perhaps a sledge hammer would be more useful...
If it does not have glass head lights I refuse to work on it from now on. Done with stupidity.

Pretty much unworkable by the average person now.I saw a fresh restoration of a 65 mustang convertable,289 v8 with c4 auto go for 24 thousand,why would you buy a depreciating monster for so much more,vrs a classic that only goes up in value? The value of my 1959 VW transporter goes up every year.Same with my 1969 Jeep Commando and my 1965 VW Baja Bug.
I think we have engineered ourselves into a corner and are too stupid to admit it. I let the van run and warm up and bled the brakes as one normally would-this after sitting over night. Shut it off and did other things for a couple of hours and repeated the process. More nasty fluid came out. Took it out on the lane which has a covering of leaves and whammed the brakes on. The ABS kicked in and the brake pedal went nuts for a minute or two as the stupid thing cycled. Back to the shop and bled the brakes yet again. More goopy fluid. let it sit for a time and back to the lane for another slamming. Bled the brakes yet again and FINALLY got clear fluid at all four wheels. What moron designs useless crap like this???!! It has full pedal brakes now, but i personally would NEVER trust a vehicle with ABS on it. If I ever get conned into working on another one of these tubs of poo I will only do it if I can remove the ABS and put a real working proportioning valve on it.
You have some good rigs there, Spuds. Hang onto them. I have thought for decades that engineers who could not cut it at Ford wound up at GM. If they flopped there, it was Chrysler for them. Fail again and off they go to Intertrashional Harvester or NASA. Seems about right...
