I have never once had to use a scan tool, pull a fuse, stand on my head or call a Jamaican voodoo priest to get brakes bled on a 90's Chev truck.
It can be a pain in the ass, but with 2 people, rather easy.
One needs to pump the pedal with the key on, and hold. Key on so you can see the red brake indicator.
If the indicator is on, pump again, may even have to kick the pedal quickly to get it to go off.
When the light is on, the prop valve is closing off fluid to the rear.
Hold pedal.
Guy #2 opens right rear bleeder while #1 keeps pressure on pedal.
Close bleeder. Repeat process until no air.
Then go to left rear.
then right front.
then left front.

Or, just take the *frenching thing to someone who can fix it and be done.
Yeah me neither but the internet says ....
The brake light cycles every stroke of the pedal. Bet you never had that happen. Tap it hard... it comes off. Then depress the pedal and it comes right back on at two thirds down. You can feel the valve move. The fluid must be going to an accumulator in the ABS cause it ain't coming out but it goes in. So please explain that. This has nothing to do with the hidden air pockets in the secondary valve block. It does tell me something is hung up. Only high pressure hits might knock it loose. I doubt resetting the truck at the battery will do anything to home the valves.


Done done and done dood... wish it was always that easy. Worked on bigger problems so it will get fixed or changed. I been building brake systems for over forty years. This truck has never ever did this. Taking it to a guy who spends all day to tell me it needs a valve body and spending 300-600 for that plus parts is not my idea of money well spent. It might shake something loose on the purge cycle might not. Point is it should not be doing this. I been doing this since like five or six years old with my dad and others. Long line of hot rods go way back. Pump, hold the brake, light, bla bla bla. My dads first body shop partner in 1979 just retried from doing brakes at Sear Service Center. He was the master of light trucks and cars. Smart guy taught me a lot with one other hydros guy. We all were street rod builders and racers of many things. Simple stuff man. Combine those and most things are easy related to fluids under high pressure. I'm also trained in heavy equipment repair, automatic transmissions, CV, wet clutches and fluid drives. Fixed a lot of Ford transmission valve bodies and too many *s-wordty Chrysler brake systems. Lincoln mark eight and Chrysler NYers :thumbsdown: along with countless other piles of chit.

Not much, just aligned tires on a friends Ram and gonna go change a friends oil on a Civic EX. You get the brakes figured out? Ed basically said what I was gonna type up lol. Fly me up there and I'll come straighten it out and delete the ABS *B-S....

Tripping the ABS pump just bleeds air back to the main system for removal. Pick your method. It won't change anything but might reset a stuck valve. That just fixes a spongy pedal. Had this discussion this morning with Mike. If the valves don't reset to home when the pump shuts of um, Houston we have a problem. Real simple system of accumulators and valves on 310 and 410 valve bodies.

Might.

I'll try swapping the whole wet unit first. Nothing to lose there. Rain is pounding down. Relief is coming. Parts run

You on the road yet? What interstate do you take?
No. The trip got postponed for a month. My father had some unexpected and important meetings for work. So we will be staying here until early July. On the bright side, I get to mod my 490

Gotcha. You probably take I35 but it is always weird to me when I am down there and see signs for I29. I29 is the road we enter the US at if driving. As a matter of fact 20 hours straight up I29 gets you about 10 minutes from my place.
