Success.. so far.
Turned on the key, heard the pump run for 20 seconds or so, then it shut off.
Anti lock and Brake lights extinguished. Yes..
Need to finish bleeding front and rear brake lines. Was getting late, needed a pedal pusher.
Manual calls for old style bleeding for front (push pedal, open/close bleeder) or by pressurizing the reservoir.
I only have the vacuum type bleeder so I'll wait til I get an assistant.
Hopefully my accumulator and relays are all good. Will know pretty soon.
Job was not an easy one.
Took a bit longer to install the unit than to remove it. And removing took a while! Back is a lil sore today.
Mistakes made -
Should have taken pics of the brake line arrangement.
When I removed the three brake lines, each used a different wrench size (7/16, 9/16, and 12mm).
I assumed they all had a unique diameter/pitch nipple.
Two of the three lines do have the same diameter and thread pitch.
Installed those in the wrong ports the first time.
Fortunately I caught this before moving on. It just didn't seem right.
Skipping the bench bleed.
Assumed with the accumulator off (I left it off to make the install easier), the pump chamber would fill when I put fluid in the reservoir. It didn't
Took a while but fluid finally got to the chamber.
Not sure what worked. Either gravity, running motor forwards & backward, or putting positive & negative pressure on the reservoir opening.
Using a motorcycle battery hot wired directly to the pump connector, I controlled running the pump by tapping or holding the jumper to the battery post.
Tap battery, get bubbles in the accumulator port, rinse repeat...
That was taking too long.
I finally got smart. Used one of fittings from a Master Cylinder bleed kit (Advance Auto) and ran a line from the accumulator port to the reservoir.
Ran the motor for 10 seconds or so quite a few times to clear all the minuscule bubbles.
Everything after that has gone as expected.
Writing this down to help anyone that might DIY this project later.
Interesting little piece I found in while cleaning the firewall area.
Assuming it's off the assembly line.
