Happy Monday!
Thought I would share our progress on the ABS Modulator Pump. Had some good wins and overcame some hurdles. Attached are some pictures for reference.
Took about an hour to get the pump out of the car, not too bad. The driver side brake lines are a little tough as the access is more limited. The next obstacle was to get the cap off the main 12mm allan head bolt that holds the 2 ABS pump housings together. We found that we had to make a score or groove in the cap, and then this allowed us to finally pry it off. Thought we were all good from there, but turns out this main bolt is a monster to break loose! Maybe ours was just seized a bit. But we had quite a challenge to apply enough leverage to break it free. Ended up having to mount a vice to the bench, bolt the vice so it wont swivel, and then use a break bar with a floor jack handle as an extension. After about an hour or more, we were able to get it free.
Taking apart the ABS pump and cleaning it, actually went quite well. Pretty straight forward. We pulled out the 3 solenoids one at a time, taking care to remove the small screen, spring and ball bearing. Cleaning it all thoroughly and then reassembling it. There is a screen on both sides of the solenoid that we cleaned. Also took care to make sure the rubber o-rings are seated properly before reassembly. Went back together with no issues, as far as we can tell. We also blew air through the hard line from the ABS pump to the Right Front, just to make sure it wasn't blocked. Seems good.
So where are we now. We are stuck at the reinstalling it into the car stage haha. Of all the silly things, we cannot get the first brake line to thread back into the housing. It's a tough one to reach, so space is tight. Try to screw it by hand, but it gets stuck and as soon as we put a wrench on it, it pops out. Honestly, I understand if you don't believe me haha. Spent maybe close to 2 hours trying to get the first line on. Ended up calling it a night, before we ended up making something worse lol. Maybe we are being too careful not to stripe the threads. So that's where we are at now.
The one idea we have is to lubricate the threads and hopefully that allows us to get the nut started by handed further. If anyone has any tips or ideas we are all ears!
Thanks again to
