Update time. So my friendly local diesel shop replaced the master cylinder first and when that didn't work were like "we need to do the HCU". Now that was **** expensive and ... didn't solve the problem. They bled it a dozen times and gave it back with the whole "the rears are filling up that's your problem."
So since then the pedal has remained soft and I can pump it up and then push and it drops to the floor, pump it up from there, push and it drops to the floor. It's also slightly worse cold. That all just
screams master cylinder right?
Anyway this week I finally made time to take it to a high end 4x4 shop here. By high end I mean the "shop car" they run you back in is a brand new Colorado pickup and a simple rear diff fluid exchange tops $250 (ask me how I know).
In any case I explained at length and the tech was like "master cylinder" about half way through. I'm like well you would think that but this other shop just did that and the HCU.
So of course the first thing he does is by-the-book cap all the brake line ports from the master cylinder and the pedal still creeps to the floor. Of course that's under warranty at the first shop so while I consider paying "dipped in gold" rates to just have it
done, I instead take it back to my friendly local shop.
First thing he says is "well we already replaced that master cylinder
twice." and I'm like "Twice? This is the first I'm hearing about
twice."
Anyway they remained convinced there is no way it's the master cylinder but "they'll look at it again". I'm seriously wondering now if they ever replaced the master cylinder once, much less twice and if two units failed why are they still using that supplier?
Seriously I want to like this shop but when I took my van back for emissions recently the guy at the desk literally paled when he saw me. I have a really hard time believing that he doesn't
know they botched it and was literally just waiting for me to come back on them.
AAAARRGGGGH! I just want the **** thing fixed right. If they can't pull it out this time I feel like I need to go to the new shop and pay AGAIN to have it redone.
