your last post did offer some greater insight.
first off, I do not have experience with the brake boosters on our cars. I thought it was a vacuum with no fluid. SoCal learned my something new and that bad news is if our boosters have power steering fluid running through that contamination is why your friends friend is telling you the whole system needs replaced. Brake and power steering fluid are nothing alike. The first time the brake pedal was pushed power steering fluid was all through the entire system, and it will destroy every seal in your break system it touches. I do not know of anyway to flush the entire system. and more than likely the damage has already been done.
I'm sorry dude, that really sucks. not surprising the guy does not want to talk with you. I don't know much about lawsuits and what not, so I dunno how that turns out.
Regardless I agree with SoCal, that it should not cost 3 grand to fix (even replacing everything). I think you could gets all the parts for half of that or less.
Quote at the shop today for first shop formal estimate was $4,050. The ABS module alone is like $1300 apparently... I was in the room when they called the local Ford dealer as no part can be found at NAPA or the like. The local Ford dealer said customer retail is $2,200. That is insane.... I can't disclose the actual cost the shop I was at pays as that is confidential, but the price they are able to offer me on the part is right around $1300.
Plan to go to Ford tomorrow, but assuming they will be more if they don't discount their ABS module... ha
Problem with getting quotes from places is their techs may be like my friend who doesn't really know the issue and they start guessing it could be this or that. So I have to wonder how this process will go...
As far as the legal matter I will have to post back on that as I know from pre-law classes it is not advisable to discuss on going legal matters should this situation escalate and move to that... The main reason for this post is to hopefully obtain information on my situation and assess how to move forward as ultimately I want to get the car on the road and have the car live the good life it was built to do...
Trying to learn more about the hydroboost system, so i can offer more help. From looking at my mustang and reading a little online. I am not sure that that brake fluid (even thpugh powering the booster) actually could get into the brake system via a bad seal. Again I am not familiar with the hydroboost, so i am not certain of this. If the fluids are in seperate casts, the only way ATF could be introduced into the brake system is if the previous owner directly poured it into the brake resv. If that is that case than it sounds like your s.o.l. again like SoCal said, it should be easy to tell (based on color) if it is actually ATF. Best case is that they have not mixed and the brakefluid is just in need of replacement.
I am not sure how the hydroboost system works either. If you find a good diagram let me know. One that shows you that fluids shouldn't mix would be helpful as it sounds like that may be what you found...
Fluid looked dark and not like normal brake fluid. Orignally thought to be water and dirty causing this considering the fluid was 15 years old.
