I was told by the mechanic that the ABS, booster and master cyclinder are all one unit and it's a very expensive fix. I'm new to this Mark VII thing so I'm unsure of what my options are. I thought I had read something about converting over to mustang parts and doing away with the ABS. Mustangs are a dime a dozen in our salvage yards so I thought that might be one way to go. Just looking for advice, thanks.
The "scary expensive ABS unit" story is an old one for Mark VII owners. 95% of the world has no clue how to work on one, so they jump directly to telling the owner that its the $1200 ABS assembly when in reality it may be a cheap relay. The air suspension system is the other "big scary" system, and for the same reason. Armed with the factory shop manual and a voltmeter, you can troubleshoot a whole lot on these cars, and more often than not fix it for a reasonably small sum and with a whole lot less labor than changing it to something else.

It isn't hard to troubleshoot, but after owning 2 cars with this system, I can tell you it's crap.
Too many parts to go bad, and most are expensive.
The real problem is that electricity is used for something that should be mechanical, hence making it far more prone to failure.
More parts, more complexity, more problems, just how it goes.... take it from me, I owned an 89 Jaguar, lol
The relay is cheap, but nothing else is.
If u do indeed switch you need:
93 Cobra Booster
93 Cobra Master (recomended)
or if u can find one, a 95 Cobra R master cylinder...
And whoever said SN95 brakes a smaller.....
I'm pretty sure they are bigger and better.
Hence why us mark guys swap SN95 parts into our front ends.

Tho the best way to upgrade the brakes is to swap in 96+ Mustang spindles, thus allowing usage of the decent ford factory options.
I plan on investing in dual pot calipers in the front on mine with slotted rotors and Hawk Pads. Rear I'm prolly gonna just do new calipers, hawk pads and slotted rotors.
And if you plan on auto crossing a Mark, please please please invest in a decent brake cooling setup aswell as a p/s fluid cooler.
Lots of weight and even if your already lighter, a cooler setup will run better and be more reliable!
