At this point, I'm thinking I just want to get rid of the ABS. I do value the originality of the car, but I also value actually driving the car, not constantly fixing the ABS. That's not something I'd want to fix myself, and I don't want it to become a money pit, dragging down the car, and my wallet. The accumulator is bad as stated earlier, and while I did find a junkyard one, I'm not sure how long it'll last. If it's around $450 to fix the whole assembly, I think it would be worth it just to spend the extra $150 for the Bosch hydro boost system. I'm a bit uneasy on sort of frankensteining a vacuum system together from different vehicles. With the hydro boost system, it would be backed up by Bosch if it broke. The same company does make a vacuum conversion kit for cheaper, that could be an option.The Teves system does give really good, solid pedal feel, which I like. And it's technically interesting (not that it matters too much on a daily driver!). I have had failures of the ABS relay and the pump motor. So I can't say it's trouble free. But I have kept it (doing the work myself) because it was the simplest way to get the car working again, kept it original (again, this may not matter), and wasn't all that expensive.
To me, fixing it was the best option. But in your case, it may not be. I don't know the status of your accumulator, pressure switch, and pump motor brushes. If it was my car, I would replace and rebuild all that at the same time, because it's not actually a fun job to pull this MC and pump out. That adds up (about $100 for the switch, $150 for the accumulator, and say $200 for a motor rebuild). So there's $450 for everything. Also, the motor rebuild does take a little time to ship out and get it back.
(Hmm, I just found a NOS pump & motor & pressure switch on eBay for $495. This is a good find! They don't come up that often. http://www.ebay.com/itm/NEW-OEM-For...ash=item25b51e790f:g:r2cAAOSwCypWnntM&vxp=mtr)
In your case, if the pump motor, accumulator ball and pressure switch are working, you could leave those and just do the pump motor seal for about $5 plus labor. (By the way, I just received my order of these yesterday ... I still need to look them over and check the material, and then they will be available for SCCoA members.) But think of the mechanic's labor costs if you have to pull the system out again in 6 months to fix the next part.
The hydroboost system looks like it's about $600? If so, I would say that system is a decent option. But you would lose ABS, I think?
The vacuum conversion is a decent way to go as well ... but again, you lose ABS.
So think about it and let us know what you decide.
Im trying not to obsess over cost. My parents have assured me that they will take care of the repairs, since I need good brakes to drive safely, and I can't work right now. I just want to make it as painless, and as cheap as possible for me, and for them. But again, I need to remember that sometimes it's best to spend more, and be done with it.
Thanks for the help! I'll talk it over with the mechanic, and see if he can do it.
