Need help fast- Brake conversion needed from anti-lock bendix 9 or off to junk yard!

Hello Sirs, Sorry to be so formal,
BUT, I have a BIG decision and little time to talk me out of sending my baby to the junk yard:;
I have a 1989 Woody Limited which unfortunately came with the Bendix 9 anti-lock brake system and I am having a fit with it. Many parts are discontinued or/ very expensive! I have heard of brake system conversions, but I am scared of too much work with time restraints and cash flow.

My question is:
Should I just send her down the way to the bone yard, or is there hope that there is a QUICK/SIMPLE fix to get her to stop again and not break my buget or take a bunch of time.
I need a bunch of instructions from someone who has done this conversion and a ball-park figure of the cost.
A parts supply list and any experience quotes would be greatfully appriecieated real soon before I regret sending her into the junk yard.

Please, please help, if you feel i am going to make a mistake getting rid of her!!!

The ABS in my wife's old Explorer was utter crap.... couldnt stop on a dry road. We just pulled the fuse and lived with the ABS light. Not an option on these?

in know on the XJ you can just disable the ABS by pulling the relay or fuse. The system used on the early XJs and probably MJs was almost useless to begin with.

fuse don't cut it. sorry!

Just pulling a fuse wont help me. This Brake system has a pump system that pulling a fuse doesn't help.( I tryed).. I am mainly asking about a conversion and wether it is worth the time or effort. I have my kids drive this vehicle if needed and just pulling a fuse to get rid of a light is not an option. I definetely need better brakage, or this car is toast. I need a Bendix 9 expert to reply here please!

Yeap, pulling the fuse on the bendix brakes certainly does not work.

What you need for the conversion is:
* booster + mc from 95+ xj (also zjs and wjs work, wj boosters needs a spacer though)
* brake proportioning valve from a non-abs xj
* I suggest replacing all brake hard lines; minimum is IIRC front driver and passenger side, and you also need the short tubes between mc and prop.valve.

Don't ask about flare nut sizes, can't remember those

Remember when removing the bendix system, that there will most likely be some pressure in the system so brake fluid may spray out. Keep some rags close by when unbolting any connections.

Timo,
That is the answer that I was looking for. How long did this project take you and what was the "ballpark" cost?

Back then I hadn't been doing much brake work so I took my time, was done in one full day for the brakes including bleeding, a few hours the next day removing all the unnecessary ABS- wire harnessing.. I did buy pre- flared hardlines that I had measured for correct length which made it a little quicker.

Price depends on if you're using junkyard parts or factory-new/ remanufactured. Considering you're working on the brakes, I'd use the latter - I wouldn't trust JY parts on brakes except for the prop. valve. MC + booster can be bought for ~150$, pre-flared hardlines shouldn't set you back more than 50$, brake prop. valve from a JY 15-25$, some other misc. stuff if you break something..

One thing to consider, you may need to modify your brake pedal to work with the newer double- diaphragm boosters. Pre- '95 should be a bolt-on, but I've seen people use the 95+ boosters that bolt-on directly to the pedal. I myself needed to drill a new hole and use a DIY- spacer, that was it. You only know when you get to the point of connecting the pedal to the booster rod.

It wasn't too hard. I did it with junk yard parts in a day. Booster, master cylinder, and porp valve all for 75 bucks. I also just used compression fittings and hooked to my factory hard lines. If you have a tube bender and flare set you can do it for under a hundred bucks. I did not need to modify my pedal either. Just make sure you get all the stuff from the jy. (vacuum fitting in booster and hose that attaches to it and fitting that goes in the intake. And the spacer from between the firewall and booster.) pm me if you need help and I'll give ya my phone #.

I'm considering doing this to my 1990 Wagoneer limited and I found that both Summit and Autozone have a booster and MC that are spec'd for models without ABS the combo from Summit is only $130.00.
Anyone know if '90ish XJ's were available without ABS?
Or are the Websites wrong/miss informed?
