is recalibration required for a brake demand sensor on a bendix abs system

This is a dual diaphragm booster and ABS unit from a '99, (should be same as '96) The PO had replaced the entire system from the dealer 2 years prior to me purchasing it, and it still failed. I know this from experience, as I had to remove and replace my ABS unit in my '91. No power to pump, and no signal to the modulator will leave you with no fluid pressure, and manual brakes that barely work. Pulling the fuse/relay for this will disable the system because the system uses the electric pump to create pressure to apply the brakes. It is necessary to remove the entire system on a '91 and older because the system does not use a vacuum assisted booster, but an electronic pump, an accumulator, and a modulator. (pump and accumulator not pictured, but are located on passenger side of engine bay) This is the Bendix ABS system on 91 and older vehicles. So what is the difference between the 'early' and 'late' years that you say you can just remove fuses and relays? However he says it is still better to remove it all on the 92 and up also. And that is what was worrying me about it as far as my XJ. I just texted him and he said it was a 91. He said she had an issue where it wouldn't let her put on the brakes, so they removed all the ABS stuff from the vehicle. On my friend's sister's 91 they had to remove everything. However when wheeling offroad there are situations where the non-ABS is preferable. Granted for the majority of normal town and highway driving the ABS system is preferable. Reality is that both systems have benefits and drawbacks depending on the specific braking instance in question.

Bottom thought here is that is most likely the reason that the original Bendix system was replaced with the upgraded one perchance?Īs for taking a system back to the non-ABS configuration, that was still an option from the manufacturer so that wouldn't be playing 'russian roulette' other than back into the old argument as to whether the non-ABS or the ABS system is preferable or safer. Under the original design of the system, it had to enter into the design and safety issues and considerations that the ABS system would not work for one reason or another, like a pump failure or lack of power to the pump, so in that case the brakes would still have to function correctly or else the vehicle manufacturer would be liable for accidents, etc. I refuse to recommend to anyone else that they do something quite so unsafe. Play Russian Roulette with yourself, your vehicle, your passengers, and anyone on the road in front of you all you want.
