OK, I post this every 6 months or so, just in case someone new comes on board that can help.
On the 89-91 XJ, with the first ABS, Bendix 9 & 10 systems.
They are junk and have a high fail rate due to design flaws.
The NHTSB requires the dealer to warranty the main parts for life, but the best thing to do is to take out the ABS master cylinder and pressure motor and just replace it with a stock hydraulic brake system.
I have seen one tech article, but failed to print it off.
I know you can just remove the ABS master cylinder and pump and take a stock hydraulic master cylinder and vacuum booster from a 92 or so XJ and bolt it on and have a better, safer system, esp for wheeling. There was just a small issue of replacing the actuating rod with one slightly longer that I don't know about.
Has anyone out there done this or know of someone who has???
